PITTSBURGH – DJ Herz had Tommy John surgery today, officially sidelining the Nationals left-hander for the 2025 season after three weeks spent hoping the major elbow procedure would not be necessary.

Herz had his elbow ligament replaced by orthopedist Keith Meister in Dallas, according to manager Davey Martinez. He did not get the additional internal brace procedure some pitchers, including teammate Josiah Gray, have opted for in recent years.

Today’s news came three weeks after Herz landed on the 60-day injured list with a sprained ligament, an ailment he reported after the Nationals initially optioned him to Triple-A Rochester following a disappointing spring in which his velocity was down. The 24-year-old sought opinions from three doctors, hoping one of them would offer him the option to come back via rest and rehab only, but there was consensus on the need for surgery.

“Have hope. Have faith,” Herz wrote on his Instagram account below a photo of him in a hospital bed following today’s surgery. “The only easy day is yesterday. Believe in something you can’t see. Buckle down and keep believing.”

Acquired from the Cubs in July 2023 for Jeimer Candelario, Herz had been one of the pleasant surprises of the 2024 season, posting a 4.19 ERA and 106 strikeouts over 88 2/3 innings while authoring some of the Nats’ most dominant starts of the year.

CJ Abrams has his first day off of the young season, not because of a bad matchup or a planned respite, but because of a tight thigh muscle.

Nationals manager Davey Martinez said the shortstop felt his right thigh tighten up while making the final play of Sunday’s 5-4 win over the Diamondbacks. Abrams charged in to field Randal Grichuk’s broken-bat grounder in the top of the ninth, then threw on the run to first, nearly pulling Nathaniel Lowe off the bag.

“He feels a little bit better today,” Martinez said. “I just wanted to give him a day, to make sure this doesn’t become a big issue.”

Asked what level of concern he has about Abrams, Martinez replied: “Right now, none. Hopefully it could’ve just been a cramp. But I want to make sure that’s just what it is.”

Abrams not only had started all nine previous games this season, but had played every inning to date. Martinez’s choice of replacement may come as a bit of a surprise: Paul DeJong.

DJ Herz is getting a second opinion on his sprained elbow ligament, one that will determine if the Nationals left-hander needs Tommy John surgery or can attempt to come back merely with rest and rehab.

Herz, who was placed on the 15-day injured list Tuesday and then transferred to the 60-day IL on Wednesday, already had an initial MRI taken that revealed a sprain of the ulnar collateral ligament. He’s now scheduled to get a second opinion in Dallas from Keith Meister, the noted orthopedist who has performed a number of Tommy John surgeries and internal brace procedures on other major leaguers. According to a source familiar with the injury, the Nationals don’t intend to wait long if surgery is suggested, preferring Herz get it done now and be able to return for the majority of the 2026 season.

Herz was one of the brightest developments of last season, debuting in June and proceeding to make 19 big league starts, going 4-9 with a 4.6 ERA but also authoring several of the team’s most dominant starts of the year. He came to camp this spring competing with Mitchell Parker and Shinnosuke Ogasawara for the fifth starter’s job but struggled with command and saw his fastball velocity drop into the upper 80s.

Herz told club officials and reporters alike he was physically fine, but that he wasn’t throwing as hard due to a lack of adrenaline. He cited similar situations playing out in previous spring trainings, noting his velocity always showed up during the regular season.

The Nationals saw some better signs during a simulated game Herz pitched late in camp, but still decided to option the lefty to Triple-A Rochester last week, giving him more time to build his arm up. After learning of the demotion, Herz informed the team he wanted to see a doctor in case there actually was something wrong with his arm.

Well, just yesterday morning I took a look at the Nationals’ overall roster depth ahead of the regular season starting. I noted the importance of organizational depth as the baseball gods are unpredictable and unforgiving when it comes to injuries.

