As he makes his way back from the injured list, MacKenzie Gore’s biggest challenge doesn’t appear to be the health of his left arm but the sharpness of his pitches.

Gore made his second rehab start for Triple-A Rochester on Friday night, and though he emerged healthy, he did have some trouble keeping the ball over the plate: Only 32 of the lefty’s 57 pitches were strikes.

“When you’re out for a while, part of the rehab is getting yourself back in rhythm,” Nationals manager Davey Martinez said. “The first inning was very clean, they said. The second inning was clean; he walked a batter. And then the third inning is when it really became an issue.”

Indeed, Gore threw 25-of-40 pitches for strikes during his first two innings of work, then threw only 7-of-17 for strikes in the third before getting pulled.

“That could be just a little bit fatigued, not staying on his legs,” Martinez said. “That could easily be corrected by going out there and continuing to build up. But we’ll get him back here. He talked with (pitching coach Jim) Hickey about some of the things he wants to continue to work on in the bullpen, so he’ll come back and work on those things, and we’ll get him back out there.”

The Nationals did the unthinkable and actually beat the Marlins on Friday night. Now they’ll see if they can somehow do it two days in a row and really reverse their season-long struggles against their sub-.500 division foes.

As was the case Friday, the Nats are facing a Miami left-hander. They’ll need to be better against Trevor Rogers than they were against Jesús Luzardo, who didn’t give up a run until Joey Meneses’ inside-the-park homer in the bottom of the seventh. Rogers has not had a good season (4-11, 5.35 ERA) but he’s been quite good against the Nationals (3-0, 2.25 ERA).

On the bright side, Erick Fedde has always been good against the Marlins (4-1, 1.86 ERA in nine career starts) and he held them to two runs on three hits over six innings in his last outing against them on July 3.

As Cade Cavalli deals with another shutdown and Josiah Gray deals with September struggles, the Nationals at least are seeing some positive signs with the third member of the young pitching trio they hope to build their rotation around.

MacKenzie Gore made his second rehab start for Triple-A Rochester on Friday and tossed 2 2/3 scoreless innings on 57 pitches, another step on his path toward making his Nats debut before season’s end.

Gore, on the 15-day injured list with elbow inflammation since late July (before he was part of the Nationals’ blockbuster trade with the Padres for Juan Soto and Josh Bell), built up both his innings and pitch count in his second rehab start for Rochester.

The left-hander did put six Lehigh Valley batters on base in his 2 2/3 innings (four singles, two walks) but didn’t allow any of them to score while striking out two. He threw 32 of his 57 pitches for strikes.

Assuming Gore came out of this outing healthy, the Nats are likely to have him make another rehab start in five or six days, building up to roughly 70 pitches. Depending on how that goes, the club could decide to activate him off the IL with enough time to make two big league starts before the season ends Oct. 5.

First came Joey Meneses’ inside-the-park homer, a huffing-and-puffing adventure around the bases to add the latest improbable chapter to the 30-year-old rookie’s out-of-nowhere arrival.

Then came CJ Abrams’ two-out, two-run triple, an explosive sprint from the plate to third base by the dynamic 21-year-old shortstop.

And when Ildemaro Vargas drove the go-ahead double to left-center in the bottom of the eighth, the Nationals had finally pulled off something they’d done only once in 13 previous tries this season: They beat the Marlins.

Storming back to score five runs in their final two offensive innings, the Nats emerged with a 5-4 victory over Miami, only their second win over their division counterparts this season, certainly the most uplifting to date.

"I look back, and I think about when we play good defense, good things happen," said manager Davey Martinez, whose team indeed sparkled in the field again tonight. "We're playing good defense, we're staying in some of these games. And the hits are going to come, the runs are going to come. Continue to get the defense, get good pitching, and we'll win some games."

Cade Cavalli has been shut down again after experiencing a recurrence of shoulder discomfort in his first throwing session since landing on the injured list three weeks ago, though both the Nationals and the rookie right-hander say they’re confident he’s not dealing with anything more serious than inflammation.

