There are few surer things in baseball right now than David Peterson mowing down the Washington Nationals.

Stick the Mets left-hander on the mound against this particular lineup, and you probably know the results before he ever throws a pitch. Just let Peterson throw his tantalizing assortment of 90 mph sinkers, breaking balls and changeups and watch as the Nats continue to flail away, making precious little solid contact.

It’s happened before. It happened again tonight. And unless the Nationals’ position players actually do something to adjust, it’s pretty much guaranteed to happen again the next time they meet.

Tonight’s 8-1 loss might have stood out if not for the fact it was a near-repeat of Peterson’s last start against the Nats, when he tossed a six-hit shutout at Citi Field.

They didn’t score off him the time before that, either. All told, Peterson had thrown 25 consecutive scoreless innings against the Nationals before they finally broke through in the bottom of the eighth tonight. And the dominance isn’t confined to this current inexperienced lineup. During a career that began in 2020, Peterson has now faced the Nats a total of 14 times (11 of them starts). The Mets’ record in those games: 13-1.

Andrés Chaparro’s last stint with the Nationals didn’t include much playing time, to put it mildly. He appeared in only four games during three weeks on the big league roster in June.

This time around, there should be considerably more at-bats for the 26-year-old first baseman/designated hitter, who was recalled from Triple-A Rochester in a roster swap with infielder José Tena.

“He’s going to be playing against left-handed pitchers,” interim manager Miguel Cairo said. “I’m going to try to mix it up. It depends how he does. But we want to see him, and he should have an opportunity to show what he can do.”

Sure enough, Chaparro is in tonight’s lineup against Mets left-hander David Peterson, batting seventh and starting at first base, with Josh Bell back in the DH role after several starts at first base over the weekend.

The Nats saw glimpses of Chaparro’s production late last season, when he totaled 12 doubles and four homers in 33 games. But he went just 1-for-11 in his earlier stint this summer, stuck on the bench behind both Bell and Nathaniel Lowe.

As the Nationals took the field for batting practice Friday afternoon, Miguel Cairo motioned to Keibert Ruiz and José Tena to come join him at first base. To field grounders. And make some throws. And learn a little bit about a position neither of them has ever played before in a game.

It made for quite the scene, both because the 51-year-old interim manager was showing off his own still-solid glove skills and because the sight of Ruiz at something other than the catcher’s position made for an obvious question: Are the Nats thinking about moving him to first base at some point?

“No, no, no. It’s nothing like we’re planning to do it,” Ruiz said today.

As the 27-year-old catcher, out since early July with a concussion, explained: This is a way for him to get some on-field activity without putting himself at risk of further health problems. From a psychological standpoint, doctors have told him to try to stay engaged and react to baseball movements without thinking about the concussion.

“Kind of to put your mind away from: ‘Oh, I have to be careful,’” Ruiz said. “It’s nothing like I’m going to play first base now.”

That the Nationals found themselves in a position to win tonight’s game against the Phillies was a testament to MacKenzie Gore’s intestinal fortitude over six gutsy innings and the lineup’s ability to actually make Zack Wheeler work enough to knock him out after only five.

These two division rivals, residing at opposite ends of the NL East, were tied heading into the seventh before a boisterous, Friday night crowd of 35,143. It was about as much as the Nats could have asked for under the circumstances.

The problem: A Nationals bullpen that causes heartburn even when at full strength was without its two most reliable arms. So what happened next couldn’t have shocked anyone in the building, especially when considering the opponent.

Back-to-back home runs by Kyle Schwarber and Bryce Harper off Konnor Pilkington flipped the game in the top of the seventh, the Phillies’ big boys taking down a rookie member of the Nats’ relief corps en route to a 6-2 victory on a steamy August evening in Navy Yard.

"Look, you know you've got to play well against that team. Because if you don't, they can beat you up," Gore said. "I think just understanding that going in ... a tough loss tonight, but I think we all did a good job of that."

As the latter stages of Thursday night’s game was playing out, Cole Henry started to get the sense he was going to be the man holding the ball for the top of the ninth.

With interim manager Miguel Cairo using new closer Jose A. Ferrer to face the heart of the Phillies lineup with a one-run lead in the eighth, Henry was told by bullpen coach Ricky Bones to prep himself to pitch the ninth for the first time in his career.

“I was just preparing mentally,” the rookie reliever said. “And hopefully whenever they call the phone, it was gonna be me to do it.”