Sure enough, the Nationals announced just over an hour after my post published that left-hander DJ Herz was placed on the 15-day injured list with an elbow UCL sprain. And although we won’t have more official information on the situation until tomorrow, that injury is usually associated with Tommy John surgery and/or an internal brace procedure, which would sideline Herz until 2026.

Luckily, the Nats are confident in their organizational depth, which they believe is deeper than it has been in recent years and can help sustain a successful season.

Herz was to be a part of that depth, having been optioned down to Triple-A Rochester on Friday after a rough spring that included a bout with dead arm. The southpaw was coming off a rookie season in which he went 4-9 with 4.16 ERA while pitching some of the Nats’ most dominant starts of the season, including six innings of one-hit ball with 13 strikeouts on June 15 against the Marlins and 10 strikeouts with one run allowed July 2 against the Mets.

But after finishing four Grapefruit League starts with a 6.52 ERA, 1.966 WHIP, nine walks and only four strikeouts in 9 ⅔ innings, the Nationals decided to get Herz more seasoning in the minor leagues. And now an elbow injury has derailed his season.

The Nationals placed DJ Herz on the 15-day injured list this morning with a UCL sprain in his elbow, a potential season-ending ailment for the left-hander that would explain his spring training struggles.

Herz had been optioned to Triple-A Rochester on Friday, capping off a difficult spring that saw the 24-year-old deal with diminished velocity and poor results while ceding the No. 5 starter competition to fellow lefty Mitchell Parker.

At the time, club officials suggested Herz simply needed more time to get his arm in shape and that he would be in the running for a promotion back to the majors once he looked more like himself.

“We know his velo was a little bit down, but just go down there and start getting built up,” manager Davey Martinez said Friday after the demotion was announced. “And understand that last year, he only had (19) starts. He hasn’t pitched that much. So he’s going to go down there and get ready to help us.”

Herz was one of the brightest developments of the 2024 season for the Nationals, called up to make his major league debut in early June and then remaining in the rotation for most of the remainder of the year. He finished with a 4-9 record and 4.16 ERA, but he authored some of the team’s most dominant starts of the season, including six innings of one-hit ball with 13 strikeouts against the Marlins on June 15 and 10 strikeouts with one run allowed July 2 against the Mets.

WEST PALM BEACH, Fla. – The Nationals have chosen Mitchell Parker as the final member of their Opening Day rotation, a decision that became official when they optioned both Shinnosuke Ogasawara and DJ Herz to Triple-A Rochester.

The Nats also optioned infielder Nasim Nuñez and catcher Drew Millas to Rochester, narrowing their list of remaining candidates for the last spot on the bench and the backup catcher to two apiece.

The competition for the fifth starter’s job was the most compelling one in camp from the day pitchers and catchers reported last month. Any one of the three left-handers could have claimed it, but ultimately it was clear Parker deserved it over the others.

Parker, who went 7-10 with a 4.29 ERA and 1.305 WHIP in 29 big league starts last season, had a solid-but-not-spectacular spring. Over 12 1/3 innings, he posted a 3.65 ERA and 1.216 WHIP, improving each step of the way.

Manager Davey Martinez hasn’t announced his rotation order to begin the year aside from naming MacKenzie Gore the Opening Day starter, but Parker has been lined up for a while to pitch the third game, the Nationals perhaps preferring to use a lefty against the Phillies lineup.

WEST PALM BEACH, Fla. – The Nationals won’t be carrying a Rule 5 draftee on their roster this season.

The club returned Evan Reifert to the Rays earlier today, conceding the struggling reliever wasn’t going to be able to not only crack the Opening Day roster but remain there the entire year. He now heads back to Tampa Bay, which left him unprotected over the winter but now gets him back as a minor leaguer.

The Nats hoped Reifert’s swing-and-miss stuff – he struck out 14.9 batters per nine innings in four seasons in the Rays system – would translate to the big league level and make him a worthy choice for the Opening Day bullpen. But the right-hander struggled mightily with command from the start of spring training, walking 12 batters in only 6 1/3 innings, and never found it.