Cavalli had just completed a two-week shutdown period following his shaky Aug. 26 major league debut and was cleared to resume throwing Wednesday. But his session, in which he was going to be restricted to 60 feet on flat ground, had to be cut short when he reported more shoulder soreness.

The Nationals gave Cavalli a cortisone shot and instructed him to shut down for another three to seven days before he attempts to throw again.

“It was a little painful, but we got it all worked out,” the 24-year-old said. “And here in a couple days, I should be back out there throwing again after letting it calm down. I’m very encouraged. I think it’s going to be very good.”

Though the team insists Cavalli continues to deal with only shoulder inflammation and nothing more serious, the fact he was unable to make it through his first throwing session in two weeks has to concern club officials.

The Nationals have been dreadful within the NL East this season, going an inconceivable 11-46 against division opponents to date. But would you have guessed their biggest struggles have come not against the division’s three playoff contenders but the only other sub-.500 team? Somehow, the Nats have gone 1-12 against the Marlins, a shocking head-to-head record when you think about it.

Which brings us to the season’s remaining schedule: 19 games, all against NL East foes, including six against Miami. That’s still a significant 25 percent of their overall intradivision games to go, which could either makes a miserable season even worse or perhaps offer a tiny sliver of good vibes heading into the winter.

Josiah Gray gets the start for tonight’s series opener, his first appearance in eight days. These are important outings for the young right-hander, who has run up a higher innings count than he ever has in his professional career and is in danger of being shut down if he doesn’t show some encouraging signs here soon. Tonight would be a good time to begin that process.

The Nationals go up against Jesús Luzardo, their former prospect who was dealt to the Athletics way back in 2017 for Sean Doolittle and Ryan Madson and has experienced some ups and downs since then. The 24-year-old lefty is 12-18 with a 4.87 ERA overall in 57 career big league games, 3-7 with a 3.81 ERA in 14 starts this season. Luzardo is facing the Nats for the first time this year, but he went up against them three times in 2021 and gave up 14 runs in 13 innings.

Hunter Harvey had taken the mound 55 times in a big league game, and aside from perhaps the first time three years ago, he did so feeling like he was completely in control of the situation. Until the Nationals right-hander found himself jogging in from the bullpen during the fourth inning Tuesday night, tasked with pitching out of a jam created by starter Cory Abbott, against the Orioles team that drafted him in 2013 and gave him his first big league appearance in 2019.

“That was like debut adrenaline,” he said afterward. “It don’t come around very often.”

And he didn’t mean it in a positive way.

By the time he departed one inning later, Harvey had suffered through perhaps the worst of his 30 appearances with the Nats this season, giving up both the tying and go-ahead runs in what would end up a 4-3 loss. Making matters worse, the tying run came via the first home run he’s surrendered this year, and it just so happened to come off the bat of one of his best friends: Ryan Mountcastle.

After escaping the fourth-inning jam with one inherited runner scoring but his team’s lead intact, Harvey prepared to return for the fifth. He knew Mountcastle would be leading off, and both guys knew they were about to square off for the first time in an actual game after years of imagining just such a scenario.

The way they jumped out to an early lead, this felt like a night that would see the Nationals keep putting runners on base and keep threatening to add to that lead. Turns out they wouldn’t score again, and the one time they seriously threatened, their rookie shortstop ran himself out of the inning.

This 4-3 loss to the Orioles was frustrating, though for different reasons than many previous losses were. There was no bullpen meltdown. There was no critical defensive mistake. There was no disastrous outing by the starting pitcher.

Instead, this one-run loss saw the Nationals lineup go cold after the third inning, then botch its last best chance to tie the game when CJ Abrams tried to advance to third base on a ground ball right in front of him to kill a sixth-inning rally.

"He's young and wanting to get to third base, knew he had to get to third base," manager Davey Martinez said. "But that situation, you've got to see the ball through. You've got to get back to second and see what happens. It's just a young mistake. He knew right away: He should've gone back."

Abrams, whose play of late has mostly been sensational, led off the inning with a double to the gap in left-center, knocking Baltimore starter Dean Kremer from the game. But when reliever Dillon Tate immediately got Israel Pineda to hit a sharp grounder to short, Abams took off for third, an ill-advised gamble.

