Two more injured Nationals relievers are ready to begin pitching in competitive games.

Tanner Rainey and Mason Thompson will both begin minor league rehab assignments Friday, manager Davey Martinez announced prior to tonight’s game against the Red Sox. Rainey will pitch for Single-A Fredericksburg, with Thompson joining Double-A Harrisburg, which is playing at Richmond this week.

For Rainey, this marks the most significant step in his long recovery from Tommy John surgery. The 30-year-old right-hander is more than a year removed from his procedure to replace the ulnar collateral ligament in his elbow, and though he has faced live hitters in West Palm Beach, Fla., and here at Nationals Park in recent days, he’s now ready to compete in an actual game.

The club wants Rainey to take things slow, recognizing he’s allotted up to 30 days on his rehab assignment before he must be added to the active roster. If things go, he’ll likely join the Nationals in mid-September and make a handful of appearances before season’s end.

“Just continue to remember where he’s at,” Martinez said. “And we’re still building up.”

So for the first time in a while, the Nationals did not mount a late rally Tuesday night. As such, they dropped their series opener to the Red Sox, 5-4, that score holding up from the fourth inning all the way through the ninth. They’ll look to bounce back tonight, whether taking and holding an early lead or rallying again, in the middle game of the interleague series.

After watching Josiah Gray record only nine outs Tuesday, Davey Martinez needed to use five relievers for six innings to finish out the game. So some length from MacKenzie Gore tonight would be very welcome if the left-hander can provide it. Like Gray, Gore has dealt with some high pitch counts and early exits. He’s also surrendered home runs, three of them in his last start against the Phillies.

The Red Sox also send a lefty to the mound in James Paxton, the veteran who hasn’t pitched much since 2019 due to injuries. Paxton has been good since returning healthy this season, though, with a 3.36 ERA in 15 starts. He just tossed 5 1/3 scoreless innings against the Royals last week.

Ask Davey Martinez to evaluate Josiah Gray’s recent struggles, and the Nationals manager doesn’t have to think for long before answering.

“The command of the fastball just hasn’t been there,” Martinez said following Tuesday night’s 5-4 loss to the Red Sox. “And he’s trying to rely on too many secondary pitches.”

If you want to boil Gray’s troubles down to a single diagnosis, that might well be it. He knows his fastball has been his least effective pitch since he reached the big leagues two years ago. But his occasional abandonment of it altogether only seems to lead to more trouble.

“We’ve got to get him to understand that the use of his fastball has got to be better,” Martinez said. “He’s really good when he throws his fastball down for strikes; it’s got some run to it. And then he can go to his secondary pitches. But his pitch count is getting way up there.”

Gray’s pitch count was astronomical Tuesday night. He needed 31 just to face five batters in the top of the first. He finished with a whopping 83 across only three-plus innings, averaging more than five thrown per batter faced.

The way things have been going around here lately, it was perfectly fair for anyone inside the Nationals dugout – or anywhere inside Nationals Park, for that matter – to reach the bottom of the ninth tonight and just assume the home team was going to rally once again and pull off another walk-off win.

So when it didn’t happen and the Red Sox were the ones congratulating each other following a 5-4 victory, nobody quite knew how to react.

Despite trailing by that same score since the fourth inning, the Nationals never could mount one final rally to get over the hump. They had walked off the Athletics both Saturday and Sunday. They could not walk off the Red Sox tonight.

"They were making good pitches," catcher Keibert Ruiz said. "Sometimes it's hard."

In the end, the Nationals were left to contemplate the latest abbreviated start by Josiah Gray, who labored more than he has in any previous outing and wound up surrendering all five runs Boston would score, all of them coming in the game’s first four innings.

Hunter Harvey believes he could’ve returned from his elbow strain at least a week ago, maybe sooner than that. Given the right-hander’s lengthy injury history, the Nationals weren’t about to rush him back from the 15-day injured list.

But once they saw him throwing 97-99 mph against live hitters over the weekend, there wasn’t much reason to wait any longer. So today the Nats activated Harvey off the IL and are eager to add him to a bullpen that still managed to dominate as a group in his absence the last three weeks.

