SEATTLE – A Nationals bullpen that has gone through a number of changes in the last week experienced another one today when the club promoted right-hander Amos Willingham from Triple-A and optioned Paolo Espino back to Rochester.

This move comes only two days after the Nats called Espino up to replace Chad Kuhl, who was designated for assignment. (The club officially requested unconditional release waivers on Kuhl today, making him a free agent.)

Willingham, 24, made a name for himself in the organization early this season, stringing together 10 consecutive scoreless appearances with 14 strikeouts and only one walk for Double-A Harrisburg. That earned him a promotion last month to Triple-A, where he wasn’t as dominant (3.46 ERA, 11 strikeouts, eight walks over 13 innings), but still pitched well enough to earn consideration for another promotion.

“I knew this could be a big year for me,” he said. “I needed to go in and take care of everything I needed to do, and I knew there would be opportunities to move up. I had no idea it would happen this fast. I was thinking at this point in the year maybe get to Triple-A, and then maybe be in Triple-A until September and maybe get a look up here. But it’s all happened so fast, it’s hard to really fathom the entire process.”

The Nationals might have called Willingham up Saturday to take Kuhl’s spot, but he had just thrown 30 pitches over two innings and likely wouldn’t have been available for another couple days. So they instead recalled Espino, who wound up pitching the ninth inning of Sunday’s 8-3 win in San Diego but retired only two of the five batters he faced, prompting manager Davey Martinez to summon closer Hunter Harvey for the final out.

The Nationals continue to do enough to keep themselves engaged in close ballgames, right through the final out of the ninth. And they continue to do just enough to keep themselves from emerging victorious by losing the second half of close ballgames.

Whether by bullpen struggle or punchless lineup, the Nats just aren’t delivering in meaningful situations when they have a chance to seize control of a game late. It’s happened several times over the last two-plus weeks, and it happened again this evening during a 6-4 loss to the Guardians that was there for the taking but never captured by the home club.

The Nationals’ 11th loss in their first 15 games followed an all-too-familiar script. They had a brief burst of offense early, scoring three runs in the bottom of the first. Then they let the opposition catch up and then overtake them by the top of the fifth. And then they did very little at the plate themselves the rest of the way, shut down by Cleveland’s bullpen to suffer yet another loss by slim margin.

Four of the Nats’ last six losses have come by only one run. The others were a 2-0 defeat at the hands of Shohei Ohtani on Tuesday night in Anaheim, then this two-run loss that had been a one-run game until Josh Bell produced a big insurance run for the Guardians in the top of the ninth.

The common theme in all of these losses: A lack of execution in the later innings. Entering tonight, the Nationals owned a solid .751 OPS in innings 1-3, a respectable .702 OPS in innings 4-6 but a paltry .486 OPS in innings 7-9.

The Nationals are losing more far more games than they win right now. But those losses all have been close. Four of their last five defeats have come by one run, including Friday night’s 4-3 margin to the Guardians. And the other was a 2-0 loss to Shohei Ohtani.

So they’ll try to reverse that trend this afternoon in the second game of the weekend series, hoping perhaps their lineup can actually sustain something throughout the game instead of settling for a few early runs and then shutting down the rest of the way. They'll face right-hander Zach Plesac, who was roughed up by the Athletics in his season debut but then pitched seven strong innings against the Mariners his next time out. So who knows what to expect today?

Chad Kuhl becomes the final member of the Nats rotation to make his third start of the season. The right-hander gave his team a chance last time out in Colorado, getting through five innings allowing three runs, but then he faded quick in the sixth and wound up with two more runs charged to his name. Given how much the “A” bullpen has been used, particularly Friday night, it’ll be interesting to see if Davey Martinez tries to push Kuhl into the sixth again if the situation arises.

It’s Jackie Robinson Day across all of Major League Baseball, so both teams will be wearing No. 42 jerseys. That can make for some confusion among broadcasters and reporters trying to figure out who’s who, but obviously it’s for good reason.

DENVER – It’s hard to call a six-run offensive performance unsatisfactory, especially for a lineup that hasn’t exactly been great at scoring runs so far this season. The usual standards of offensive success, though, don’t always apply 5,280 feet above sea level.