Luis García has excelled at his new position in the field. How will he handle a new position in the Nationals lineup?

García finds himself batting cleanup tonight for the first time in his career, penciled in by manager Davey Martinez as his No. 4 hitter for the Nats’ series opener against the Orioles.

It’s both a reflection of García's performance at the plate and the state of the rest of the lineup, which has seen Nelson Cruz struggle mightily and get bumped out of the cleanup spot, plus Keibert Ruiz land on the injured list likely for the remainder of the season.

“I wanted to try to break up our lineup with some of those righties and get him in there,” Martinez said. “He matches up well with (Orioles starter Dean Kremer) in there today. I thought we’ll give it a shot, see how he reacts to it. When he hits the ball, he hits it hard. I like the way he’s swinging the bat. So we’re going to put him at cleanup and see how he does.”

García has enjoyed a sustained stretch of success at the plate, batting .312 with four doubles, two homers, nine RBIs and an .809 OPS over his last 14 games. That coincides with his return from a minor groin strain and his move from shortstop to second base following CJ Abrams’ arrival from the Padres.

And we’re back at Nationals Park for the first time in 12 days. The Nats return to town following a long, three-city road trip that included series wins at New York and St. Louis but then a sweep in Philadelphia, which left a sour taste in everyone’s mouths. Now they begin a five-game homestand against the Orioles and Marlins as the final 21-game stretch of the season arrives.

The two interleague rivals split their two-game series at Camden Yards in June, one of those a rain-shorted loss. At that point, the Orioles were just starting to push their way into the American League postseason picture. They remain in the mix now, but they’ve taken a few steps back in the last week and enter this week 5 1/2 games behind the Rays for the final wild card berth.

Cory Abbott makes the start tonight as the Nationals give Josiah Gray and Paolo Espino extra rest before their next starts. The right-hander has done a solid-if-unspectacular job as a swingman, bouncing between the rotation and the bullpen. We’ll see how he does tonight against an emerging Baltimore lineup.

That was a long day at the end of a long road trip as the end of a long season approaches. The Nationals sat through a 3-hour, 36-minute rain delay Sunday afternoon before finally losing 7-5 to the Phillies to be swept at Citizens Bank Park. What was shaping up to be a nice 10-day road trip against nothing but National League contenders wound up ending on a sour note and a 4-6 record.

The Nats get a well-deserved day off before returning Tuesday night to face the Orioles in a quick, two-game interleague series before getting another day off Thursday, after which they'll face only NL East rivals the rest of the way.

There's plenty to discuss, though, so let's take some time this morning to answer your questions. As always, submit them in the comments section below, then check back for my replies throughout the morning ...

PHILADELPHIA – On the final day of a 10-game road trip, at the end of a ballgame that started more than seven hours earlier, the Nationals were left with an exhausted bullpen and a weekend sweep at the hands of a division rival that has owned them all year long.

Forced to take over in the third inning for starter Aníbal Sánchez thanks to a three-hour, 36-minute rain delay, the Nats bullpen was battered around by the Phillies during a 7-5 loss that tested the patience of anyone who dared sit through the entire affair.

A game that began at 1:08 p.m. ended at 8:12 p.m., that extra-long rain delay throwing a wrench into everyone’s Sunday plans when it commenced prior to the top of the third inning. With no more trips to Philadelphia on the Nationals’ schedule, and the Phillies very much in the National League wild card race, this game was going to be completed, no matter how long it took.

The rain was an annoyance for fans and players alike, but its most tangible impact on the game itself was the manner in which it knocked out both teams’ starters after only two innings and put added strain on the respective bullpens to pitch the rest of the afternoon and evening.

"It's a good thing we've got a day off tomorrow, so we get to regroup a little bit," manager Davey Martinez said. "That's a lot, but both teams went out there and we battled. A home run just got us in the seventh."

PHILADELPHIA – News and notes before the Nationals (hopefully) take the field for their series finale against the Phillies (provided the weather holds up) …

* Luis García is out of the lineup for the second straight day. Manager Davey Martinez said on Saturday the young second baseman was simply getting a breather and would be back for today’s game. But it turns out while taking swings in the cage Saturday, García didn’t feel right.