“They’ve been great,” Harvey said. “I’ve heard (manager Davey Martinez) say guys needed to step up, and I think a lot of guys had a good opportunity and ran with it. … Everybody’s been pulling their weight, and it’s been good.”

Harvey first felt something wrong in his arm during the Nationals’ mid-July series in St. Louis and immediately spoke up, recognizing he hasn’t always been great at reporting physical ailments during his career. The team sent him home to get an MRI but was relieved to learn the injury wasn’t anything more serious.

Harvey was back throwing again within a week and was able to return without going on a minor league rehab assignment. His IL stint might’ve been even shorter, he believes, if his wife hadn’t given birth to their first son earlier than expected, drawing his undivided attention away from baseball.

It’s been a good stretch for the Nationals over the last several weeks, as we’ve outlined here. Now, can they keep it up against some postseason contenders? We’re about to find out with a run of series against the Red Sox, Phillies, Yankees, Marlins and Blue Jays.

It begins tonight against Boston, which enters play three games back in the American League wild card race, needing to get on a roll to catch Toronto and Seattle. So it’s a good test for Josiah Gray, who struggled to keep his pitch count down last week in Philadelphia and was knocked out after allowing four runs in only 4 2/3 innings.

The Nationals go up against a familiar face tonight. Well, not familiar to anyone who is still here, but familiar to anyone who knows their organizational history. Once upon a time (aka July 2015), Mike Rizzo traded a Single-A pitching prospect named Nick Pivetta to the Phillies for Jonathan Papelbon. We all know how that worked out, more so because of Papelbon’s tumultuous tenure here. Pivetta, now 30, makes his 147th career start tonight, owner of a 48-56 record and 4.92 ERA. He hasn’t been great, but he has lasted for a while in the big leagues.

The Nats have a familiar face back in their bullpen tonight: Hunter Harvey. The right-hander was activated off the 15-day injured list and will be available if needed. Joe La Sorsa was optioned to Triple-A Rochester to clear a spot for Harvey.

The Nationals, you may have heard, are playing winning baseball right now.

After a weekend sweep of the Athletics, they improved to 15-8 since July 21. They’re 19-12 since July 8, which is the best record in the National League East during that time, third-best in the NL.

Something clearly has to be going right for this team that wasn’t going right earlier in the season. Or last season. Or the season before that. But what exactly is going so right for them to cause such a dramatic turnaround?

You can find improvement in just about every aspect of play, from a lineup that is scoring more runs to a defense that is committing fewer errors to a bullpen that has dramatically become one of the most effective in the league in recent weeks. And all of that is true.

But if you really want to boil it all down to one key factor, here it is: The Nationals are winning the late innings.

Well, it was a rather interesting week here in NatsTown, was it not? It began with a sweep in Cincinnati. Then it included a no-hitter in Philadelphia. Then it concluded with another sweep over Oakland. All of a sudden, the Nationals have gone 19-12 since July 8, best in the NL East and third-best in the NL during that prolonged span.

Now another potentially momentous week awaits. There's a three-game series with the Red Sox beginning Tuesday. Then a three-game series with the Phillies that begins Friday in D.C. but concludes Sunday in Williamsport, Pa.

You've probably got questions about the current state of affairs around here, or maybe what the future has in store for the Nats, both short-term and long-term. If so, submit them in the comments section below and then check back throughout the morning for my responses ...

When Jeter Downs stepped to the plate to lead off the bottom of the ninth this afternoon, he had no realistic reason to believe he was about to jumpstart a game-winning rally.

The Nationals trailed the Athletics by five runs, having slogged their way through a mostly lifeless series finale that saw Trevor Williams get roughed up again while their lineup failed to deliver with runners in scoring position again. They would just have to accept a Sunday loss to Oakland but a weekend series victory.

But in the dugout, Dominic Smith was trying to keep his teammates engaged, no matter the score. “We’ve got three outs,” the first baseman told them. “Don’t give any at-bats away. They all matter.”

So by the time Downs somehow found himself stepping back to the plate some 25 minutes later, now with a chance to drive in the winning run, the young infielder had every reason in the world to believe he and his team were actually going to pull this thing off.

And when he delivered the final hit to cap a stunning, six-run rally, Downs could only soak in the moment as teammates mobbed him in the middle of the diamond following the most inexplicable, 8-7 victory most of them had ever experienced.