A few tense minutes later, Henry was pounding his glove in celebration, his teammates gathering at the mound as the stadium lights at Nationals Park turned red to commemorate the team’s 3-2 victory, the 26-year-old having notched his first career save in the process.

It wasn’t a perfectly clean inning. Henry surrendered a leadoff single to Max Kepler, then saw him advance to third base on a sacrifice bunt and a ground ball to the right side. That left the tying run 90 feet with Trea Turner at the plate. With the crowd standing, Henry won an eight-pitch battle with the former Nats star shortstop, striking him out on a sinker that ran way in on his hands and left Turner helplessly flailing at it.

The Nationals sent a message when they designated struggling first baseman Nathaniel Lowe for assignment this afternoon to make room for Dylan Crews’s return: "We want to see the young kids. ... We want to see what they can do,” said interim manager Miguel Cairo ahead of tonight’s four-game series opener against the Phillies.

Sure enough, Cairo started four of his five young outfielders, with James Wood serving as the designated hitter, Daylen Lile playing left field, Jacob Young in center and Crews back in right.

But it was another young player Cairo chose to start tonight that came up clutch for the Nats against this veteran Phillies squad in a 3-2 comeback victory in front of an announced crowd of 21,609 on South Capitol Street.

“I gotta tell you, that's a game that you look at it and it's like a playoff game," Cairo said after the win. "That's the way you play games like this. Good pitching, good defense, opportune hitting. It was nice to see our pitchers, our defense, our hitters really engage in the game and doing the little things. That's what we did today. They picked each other up.”

Of the five young outfielders, three of them are left-handed hitters, so one of them figured to sit to start this one. The odd-man out was Robert Hassell III. And Cairo also figured this was a good time to give shortstop CJ Abrams a breather after he played 24 straight games and with tough left-hander Jesús Luzardo starting for the visitors. So Paul DeJong started at shortstop and José Tena started at second base for just his fifth appearance since being recalled from Triple-A Rochester 2 ½ weeks ago.

The Nationals had a decision to make this afternoon as they prepared to reinstate Dylan Crews from the 60-day injured list. Do they send one of their four young outfielders – James Wood, Jacob Young, Robert Hassell III or Daylen Lile – down to Triple-A Rochester to get regular playing time? Or do they hold onto five outfielders and send down infielder José Tena, who has only played in four games since he was recalled 2 ½ weeks ago?

In the end, the Nats surprisingly went an entirely different route by designating struggling first baseman Nathaniel Lowe for assignment to make room for Crews, who returns after almost three months while dealing with a left oblique strain.

“We feel like we want to see the young kids,” interim manager Miguel Cairo said of the decision before tonight’s series opener against the Phillies. “We want to keep Hassell in the outfield, Lile, we have Wood. We have young players and I think we want to see them play. We want to see what they can do in the last month, month and a half.”

Lowe was acquired by former general manager Mike Rizzo in a December trade with the Rangers in exchange for left-handed reliever Robert Garcia. With two more years of arbitration eligibility, Lowe lost his salary arbitration case against the team and received a $10.3 million salary (the Nats’ highest-paid player this season) rather than the $11.1 million he requested.

The 30-year-old’s first half of the season was somewhat of a mixed bag. While he was on pace to be one of the team leaders in home runs and RBIs, his batting average, OPS and defensive metrics were well below his career averages.

KANSAS CITY, Mo. – The five-run top of the first – not to mention the extra runs scored in the third and fourth innings – should have been enough to make Miguel Cairo’s afternoon easy. But as Jake Irvin labored himself to keep that big lead intact, it became apparent the Nationals’ interim manager was going to have to play every pitching card he had available to him in an attempt to win today’s series finale against the Royals.

And then it was still going to require some more late offense to pull this one off.

It wasn’t always pretty, but the Nats did find a way to escape Kauffman Stadium with an 8-7 victory, one made possible by Daylen Lile’s game-winning single in the top of the ninth and five relievers combining to allow just one run over five innings.

"They've been ready, they've been settling down. They're doing an excellent job," said Cairo of a relief corps that has been turned over several times this season and currently includes seven rookies alongside 25-year-old closer Jose A. Ferrer. "Today, it was a team effort: Offense, pitching. That's what we're asking."

Lile’s clutch hit came a few minutes after the Royals tied the game against unlikely setup man Clayton Beeter. Luis García Jr. ignited the rally with a one-out double off Kansas City’s Carlos Estévez, then took third on Josh Bell’s flyout to center. Two batters later, Lile got to a 2-1 changeup from Estévez and lined the ball to right field for the go-ahead single.