“He actually hit yesterday after we spoke, and he came up to the trainer and said his right side was sore,” Martinez said this morning. “So he got evaluated. They worked on him. I want to be extra careful, so we’ll give him today off. Then we’ve got a scheduled day off tomorrow. So we’ll see how he feels today and then tomorrow.”

With García out, the Nationals interestingly enough are having Ildemaro Vargas start at second base this afternoon, with César Hernández at third base. That’s the opposite alignment they used Saturday night, when both players were charged with throwing errors and Hernández made several other poor throws from second base.

“They’ve both played both positions,” Martinez said. “Give Vargas a day or two over at second base as well, just to see what that looks like. We’ve talked a lot about being versatile, so I want to get him over there. And César’s been playing third base well, so we just decided today we’ll switch it up.”

PHILADELPHIA – The forecast here is not good. It’s supposed to rain all day. The forecast tomorrow is somewhat better, though not guaranteed to be dry. That’s the only remaining common off-day for the Nationals and Phillies. In other words, this has the potential to be a mess, and we could be here for a while, then possibly coming back tomorrow.

Whenever they play, the Nationals will be trying to avoid a series sweep that would put a real damper on what had been shaping up to be their best road trip of the season. A win would at least allow them to head home with a 5-5 record.

To do that, Aníbal Sánchez is going to have to keep up his surprising resurgence (0.84 ERA, 0.797 WHIP over his last four starts) by keeping the ball in the yard. The Phillies have out-homered the Nats a staggering 32-9 in 14 head-to-head games this year.

The Nationals will be going up against Aaron Nola for the fourth time this season. The right-hander has a sparkling 1.66 ERA in the previous three starts, though his record is only 1-1.

PHILADELPHIA – For the past three weeks, the Nationals had been playing a much more watchable brand of baseball, made possible in large part by a vast improvement in the field.

Having spent the vast majority of the season trotting out the majors’ worst defense, the Nats have seen that problem area morph into a real strength since the arrival of 21-year-old shortstop CJ Abrams, which allowed Luis García to move to his more natural position at second base, while journeyman Ildemaro Vargas became a rock-solid addition at third base.

Then came tonight’s 8-5 loss at Citizens Bank Park, in which the Nationals reverted back to all their worst habits from this now 91-loss season, from poor starting pitching to a lack of sustained offense to unsightly defense.

The defensive miscues stood out more than anything else, because this team had looked so impressive in the field during their recent upswing. Officially, the Nats were charged with two errors (one by Vargas, one by César Hernández) but that doesn’t come close to telling the full story.

"Our infield didn't throw the ball well today," manager Davey Martinez said. "But they've been playing really well, so I'm just going to chalk it up to one of those nights, and come back tomorrow."

PHILADELPHIA – Some news and notes before the Nationals take on the Phillies in the second game of this weekend’s series at Citizens Bank Park …

* MacKenzie Gore is set to make a rehab start Sunday for Triple-A Rochester at Syracuse, his first game action since his acquisition from the Padres at the trade deadline.

Gore, who has been on the 15-day injured list with left elbow inflammation, is scheduled to throw three innings for the Red Wings, perhaps building up his pitch count to 45.

The Nationals are attempting to build Gore up enough to come off the IL before season’s end. Manager Davey Martinez said they’d ideally like for him to get up to five innings and 75 pitches, so that would suggest three minor league rehab starts and then at most two starts for the Nats in the season’s final days.

“The most exciting thing is that he’s throwing off the mound again. The ball’s coming out, and he looks like he’s good,” Martinez said. “Now it’s just a matter of facing hitters. We saw him do that a little bit, but now he gets to compete. I’m looking forward to watching him do that. My big thing is to make sure that when he leaves here this year, he’s healthy and he can go into the winter. And then we’ll build him up and get him ready for spring training.”

PHILADELPHIA – After coming up short in Friday night’s series opener, the Nationals try to rediscover their winning ways tonight at Citizens Bank Park. They’ll need a better start from Erick Fedde than they got from Patrick Corbin, who despite a ridiculously low pitch count still gave up five runs on 12 hits in 6 1/3 innings during a 5-3 loss to the Phillies.