Though the depleted group has performed remarkably well in his absence, the Nationals bullpen is about to get one of its key members back.

Hunter Harvey, out the last four weeks with an elbow strain, is on track to come off the injured list early this week, according to manager Davey Martinez.

Harvey faced live hitters before Friday’s game at Nationals Park, then threw off the bullpen mound prior to today’s series finale against the Athletics. Barring any complications, the right-hander should be ready to come off the 15-day IL, foregoing a minor league rehab assignment.

“I think Hunter should be ready here in the next couple days,” Martinez said.

Ready for what?

Hello from Nationals Park. Yes, I’m back to work. In person. Many thanks to Bobby Blanco for jumping in to cover in my absence during what proved to be a very eventful week. And many thanks to all of you who offered well wishes while I was recovering from COVID.

The Nationals, as you know, are playing their best baseball of the year. Really, their best baseball in more than two years. They’ve gone 14-8 over the last 3 1/2 weeks, and today they have a chance at their third series sweep in that time, having already disposed of the Giants and Reds.

To do the same to the Athletics, they’ll need a bounce-back start from Trevor Williams, who was roughed up in Philadelphia on Tuesday to the tune of six runs and eight hits in only 4 2/3 innings. The home run has become Williams’ biggest problem; he enters today’s start having surrendered 25 of them this season, second-most in the National League.

The Nats lineup came through with two big hits during Saturday night’s win – Lane Thomas’ game-tying RBI single in the eighth, Keibert Ruiz’s walk-off homer in the ninth – but overall that group went 2-for-15 with runners in scoring position. That’s not usually a recipe for success. They’ll hope to convert in the clutch more this afternoon against A’s left-hander Ken Waldichuk, who enters with a 6.30 ERA and a whopping 5.2 walks issued per nine innings.

When the Nationals left Wrigley Field on July 19, they did so with a bullpen in shambles.

Hunter Harvey had just joined an injured list that already included Carl Edwards Jr. The rest of the group featured one established late-inning arm in Kyle Finnegan, a once-promising setup man now in the midst of massive slump in Mason Thompson and a bunch of other inexperienced and ineffective pitchers who had just endured through a nightmare of a series.

Over the course of their last two games against the Cubs, Nationals relievers had collectively surrendered 20 earned runs on 18 hits and seven walks in only 5 2/3 innings of work. They twice turned competitive, low-scoring games into lopsided blowouts.

At that point, all Davey Martinez could do was acknowledge the situation he was in, and hope things would improve with time and experience.

“They’re going to get another opportunity,” the manager insisted after an embarrassing 17-3 loss. “Many more opportunities. Hopefully they bounce back and learn from today.”

CINCINNATI – In order to sweep the Reds and win for the 11th time in their last 16 games overall, the Nationals merely needed to hit back-to-back homers on the first two pitches of the afternoon, then entrust an overworked, unproven, still-effective bullpen to hang on in one of baseball’s toughest pitchers’ parks.

When things are going your way, things are going your way. And they are most certainly going the Nats’ way right now.

Today’s 6-3 victory capped off an impressive weekend sweep at Great American Ball Park by an upstart visiting ballclub that made up for the sweep it suffered at the hands of the Reds last month in D.C. And it continued this club’s best sustained stretch in more than two years.

Owners of an 11-5 record since July 21, with sweeps of the Giants and Reds and a series win over the Brewers, the Nationals are giving themselves and their fans more reason to be optimistic than at any previous moment since the roster teardown and franchise rebuild began in July 2021. At 49-63 overall, they’re now on a 71-win pace that would represent a healthy 16-game improvement from last season’s 107-loss nadir.

"It's a long season. To do that consistently is hard," right fielder Lane Thomas told reporters afterward. "Otherwise, a lot of teams would do it. We've just got to keep doing what we're doing, and control what we can control. I think we do good things when we do that."

CINCINNATI – The Nationals cut ties with Paolo Espino today, requesting unconditional release waivers on the veteran right-hander in one of a series of transactions prior to their series finale against the Reds.