“His stuff is really good,” manager Davey Martinez said. “He just wasn’t able to find the zone consistently. We were hoping other things might have happened. Tampa took him back.”

The Nationals initially paid $100,000 to selected Reifert away from the Rays in December’s Rule 5 Draft. They’ll now get $50,000 back after letting him go. Had Tampa Bay turned him down, the 28 other clubs would have had a chance to claim him off waivers but inherit his Rule 5 status and thus keep him on their major league roster the entire season.

PORT CHARLOTTE, Fla. – The fifth starter competition in Nationals camp has been less a spirited battle and more a war of attrition. One that may leave Mitchell Parker as the last man standing when the team heads north in 10 days.

DJ Herz seemingly had an opportunity to make a case for himself this afternoon against the Rays, but it turns out the Nats planned all along to limit the young left-hander to no more than 60 pitches in response to his diminished velocity this spring.

So, Herz was pulled after three innings and 56 pitches (only 30 of them strikes). He allowed just one run, via a towering homer by Brandon Lowe, but he also surrendered a double and issued two walks while striking out just one batter during an eventual 14-4 drubbing by Tampa Bay. All this while throwing a fastball that topped out at 91 mph. (He averaged 93.5 mph last season.)

“We just battled, just found a way to get outs,” he said. “It might not have been the most efficient, but we found a way to get outs. I think we had planned already it was going to be 60 (pitches); we just cut it.”

One of the brightest spots of the 2024 season after making 19 starts, several of them among the best outings anyone on the team had, Herz has looked less than impressive this spring. Over 9 2/3 total innings, he has allowed nine runs (seven earned) on 10 hits, walking nine while striking out only four.

PORT CHARLOTTE, Fla. – Hello from the Gulf Coast of Florida, the opposite side of the state from where you usually hear from us. The Nationals are making a rare overnight spring training trip, with back-to-back games against the Rays here in Port Charlotte and then the Braves in nearby North Port. Most of the regulars have made the trip and will play in both games before heading back to West Palm Beach on Friday night.

DJ Herz takes the mound for what is arguably an important start for the young lefty. With the race for the fifth starter’s job still wide open, Davey Martinez and Mike Rizzo are just waiting for somebody to step in and seize it. Mitchell Parker made his case with a strong start Monday against the Marlins. Herz now gets his chance to make his own case this afternoon against Tampa Bay.

The Nats lineup includes the starting outfield trio of Alex Call, Jacob Young and Dylan Crews, with James Wood serving as the designated hitter. Luis García Jr. is starting at second base. And CJ Abrams is leading off and starting at shortstop after coming out of Wednesday’s game in the first inning with cramps in both quad muscles.

WEST PALM BEACH, Fla. – With 11 days to go in spring training, seven starting pitchers competing for five jobs and a rare, cross-state, overnight trip looming, mapping out the Nationals’ rotation schedule is no simple task for manager Davey Martinez and pitching coach Jim Hickey. They finally settled on a plan this morning, one that takes all of those factors into consideration.

MacKenzie Gore is starting this afternoon’s game against the Astros. It’s only his second official start of the spring, but the left-hander has still been throwing every five days, whether on a back field against minor leaguers or in a simulated game against teammates.

While Gore faces Houston inside CACTI Park of the Palm Beaches, Trevor Williams is facing minor leaguers outside the stadium. The veteran right-hander, who Martinez confirmed this week will open the season in the rotation, has already made three Grapefruit League appearances.

DJ Herz will take the long bus ride from West Palm Beach to Port Charlotte on Thursday morning and then start that afternoon’s game against the Rays. Herz, who is competing for the fifth starter’s job, has looked shaky so far in three Grapefruit League outings, walking seven while striking out only three in 6 2/3 innings.