The Nationals, sorry to say, needed more than that this afternoon during a 7-6 loss to the Rockies at Coors Field. Maybe that’s more an indictment of their bullpen, which saw four runs cross the plate in the bottom of the sixth under its watch. But with several top relief arms unavailable after contributing to wins both Friday and Saturday nights, it was always going to be a challenge for the rest of that unit to pitch flawless baseball.

As such, the Nats failed to win this four-game series, settling instead for a long weekend split. Each loss came by only one run: a 1-0 heartbreaker Thursday afternoon, then today’s high-scoring, back-and-forth affair.

They leave town at 3-7, with a three-game series in Anaheim against the star-studded Angels next before they return to the East Coast.

"We talked about this all week here: You've just got to score as many runs as possible," manager Davey Martinez said. "Anything can happen. Look, we battled. It was just a tough day."

DENVER – Would you believe the Nationals have pitched much better at Coors Field than they did at Nationals Park? That’s certainly been the case for their starters, who have allowed a grand total of five runs in 17 1/3 innings through the first three games of this series, good for a 2.60 ERA. The only reason they’re 2-1 instead of 3-0 is a complete lack of offense in Thursday’s opener.

Can they expect Chad Kuhl to keep the trend going today in the finale? That may be a tough ask. Kuhl had a rough time in his season debut Tuesday against the Rays, giving up four runs in five innings (though all of the damage came in the first and second, and he didn’t allow a hit after that). This is a homecoming for Kuhl, who pitched for the Rockies last season. His numbers at Coors Field: 5.04 ERA, 1.399 WHIP in 12 starts. (Though it must be noted he also shut out the Dodgers here, so it’s not like he hasn’t had some success in the thin air.)

A Nationals lineup that has exploded for 17 runs the last two nights goes up against an unfamiliar foe today in Ryan Feltner. The 26-year-old right-hander owns a career 4-11 record, 6.31 ERA and 1.477 WHIP in 23 games with the Rockies over the last three years.

The Nationals out-hit the Rays all night long, entering the top of the ninth tonight with more than three times as many base hits as their opponents. So why was there a sense of unease as Kyle Finnegan took the mound trying to close out a victory?

Because the Nats didn't make the most of their hits. Yes, they totaled 16 of them, but 13 were singles and the other three were doubles.

The Rays, on the other hand, most definitely made the most of their hits in this game. That's because seven of their 10 went for extra bases, four of those clearing the fence.

And when Luke Raley, Josh Lowe and Yandy Díaz all took Finnegan deep in a disastrous ninth, what should have been an uplifting Nationals victory instead flipped to their most agonizing loss of the young season, a 10-6 defeat that left the home team and a crowd of 15,272 stunned.

"We did what we needed to do to win, and I came up short tonight," Finnegan said. "That's what hurts the most. You want to win the game. I've got to be better."

The Nationals have scored nine runs in four games so far this season, which obviously is not good. In their defense, they’ve faced some pretty tough pitching, from the Braves’ Max Fried and Spencer Strider to the Rays’ Drew Rasmussen. The one opposing starter they had some success against was Atlanta rookie left-hander Jared Shuster. There’s a chance for success tonight against Tampa Bay lefty Josh Fleming.

Fleming, 26, owns a 4.93 ERA and 1.410 WHIP over 171 2/3 career major league innings, and he really struggled last year (6.43 ERA, 1.886 WHIP in only 35 innings) while shuttling back and forth between St. Petersburg and Durham. Knowing the way Kevin Cash manages his bullpen, don’t be surprised if the leash on Fleming is short. If you’re the Nats, look to be aggressive early as they were against Shuster on Sunday and try to take an early lead.

If they can do that, they’ll provide some breathing room for Chad Kuhl, who makes his season debut tonight as the No. 5 starter in place of the injured Cade Cavalli. Kuhl actually becomes the third straight starter to make his Nationals debut, following MacKenzie Gore and Trevor Williams. It’s only the second time that’s ever happened in club history, and to be honest, the first time shouldn’t really count because it was the first four games in club history, with Liván Hernández, Zach Day, Esteban Loaiza and Tomo Ohka taking the ball from Frank Robinson in April 2005. Thing is, all of those guys except for Loaiza had been part of the 2004 Expos’ roster, so it’s not really like they were all joining a new team.