Fedde is coming off a strong outing Sunday in New York, where he held the Mets to one run over six innings to beat them for the first time in 11 career head-to-head starts. The right-hander actually is facing the Phillies for the first time this season, an odd rotation scheduling quirk, and he’ll be going up against his old high school buddy Bryce Harper, who is merely 9-for-18 with five homers in his career against Fedde.

With left-hander Ranger Suárez starting for Philadelphia, Davey Martinez is going with a right-handed-heavy lineup. That includes Nelson Cruz batting cleanup again after hitting sixth on Thursday and then sitting Friday. It includes the suddenly potent Alex Call in the No. 5 spot, with César Hernández behind him and playing second base.

PHILADELPHIA – Keibert Ruiz’s first full big league season has likely come to an unfortunate end. But while everyone certainly would have liked to see him finish the year out on the active roster, to be honest, there wasn’t really anything else he needed to prove.

The Nationals know Ruiz can hit for contact. They know he has emerging power. They know he is developing into a more aggressive game planner and pitch caller. They know he’s got one of the best arms in baseball behind the plate. And they know he’s tough and durable, wanting to play as often as possible at the most physically demanding position in the sport.

What the Nats don’t know at this point is the identity of their No. 2 catcher heading into 2023.

They’ve alternated between Riley Adams and Tres Barrera this season, neither one of them showing enough consistency to seize the job on a permanent basis. And now they can add Israel Pineda to the mix after calling up the 22-year-old only one week after he was promoted from Double-A Harrisburg to Triple-A Rochester.

Manager Davey Martinez intends to get a good look at all three over the season’s final 23 games.

PHILADELPHIA – Patrick Corbin and Noah Syndergaard, at their best, were high-strikeout pitchers. Double-digit totals were regular occurrences for both starters, back when Corbin was leading the Nationals and Syndergaard was leading the Mets deep into Octobers of yesteryear.

That’s not who either guy is right now, Corbin because he’s devolved into a shell of his former self, Syndergaard because he missed considerable time with major arm injuries.

So when they faced off tonight at Citizens Bank Park, the fast-paced ballgame that ensued featured precious few strikeouts, zero walks by either starter and a whole lot of early contact by both lineups.

The Phillies managed to make more out of their contact than the Nationals did, emerging with a 5-3 victory that left Corbin to suffer his 18th loss of the season.

Corbin, who allowed five runs and a whopping 12 hits over 6 2/3 innings despite throwing only 69 pitches, is the majors’ first 18-game loser since Chris Archer and James Shields each lost 19 in 2016. Barring a change in the Nats’ rotation plans, he’s on track to make four more starts this year as he attempts to avoid becoming the sport’s first 20-game loser in nearly two decades.

PHILADELPHIA – Keibert Ruiz’s season has likely come to an abrupt end after the Nationals placed their young catcher on the injured list with a testicular contusion that forced him to remain in a St. Louis hospital overnight after he was struck by a foul ball during the team’s series finale against the Cardinals.

Ruiz was discharged and was flying to Philadelphia late this afternoon to rejoin the Nationals, who formally placed him on the 10-day IL prior to tonight’s game against the Phillies. Manager Davey Martinez, though, said Ruiz has been instructed not to partake in any strenuous activities for three weeks, which leaves him almost no chance of making it back before the season ends in 26 days.

“We hope that he just continues to get better,” Martinez said. “We’ll see how he’s doing. But with everything going on, the doctors said he’s not able to do anything strenuous for three weeks. So we’re just going to take it day by day and take it from there.”

Martinez generally was encouraged about Ruiz’s progress in the last day and didn’t sound overly concerned about his long-term well-being. Assuming his season is over, the 24-year-old will finish with a .251 batting average, 22 doubles, seven homers, 36 RBIs and a .673 OPS across 433 plate appearances.

Ruiz enters the day having caught 106 games, second only to the Phillies’ J.T. Realmuto this season. He has thrown out 18 basestealers while also picking off four runners, giving him 22 total runners thrown out (again, second only to Realmuto among all major league catchers).