Jake Irvin’s turn comes up Friday, but the right-hander will stay back in West Palm Beach and face minor leaguers instead of traveling to North Port to face the Braves. That makes Friday’s game a bullpen game for the Nats, with a host of relievers set to pitch one or two innings a piece.

WEST PALM BEACH, Fla. – Progress in early March looks different than it would later in the year, or even in the spring. The Nationals still have two weeks to name a fifth starter, which means DJ Herz still has three more exhibition outings to make his case.

So even though this afternoon’s start during a 5-3 loss to the Cardinals didn’t look great on paper, both Herz and manager Davey Martinez were able to point to some positive developments that represented progress from his two previous appearances.

“He threw a lot of strikes,” Martinez said of Herz, who was credited with 46 of them among his 71 total pitches. “The big thing with him is, he got ahead, and then he got hitters back in the count: 3-2, 2-2. Once he gets ahead, he’s got to stay ahead. But he did throw the ball around the plate. It was way better today. A better outing for him today, so we’ll build from that.”

High pitch counts and an inability to throw strikes were the defining characteristics of Herz’s prior spring starts, most notably last week’s effort against the Astros in which he walked four and didn’t even make it out of the second inning.

The lefty again got himself in trouble in the top of the second today, with two runs scoring on three hits, and a leaping catch in center field by Jacob Young saving the inning from going on any longer. Even so, Herz walked off the mound with his pitch count already up to 48, a product of all those long at-bats, most of which lasted at least five or six pitches.

WEST PALM BEACH, Fla. – The Nationals have a quick turnaround from Friday night’s walk-off win over the Mets, facing the Cardinals today at the extra-early time of 12:05 p.m. Davey Martinez decided to let the guys sleep in a little, canceling formal morning workouts and batting practice. And most of the regulars who started Friday night are not in today’s lineup.

DJ Herz should be well-rested, though, and eager to perform better than he did in either of his previous two spring starts. The young lefty has been pulled with two outs in the second each time, having allowed two runs. He’s also walked six in those 3 1/3 combined innings while striking out only two, the exact opposite of what should be expected of him. He’s in a battle with Mitchell Parker and Shinnosuke Ogasawara for the No. 5 starter’s job; this would be a good time for him to step up and make the case for himself.

The Nationals lineup faces veteran left-hander Steven Matz. With many of the regulars sitting, Jacob Young gets a chance to lead off, with Robert Hassell III bumped all the way up to the No. 2 spot.

You can watch today’s game live on MASN, with Bob Carpenter and Kevin Frandsen together on the call for the first time in 2025. The radio broadcast with Charlie Slowes and Dave Jageler, meanwhile, is streaming online only today.

WEST PALM BEACH, Fla. – The Nationals know they need to hit for more power in 2025. They hit the second-fewest home runs in the major leagues last year with 135, only two more than the woeful White Sox.

The offseason additions to the lineup are supposed to address that lack of power. They already know Josh Bell’s homer potential. They believe Nathaniel Lowe can tap into the power he displayed in Texas. And Paul DeJong, while not known for his batting average, has been able to provide some pop throughout his eight-year big league career.

Bell hit his first home run in yesterday’s loss to the Cardinals, a two-run shot for the Nats’ only runs in the first game of their split-squad doubleheader. Lowe has yet to go long. And DeJong finally went deep in today’s 4-3 win over the Astros.

Against Astros closer Josh Hader, DeJong got ahead in the count, ran it full and drove the seventh pitch over the visiting bullpen in left field. There are no Statcast measurements at CACTI Park of the Palm Beaches, but it traveled far.

“He's been good. He's been really good,” manager Davey Martinez said. “Another veteran guy that knows himself really well. When he connects, he can hit the ball a long way. We saw that today. What I really love, though, is that, honestly, he plays defense really well, too, which is going to help us. It really is. We know when he's up there, he's got a chance to put us in the lead. And I love that about him. So he's been great.”