WEST PALM BEACH, Fla. – Chad Kuhl handed the ball to Davey Martinez with one out in the sixth tonight at The Ballpark of the Palm Beaches. The right-hander had just surrendered a leadoff homer and then recorded a flyball out to end his outing at 92 pitches, a solid-if-unspectacular outing against a good Cardinals lineup in the final week of spring training.

Kuhl walked back to the Nationals dugout and began thinking about his next start. The question now: Where and when will that start be?

“We’ve got to figure out what we’re going to do here, but he’s done a great job,” Martinez said. “We’re getting close to the season, and we’ve got to make some decisions. But so far, I like what I’ve seen out of him.”

Thrust into the Nats’ rotation plans after Cade Cavalli tore his elbow ligament last week and required Tommy John surgery, Kuhl seems to have done enough to have locked up the No. 5 starter’s job as the season begins.

The Nationals, though, aren’t ready to make any pronouncements about that. There’s still another 11 or 12 days to go until they’ll need a fifth starter, so that leaves them with some flexibility as they wind up camp.

WEST PALM BEACH, Fla. – It’s going to be a beautiful evening for baseball. If you can’t be down here with us, might as well live vicariously through your TV and watch Bob Carpenter and Kevin Frandsen on MASN.

The Nationals host the Cardinals in Game 25 of 27 on their Grapefruit League slate. They’ve actually done well, record-wise, so far, entering tonight 12-10-2 for the spring (if that matters at all). Most importantly, they’ve been getting excellent starting pitching this week. The quartet of Patrick Corbin (officially named Opening Day starter this afternoon), Josiah Gray, MacKenzie Gore and Trevor Williams combined to post an 0.75 ERA with three walks and 22 strikeouts over 24 innings the last four days.

Chad Kuhl will look to continue those good vibes going tonight against St. Louis. Kuhl hasn’t officially been named the No. 5 starter yet, but it’s hard to imagine anyone else taking the spot from him at this point, especially if he gets through tonight’s outing in one piece. There is, as noted yesterday, a possibility Kuhl doesn’t actually make the Opening Day roster and stays down here to make one final tune-up start in a minor league game before heading north in time to start either April 4 or 5 against the Rays.

Almost all of the regulars are in Davey Martinez’s lineup again tonight, aside from CJ Abrams and Victor Robles. Luis García gets another opportunity to lead off. Joey Meneses gets a start at first base after playing left field the last two nights.

WEST PALM BEACH, Fla. – Three players vying for the final spot on the Nationals’ Opening Day bench remain in big league camp, but one of them is not currently playing.

Jeter Downs, who has twice been hit by a pitch on the hand in the last week, didn’t play Wednesday afternoon against the Yankees and isn’t on the lineup card for tonight’s game against the Astros.

Manager Davey Martinez said X-rays on Downs’ hand were negative, but he does have a contusion and needs at least a few days to heal. That complicates the infielder’s chances of heading north with the club, given how few opportunities remain to make a case.

“I want to see him get some at-bats,” Martinez said. “We’ve been working on some stuff with him hitting, and I want to see him back out there to see if he can do these things we’re asking him to do. But I don’t want to him push himself to try to get back out there. I want to make sure that (he’s healthy).”

Downs, the former top prospect of the Dodgers and Red Sox whom the Nationals claimed off waivers this winter, is batting just .176 (6-for-34) with three RBIs, three walks and 12 strikeouts this spring. His ability to play multiple infield positions as well as the outfield, though, makes him intriguing as a 26th man on the roster.

WEST PALM BEACH, Fla. – It would’ve been easy for Chad Kuhl to take the mound this afternoon at The Ballpark of the Palm Beaches, knowing what has changed in the last week, and feel like he needed to do something more than usual.

With Cade Cavalli now headed for season-ending Tommy John surgery, the Nationals have designated Kuhl as the top candidate to take the final spot in their Opening Day rotation.

What could’ve been considered by some a make-or-break start against the Tigers was viewed by Kuhl as simply the next step in his preparation for the season, no matter where he will be pitching two weeks from now.

“To be honest, I never really put too much stock in spring games or outings,” he said. “We had talked, and for me it’s just trying to do what I can do to focus on getting better, focusing on the things I can control. I talked with (general manager Mike) Rizzo in the offseason about the opportunity and felt like I was on a good path, no matter what happened box-score-wise. I was able to focus on myself.”