KANSAS CITY, Mo. – The emotions of his long-awaited return to the majors behind him at last, Cade Cavalli settled into life as a true big league pitcher tonight, taking the mound for his second start, confident he will be back out there for his third and plenty more before season’s end.

This one didn’t have the fairy tale ending last week’s return did.

Missing the precise command of his eye-popping arsenal he displayed against the Athletics, Cavalli was charged with four runs in five-plus innings tonight against the Royals, giving up a killer, game-tying homer to Salvador Perez before departing in the sixth.

Jackson Rutledge then gave up the game-winning homer, a two-run blast by No. 9 hitter Kyle Isbel that propelled Kansas City to an eventual 7-4 victory over the Nationals.

Given an opportunity to appear in a high-leverage spot in a tie game, Rutledge got a key double-play grounder but then allowed a two-out single to Nick Loftin before leaving a 2-1 sinker over the plate to Isbel, who launched it deep to right for the decisive moment of the game. (The Royals added an insurance run in the eighth off Orlando Ribalta.)

KANSAS CITY, Mo. – Though he has played the full nine innings on back-to-back days for Triple-A Rochester, Dylan Crews will remain on his minor league rehab assignment for now.

Crews is staying with the Red Wings, who are off today, the Nationals announced. He’s then scheduled to play the outfield again Tuesday and Wednesday in Rochester against Syracuse.

Those will be Crews’ 12th and 13th games played on this rehab assignment, a longer stint than most injured major league position players typically serve. The Nats, though, want to see the 23-year-old not only prove he’s healthy but that he’s consistently productive at the plate again before they intend to activate him off the 60-day injured list.

Out since he strained his left oblique muscle on a May 20 check-swing, Crews began his rehab assignment with Rochester on July 29. The plan was to slowly build up his workload until he was able to play nine innings in the field on back-to-back days. He did that for the first time this weekend, playing all nine innings in right field both Saturday and Sunday at Norfolk.

Crews’ offensive production has been decent – he’s 10-for-36 with a double, two homers, seven RBIs, one walk and six strikeouts in 11 games – but the Nats appear to want to see more still before they deem him big league-ready again.

SAN FRANCISCO – Maybe it was the cool air blowing out towards the bay, the clear blue sky welcoming everyone to summer in San Francisco. Maybe it was just time for things to stabilize again for a Nationals team that looked lost, defeated and deflated in its first week following a tumultuous trade deadline.

Whatever the case, back-to-back day games at Oracle Park provided the recipe for a much-needed, get-right weekend for the Nats, especially their biggest stars.

Today’s 8-0 thumping of the Giants saw MacKenzie Gore look like MacKenzie Gore again, the left-hander striking out 10 over six scoreless innings to bounce back from a wretched stretch of four substandard starts.

It saw CJ Abrams look like CJ Abrams again, the shortstop launching a two-run homer off the right field foul pole, then singling and scoring again later.

And along with Saturday’s 4-2 win, James Wood looked like James Wood again, the slumping slugger recording a homer and three doubles to drive in six runs (four of them coming during today’s game).

SAN FRANCISCO – When Cole Henry loaded the bases with one out in the bottom of the eighth Saturday afternoon, Miguel Cairo could have stuck with his rookie setup man and given him a chance to pitch his way out of the jam. The Nationals led by three runs. There was at least some margin for error.

Cairo, though, didn’t hesitate to walk straight to the mound and hold his left arm out, signaling toward the bullpen in right-center. He wanted the lefty. He wanted Jose A. Ferrer, even if he was now asking his newly anointed closer to produce a five-out save before ever recording a simple three-out one.

“I was just like: I’ve got to worry about today. I cannot worry about tomorrow,” the interim manager said. “That was the best matchup. Their good hitters were coming up. I’ll just take my chances with him.”

Ferrer proceeded to reward his manager’s faith in him and make his first save since replacing Kyle Finnegan a memorable one. He allowed one of the three inherited runners to score via Wilmer Flores’ sacrifice fly. But he struck out Matt Chapman with a 99 mph fastball to end the eighth. Then he pitched out of another jam in the ninth, inducing a game-ending double play out of Patrick Bailey to lock up the Nats’ 4-2 win.

It had been nine days since the Nationals dealt Finnegan to the Tigers at the trade deadline, eight days since Cairo coyly refused to name his new closer, noting the world would find out once he was in a situation to use him.

This homestand has not been kind to the Nationals' offense. Over the first five games, they only scored 23 runs, 11 of which came in the ninth inning.