WEST PALM BEACH, Fla. – After some initial confusion this morning, James Wood will return to the Nationals lineup as the designated hitter for this afternoon’s spring training game against the Astros.

Manager Davey Martinez said after Wood’s spring debut Friday that the towering outfielder would DH again today. But when the Nats lineup was initially submitted, it did not include Wood and instead had Josh Bell batting fourth as the designated hitter.

A brief moment of panic and concern was quickly quashed by Martinez in his pregame media session. The error was caused by the skipper’s habit of filling out lineups days in advance and not knowing Wood’s availability while doing so earlier this week.

There were no setbacks or anything of the sort. All is well.

“He's feeling good,” Martinez said of Wood, who has been dealing with right quad tendinitis. “Depending on how long the game goes, we'll hope to get him three at-bats again. Then we'll see how he's doing.”

WEST PALM BEACH, Fla. – It was a two-out walk in the first inning on Feb. 26. Not that big a deal, right?

For DJ Herz, it was a big deal. Not because the result of today’s exhibition game – a 3-0 loss to the Astros – was important. But because he knows two-out walks are among his biggest bugaboos, something the young left-hander is really trying to focus on correcting this year.

“Obviously, we don’t want to do the two-out walks,” Herz said. “A lot of weird stuff happens when that happens.”

What happened after this two-out walk of Isaac Paredes? A two-run homer by Yainer Diaz. Then back-to-back singles. And suddenly, what could’ve been a quick, 1-2-3 top of the first turned into a laborious 24-pitch frame.

So, even though the game didn’t count, is the two-out walk in spring training that important?

WEST PALM BEACH, Fla. – The undefeated Nationals have looked good so far in the early stages of the exhibition season, especially a lineup that has scored 31 runs in three games. That group has done well in the first inning, scoring five runs against the Mets and three runs against the Marlins.

The challenge is quite a bit tougher this afternoon when the Nats face Astros ace Framber Valdez. The veteran left-hander will be on the mound for his first outing of the spring, facing a lineup featuring a few regulars.

Those regulars include CJ Abrams, Luis García Jr., Keibert Ruiz and Nathaniel Lowe at the top of the order. The bottom of the order includes a familiar name in an unfamiliar position: Juan Yepez in left field. Given the offseason additions of Lowe and Josh Bell, Yepez’s only real shot of making the team is to prove he can adequately play something other than first base. So he’ll get a shot this afternoon in the outfield. He’s also been taking some reps at third base during workouts.

DJ Herz makes his spring debut on the mound. The young lefty seemingly is competing with fellow young lefties Mitchell Parker and Shinnosuke Ogasawara for the No. 5 starter’s job, but it’s still too early in camp to see exactly how that will all play out. For now, the Nationals just want Herz to throw strikes and pitch with some consistency as he tries to prove he’s the right man for the job.

WEST PALM BEACH, Fla. – By any reasonable measure, DJ Herz’s 2024 season was a success. The young left-hander pitched well enough in 10 starts at Triple-A Rochester to earn a promotion. And then he pitched well enough in 19 starts with the Nationals (4.16 ERA, 1.263 WHIP, 106 strikeouts in 88 2/3 innings) to feel like he had established his big league credentials.

That should guarantee Herz a spot in the Nats’ Opening Day rotation this season, right? Not at all.

When the team signed two major league veteran free agents (Michael Soroka, Trevor Williams) as well as an established Japanese pitcher (Shinnosuke Ogasawara), the 2025 rotation suddenly looked overcrowded. At least two, maybe all three, of those guys are going to make the rotation. And MacKenzie Gore and Jake Irvin are locks, given their performances the last two seasons and high ceilings for success.

That could leave both Herz and fellow young lefty Mitchell Parker on the outside looking in. Not that they’re bothered by it.

“I feel like we only got stronger,” Herz said of the Nationals’ offseason additions. “For me, I love the competition. I don’t like feeling comfortable or complacent. I like the feeling of: I’ve got to compete and go win a spot. I think it makes me a better player. I’m excited to be with them.”