The Nats also reinstated Trevor Williams from bereavement leave and activated Israel Pineda off the 60-day injured list and subsequently optioned the now-healthy catcher to Double-A Harrisburg. They already had cleared a spot on the active roster for Williams, optioning reliever Amos Willingham to Triple-A Rochester following Saturday’s game. But they needed to make another move to open a spot on the 40-man roster for Pineda, and Espino was the unfortunate victim.

“It’s always hard, because I’ve known Paolo for quite some time now,” manager Davey Martinez told reporters at Great American Ball Park. “He’s done everything we’ve asked him to do. He’s been really good, a very positive guy. Working with these guys, getting to know them, getting to know their families, it’s always tough when you have to let them go.”

Espino was on the 15-day injured list with a sprain in his right ring finger after a ragged relief appearance in Chicago three weeks ago. In three big league games this season, the 36-year-old right-hander was charged with 11 runs and 14 hits in only four innings, a disappointing final act for what had been an uplifting story when he first joined the team.

A journeyman who had pitched for four different organizations from 2007-19 but appeared in only 12 major league games for the Brewers and Rangers during that time, Espino was called up from the Nationals in September 2020 to make two late-season appearances. He then was called up again in April 2021 to make a spot start for an injured Stephen Strasburg and wound up staying on the big league roster through the end of the 2022 season.

CINCINNATI – Well, well, well. Look at what we’ve got here. The Nationals have won 10 of 15 for the first time since June 2021. They’ve won four of their last five series, three of those coming against playoff contenders San Francisco, Milwaukee and Cincinnati. And they have a chance today to pull off their second three-game sweep in less than a month, if they can beat the Reds one more time.

Jake Irvin gets the start, facing the same Cincinnati club he held to three runs over six innings last month in D.C. The rookie right-hander continues to give his team a chance most times he takes the ball, even if his 4.86 ERA doesn’t exactly scream high-quality. Davey Martinez is probably going to need some length from Irvin today, because the back end of his bullpen may be burned up and unavailable, with Kyle Finnegan, Jordan Weems and Andrés Machado each having pitched each of the last two days.

It would help, then, if the Nationals lineup can score runs in bunches and provide some cushion for the pitching staff. That group will be facing an unfamiliar foe today in Lyon Richardson, a 23-year-old right-hander making his major league debut. A second-round pick in 2018, Richardson missed all of last season following Tommy John surgery. He burst through the Reds organization this year, producing a 1.86 ERA and a whopping 81 strikeouts in only 58 innings across three levels of the minors. But he made only one start at Triple-A before getting this promotion, and he has yet to pitch more than four innings at a time. So look for the Reds to pull him early, regardless of the result, and go to their bullpen.

CINCINNATI – Only once in his major league career had Joan Adon looked anything like this. It wasn’t in his two relief appearances earlier this season. It wasn’t in any of his 14 starts last season, 12 of which ended in a loss.

No, you have to go all the way back to Adon’s major league debut on the final day of the 2021 season to find any outing that resembled today’s performance by the young Nationals right-hander.

On that day, best remembered as the final day of Ryan Zimmerman’s storied career, Adon took the mound at Nationals Park, stared down a potent Red Sox club that needed to win to make the postseason and caught everyone by surprise with an eye-opening performance.

Nearly two years and a lot of disappointing starts later, Adon rediscovered his prime form today during a 7-3 victory over the Reds at Great American Ball Park. And then dialed it up a few more notches to put together the best outing of his brief career.

With both power and precision, the 24-year-old carried a perfect game into the sixth inning before the Reds finally got to him. No matter, because thanks to early run support from his teammates and lights-out work from his bullpen, Adon still emerged at the end of the day with only his second major league win.

CINCINNATI – The Nationals added another reliever to the injured list today, placing Mason Thompson on the 15-day IL with a left knee contusion that appears to have prevented the right-hander from pitching most of the week.

Thompson hadn’t appeared in a game since Monday, when he tossed a scoreless eighth on all of five pitches, helping lead the Nats to a 5-3 win over the Brewers. Despite the team being in several close games since then, manager Davey Martinez did not call upon his top setup man.

Martinez revealed Thompson recently hurt himself after falling, though he did not offer any more specifics than that.