One of those ninth-inning runs, however, was last night’s walk-off winner to snap a six-game losing streak. The Nats were hopeful those good vibes would carry over into Thursday’s matinee finale as they went for a much-needed series win over the Athletics.

But the early hole the Nats found themselves in this afternoon was too much for this lifeless lineup to overcome in a 6-0 loss in front of an announced crowd of 14,519 on South Capitol Street.

Interim manager Miguel Cairo tried to go against conventional wisdom against A’s left-hander Jacob Lopez. Instead of stacking his order with right-handed hitters, like most teams have against Lopez this year (only 52 plate appearances by left-handed hitters against him entering today), Cairo put six lefties in his starting lineup, leaving two switch-hitters (Josh Bell and Drew Millas) and one right-hander (Brady House) on the bench.

“House has not been hitting good against lefties," Cairo said to explain his lineup after the game. "I wanted (Paul) DeJong, he's been swinging the bat good. JB right-handed, he's not swinging the back good either. He's a better left-handed hitter. So I was just trying to go with giving a chance to (Luis García Jr.) to play second base to see if he can do a better job. But I guess I gotta do a better job doing the lineup against lefties.”

When Shinnosuke Ogasawara signed a two-year, $3.5 million contract with the Nationals in January, not only did he become the first player the organization signed directly from Asia, but he also became an instant contender for a starting rotation spot.

But that didn’t come to fruition in spring training, as he was optioned to start the season at Triple-A Rochester.

The 27-year-old left-hander was called up to make his major league debut on July 6, completing only 2 ⅔ innings and giving up four runs and seven hits in a loss to the Red Sox. His second start was better, but he still gave up three runs and four hits in just four innings against the Brewers.

The Nats optioned Ogasawara back to Rochester following that start, deciding to instead fill his rotation spot with Brad Lord after the All-Star break. But with holes left on the roster following the trade deadline, the club brought him back to the major leagues to take on a role in the bullpen.

Since then, Ogasawara has found the results he and the team had hoped for back in camp.

As the hits kept on coming, one after another, MacKenzie Gore stood on the mound with a look on his face that suggested anger, frustration and bewilderment all wrapped up in one.

The Nationals ace, an All-Star just a few weeks ago, the majors’ strikeout leader just a month ago, had faced six Athletics batters to open tonight’s game. Five of them had scored, all five of them having recorded base hits, two of them home runs.

Before having a chance to come up to bat themselves, the Nats already were well on their way to a 16-7 loss, yet another in a string of unsightly, lopsided August losses that have somehow made the disasters that were June and July look tame in comparison.

The Nationals have lost six in a row, the combined score of those games a jaw-dropping 70-26. They've lost the first four games of this homestand 54-20, and that doesn't tell the full story because 11 of the runs they've scored have come in the ninth inning of games that were already well out of hand.

"This is embarrassing," Gore said. "We shouldn't just try to act like nothing happened here. What has happened this homestand is not acceptable, no matter what happened last week. We're all better than this. This is embarrassing. We've got to not let it affect everybody. We've got to be able to come together as a group and get better. What happened this homestand, it's hard to watch."

The revolving door that has been the 2025 Nationals bullpen picked up two new passengers today when the club added Clayton Beeter and PJ Poulin to the major league roster, two recent acquisitions who are going to get a chance to contribute to a relief corps that needs all the help it can get.

After trading veterans Kyle Finnegan, Andrew Chafin and Luis Garcia prior to last week’s deadline, the Nats were left with a highly inexperienced bullpen with only one member who had pitched in more than 45 big league games in his career (Jose A. Ferrer). That group was promptly battered around by the Brewers, surrendering 22 runs (19 earned) on 30 hits and nine walks across 14 1/3 innings during their weekend sweep, leading to the demotions of Ryan Loutos and Zach Brzykcy to Triple-A Rochester.

Enter Beeter (one of two prospects acquired from the Yankees for Amed Rosario) and Poulin (claimed off waivers from the Tigers on Sunday).

“I believe we need a lefty, and we just claimed (Poulin) off waivers,” interim manager Miguel Cairo said. “Beeter, he throws hard, good slider. And I’m looking forward to seeing how he matches up with big league hitters.”

Beeter, 26, has a little bit of major league experience, appearing in five games for the Yankees across the last two seasons. A second-round pick in 2020 from Texas Tech, he spent most of his minor league career as a starter before moving to the bullpen this season. In 18 games with Triple-A Scranton/Wilkes-Barre after time on the injured list with a shoulder impingement, he produced a 3.10 ERA, striking out 33 batters in only 20 1/3 innings (albeit with 16 walks issued in that same time frame).