During the early parts of this offseason, the Nationals were in search of starting pitchers. It didn’t need to be filled right then and there, but the front office brass left December’s Winter Meetings in Dallas without any additions to the major league roster except for Rule 5 Draft pick Evan Reifert.

Patrick Corbin and Trevor Williams became free agents at the end of last season. Mitchell Parker and DJ Herz, while impressive in their respective rookie seasons, weren’t sure things to stay in the big league rotation in 2025.

Josiah Gray is expected to miss most of this year while recovering from his Tommy John surgery and internal brace procedure. Cade Cavalli still needs to prove he can pitch every five days in the majors while working his way back from his own Tommy John surgery.

MacKenzie Gore and Jake Irvin were the only sure things in the Nats rotation heading into the new season.

But then a week after returning home from Dallas, the Nats signed right-hander Michael Soroka to a modest one-year, $9 million contract. On New Year’s Eve, they brought back Williams on a new two-year, $14 million deal. And in January, they signed left-hander Shinnosuke Ogasawara to a two-year, $3.5 million contract, the first ever given by the club to a player directly from Asia.

There are 57 players set to report to Nationals spring training in the next week-plus, 28 of them position players, 29 of them pitchers. That number is a little smaller than in some previous years, but it probably underscores the likelihood of several more free agent signings during these final days of the offseason, or even during the first few weeks of camp.

For now, though, this is your team. Only 26 of them will head north at the end of March and make the Opening Day roster. Obviously, some of them are in far better position to make the club than others, but everyone will get a chance to play in front of the big league coaching staff and front office in West Palm Beach, Fla., and make a case for himself.

You know most of these guys, but you probably don’t know all of them. So with that in mind, let’s run through the entire camp roster, with some quick thoughts on each entering the spring. We did position players yesterday, so today’s let’s run through the pitchers …

DAISON ACOSTA, RHP
The 26-year-old reliever joined the Nats organization last season and put up some impressive numbers at Double-A Harrisburg (2.89 ERA, 1.189 WHIP, 73 strikeouts in 53 innings). He got a non-roster invitation to camp this spring, where he’ll have a chance to prove if his stuff works against big league hitters.

JOAN ADON, RHP
Despite being designated for assignment this winter, the righty is still here, having cleared waivers and been outrighted off the 40-man roster. It would take a lot for him to earn his way back to the majors at this point, though.

Friday’s signing of Shinnosuke Ogasawara truly came out of left field. Not only because the Nationals had never signed a free agent out of Japan (or any other Asian country). But because they didn’t seem to be in the market for another starting pitcher, at least not one who wouldn’t instantly slot into the front of the rotation, as opposed to the back.

Ogasawara, by all indications, does not project to be a frontline starter in the major leagues. He figures to get a shot to earn the fourth or fifth starter job coming out of spring training. But there’s also reasonable speculation his chances of long-term success here will increase if he becomes a reliever.

The Nats didn’t give the 27-year-old left-hander a guaranteed, two-year deal worth a reported $3.5 million, though, if they didn’t expect him to be part of the Opening Day pitching staff. And Ogasawara, whose 45-day negotiating window was set to expire Friday if he didn’t sign with any major league club, likely chose Washington because of the opportunity he’ll get here that perhaps he wasn’t guaranteed to get elsewhere.

We’re scheduled to hear from general manager Mike Rizzo this afternoon, so hopefully we’ll get a better idea then what exactly the club’s plans for Ogasawara are. But if he truly is given a chance to make the rotation, he’s going to join a crowded group of arms competing for only a couple of open spots.

Barring a trade – which, of course, you can never rule out – the Nationals will go into spring training with MacKenzie Gore and Jake Irvin assured of starting jobs, based on their performances last season. That now leaves five others, in theory, competing for three more spots in the rotation.