“I don’t know how he fell, but he said he fell and he’s been dealing with it for a few days,” Martinez told reporters before today's game against the Reds. “Hopefully it will go away. He had an MRI that showed he had a contusion. So we’re going to make sure we take care of him and get him ready to go again.”

Though it has been five days since Thompson last pitched, IL moves can only be backdated three days. So he officially goes on the IL on Aug. 2 and will eligible to return Aug. 17.

CINCINNATI – Don’t look now, but the Nationals are playing some pretty good baseball. Seriously. They’ve won nine of their last 14 games, and they’re 19-16 since June 24, when they opened up a solid West Coast trip in San Diego and Seattle. That’s actually the sixth-best record in the National League during that time frame, 11th-best in the majors.

They’ll look to keep the good vibes going tonight and capture another series against a quality opponent if they can defeat the Reds again, though they’ll do so with something of a surprise starter on the mound: Joan Adon.

This was supposed to be Trevor Williams’ turn in the rotation, but the right-hander isn’t expected back from bereavement leave until Sunday, so the team needed a fill-in for this game. That fill-in is Adon, who makes his first big league start of the season, his third overall appearance. The 24-year-old right-hander wasn’t exactly tearing it up at Triple-A Rochester (3-5, 4.62 ERA, 1.506 WHIP in 17 starts) but his strikeout numbers of late (13 in his last 11 innings) have been good, so maybe that’s a sign of something.

The Nationals face a good young left-hander in rookie Andrew Abbott, a University of Virginia alum who enters with a 6-2 record, 2.35 ERA and 1.031 WHIP over his first 11 big league starts. Davey Martinez counters with a right-handed-heavy lineup that includes Joey Meneses at first base, Keibert Ruiz as DH, Riley Adams behind the plate and Stone Garrett in left field.

One other note: To clear a spot on the active roster for Adon, the Nats placed Mason Thompson on the 15-day injured list with a left knee contusion. The reliever hadn’t pitched since Monday, but IL moves can only be backdated three days, so that means he’s eligible to return Aug. 17.

CINCINNATI – Blake Rutherford initially figured he’d make his major league debut for the team that used its first-round draft pick on him in 2016: the Yankees. When he was part of a significant trade one year later, he assumed his debut would now come for the club that acquired him: the White Sox.

So imagine what must’ve been going through Rutherford’s mind Friday night when he took the field at Great American Ball Park, making his long-awaited major league debut not for the Yankees, not for the White Sox but for the Nationals.

“A lot of emotions,” the 26-year-old admitted. “A lot of people to thank. A lot of special people in my life that allowed me to get to this moment.”

The path may have been longer and more winding than he imagined when he became a professional seven years ago, but that didn’t make the end result any less sweet for Rutherford. He’s a big leaguer now, promoted by the Nationals and thrust into their starting lineup in left field for Friday’s series opener against the Reds after veteran Corey Dickerson was released.

Rutherford was a top-50 prospect in the sport back in 2017, the 18th overall pick in the draft by the Yankees out of his Southern California high school. And he was highly touted enough to be part of a four-player package (including Tyler Clippard) the Yankees sent to the White Sox in a July 2017 trade for Todd Frazier, David Robertson and Tommy Kahnle.

CINCINNATI – The Nationals, as anyone who has watched them all season knows, don’t hit home runs. The Reds, as anyone who has watched them in recent months knows, try to win games less with power and more with speed.

So wouldn’t you know all but one run scored in tonight’s series opener at Great American Ball Park came via the long ball. Including some really big ones from two of the Nats’ most important hitters.

Lane Thomas and Joey Meneses combined to launch three homers from the sixth through 10th innings, with Thomas’ second blast of the night serving as the final blow in the Nationals’ come-from-behind, 6-3 victory in extras.

Jake Alu’s latest clutch hit, an RBI double over the first baseman’s head, drove home automatic runner Ildemaro Vargas with the go-ahead run off Cincinnati closer Alexis Díaz. It was Alu’s third RBI in as many days since his promotion from Triple-A Rochester to replace traded third baseman Jeimer Candelario.

"He gives himself a chance," manager Davey Martinez told reporters afterward. "He battles up there. Even though he gets to two strikes, he battles and battles and battles until he gets a pitch to hit. Does a great job of moving the guys over, then driving them in."