No matter if and when the Nationals' offense showed up today against the Brewers, the pitching simply needed to be better.

After allowing 16 runs and giving up a club-record 25 hits in Friday’s series-opening loss, the collective effort on the mound had to drastically improve for the home team or else they again would have no shot to beat the team with the best record in baseball.

Leading that charge on the hill was Jake Irvin, who was looking to follow up his strong outing his last time out in his home state of Minnesota. But the right-hander surrendered an early lead en route to another short outing in the Nats’ 8-2 loss in front of 28,869 fans on South Capitol Street.

Before he tossed seven strong innings of two-run ball against the Twins, Irvin turned in his shortest start of the season against the Reds, giving up five runs in just 3 ⅔ innings on 72 pitches. He just barely eclipsed that Saturday afternoon.

The Brewers were all over Irvin from the jump, their lineup filled with lefties and switch-hitters who were easily pulling his pitches into right field. They ended up scoring in each of the first three frames to put the Nats in an early hole.

Keibert Ruiz walked around the Nationals' clubhouse with his usual big smile. He then had a playful interaction with CJ Abrams walking from his locker to the kitchen. All seemed normal.

Except life is still not normal for the 27-year-old catcher, who continues to experience symptoms from a concussion that has placed him on the injured list twice since June 24 and most recently since July 8.

“I feel much better than a couple weeks ago,” Ruiz said at his locker before today’s game against the Brewers. “And I'm just following the protocol. I gotta get used to noises and I'm sensitive. ... I'm doing a little bit more every day, like working out and all that stuff.”

Ruiz missed 10 days during his first IL stint after he was hit in the head by a ricocheting foul ball in the visitors’ dugout in San Diego. In just his second game back, he was struck in the facemask by two foul balls, which brought back the concussion symptoms.

The Nats chose to place him back on the IL the following day with the same concussion that had been reaggravated. Since then, Ruiz has barely been around the team, not traveling with them on road trips and not coming around the home clubhouse while trying to get his sensitivity to light and noises down.

The post-trade-deadline portion of the 2025 Nationals season began tonight with a dud that neither offered much new hope for an August bounceback nor answered one of the great unknown questions now confronting this team: Who’s the closer now?

Interim manager Miguel Cairo chose to keep that information private when asked this afternoon, promising we’ll all find out together the next time the Nats take a lead into the ninth inning. It certainly didn’t happen tonight during a 16-9 thumping at the hands of the Brewers that felt like it was decided by the middle of the third, with the home team scoring five runs in the ninth to make it look a bit closer.

Mitchell Parker was battered around by the same Milwaukee lineup that put a hurting on him earlier this month at American Family Field, the left-hander charged with eight runs on 12 hits in four-plus innings.

That left the remnants of a Nationals bullpen that lost its three most reliable arms in the last 48 hours to cobble together five innings before this game could be completed. The four relievers who pitched tonight collectively gave up eight runs of their own to turn this one into a complete laugher (aside from those in the crowd of 25,194 who booed during the later innings).

The 25 hits allowed by the Nats shattered the previous club record of 22, set on five different occasions over the last two decades.

HOUSTON – The Nationals’ final ballgame before the 2025 trade deadline offered a stark reminder why they’re in full-scale sell mode for the fifth straight year.

Despite the presence of their ace on the mound and an unaccomplished rookie starting for the opposition, the Nats were roughed up by the Astros during a 9-1 blowout loss that saw MacKenzie Gore’s recent struggles continue and interim manager Miguel Cairo get ejected for the first time.

Gore, whose name has emerged as a potential trade candidate – more so by contenders interested in acquiring an All-Star lefty with two-plus years of club control than by the Nationals themselves – this month, endured through his third consecutive shaky outing, this one bringing out some negative emotions from the 26-year-old.

Gore was charged with six runs in 5 1/3 innings, surrendering a pair of homers while also seeing his command go awry at times. He has now allowed 15 runs while walking 10 batters over his last 12 2/3 innings, during which time his ERA has jumped from 3.02 to 3.80.

Whether any potentially interested contenders view these recent struggles as reason to reduce their offers to interim general manager Mike DeBartolo in advance of Thursday night’s trade deadline remains to be seen. Either way, Gore unquestionably is now mired in the worst stretch of an otherwise fantastic season.