Whether the results of today’s start would’ve made a difference or not, Kuhl made sure not to do anything that might jeopardize his chances of making the club. He tossed five innings of one-run ball during the Nats’ 2-1 win, allowing back-to-back hits in the top of the first but then settling into a groove and finishing with six consecutive outs.

WEST PALM BEACH, Fla. – It’s been a warm, dry spring for the better part of a month now, but we did get one rainout last week, and now the weather pattern seems to have changed. It’s supposed to be cooler, windier and cloudier the next several days, with some possibility of rain (more so Monday than today).

The Nationals would much rather play today than not, because they need to get Chad Kuhl stretched out in time for the start of the season, now that the right-hander is likely to be the No. 5 starter. Kuhl made one other start this spring – coincidentally, it came against the Tigers in Lakeland – so he’s probably got two more opportunities to pitch before it counts.

The Nationals have eight of their nine expected regulars in the lineup today, all but Joey Meneses (who of course is still competing for Mexico in the World Baseball Classic). CJ Abrams returns after missing four days with a tight back. Davey Martinez said they’ll watch him closely, but he needs to get into regular-season mode, so they won’t ease him back in too much.

WEST PALM BEACH, Fla. – Though he’s out of the Nationals lineup for the fourth straight day with a tight back, CJ Abrams appears close to returning to game action, probably as soon as Sunday.

Abrams hasn’t played since Tuesday against the Mets, after which he reported tightness in his back. The 22-year-old shortstop suggested it wasn’t anything serious and that he’d be playing if this happened during the regular season.

This morning provided some confirmation of that: Abrams was a full participant in pregame drills with the rest of the starting infielders and fielded grounders, turned double plays and took batting practice with no apparent issues.

What would be the sign that Abrams was good to return to Grapefruit League games?

“Just the whole baseball activity, being on his feet,” manager Davey Martinez said this morning, before workouts. “He’s going to take swings, he’s going to hit, he’s going to do everything. And if everything goes well, hopefully he’ll play tomorrow.”

WEST PALM BEACH, Fla. – The loss of Cade Cavalli to Tommy John surgery is a crushing blow to the 24-year-old right-hander and to the Nationals, who were hoping their top pitching prospect would enjoy a healthy run of success in his first big league season.

Cavalli may still enjoy a long run of success in 2024 and beyond. But in the meantime, the Nats have to figure out who’s going to cover the starts and innings that suddenly opened up with this injury diagnosis.

Manager Davey Martinez said Wednesday he didn’t expect to look outside the organization for help, believing enough fallback options are already in place to fill the void. General manager Mike Rizzo echoed that sentiment Thursday but left the door ajar enough to consider the possibility of outside help.

“We like the depth we have here, but we’re not against looking outside the organization,” Rizzo said. “If something makes sense to us, of course, we’ll certainly look outside and inside.”

The Nationals actually did go outside this winter and added some veteran pitching depth, signing right-handers Chad Kuhl and Wily Peralta to minor league contracts. Both have extensive big league starting experience and seem to have been brought in exactly for this kind of scenario.

JUPITER, Fla. – Though they won’t know results of the MRI on Cade Cavalli’s elbow until later today or Thursday, the Nationals are already making plans to proceed without the rookie right-hander, with a veteran starter in line to take his place for the time being.

“Chad Kuhl, right now, is going to get an opportunity to probably start if Cade can’t do it,” manager Davey Martinez said this morning, before the Nats' game against the Marlins was canceled due to rain.

Kuhl, a 30-year-old right-hander in camp on a minor league deal, has made one Grapefruit League start this spring, tossing 2 1/3 scoreless innings March 5 against the Tigers. He’s also made three relief appearances, including a three-inning stint Monday against the Astros.

A veteran of six big league seasons, the first five of which came with the Pirates, Kuhl owns a career 31-41 record, 4.74 ERA and 1.451 WHIP. He missed the entire 2019 season recovering from Tommy John surgery but returned healthy in 2020. The Delaware native joined the Rockies last year and made 27 starts, going 6-11 with a 5.72 ERA that was more than a run higher than his career mark to that point.

The final numbers don’t tell the full story of Kuhl’s 2022 season. Through his first 10 starts, he was 4-2 with a 3.17 ERA. Then over his final 17 starts – with a brief stint on the injured list due to a strained hip flexor – he was 2-9 with a 7.37 ERA, inflating his season totals.

The Nationals have added another experienced starter to a rotation depth chart that was lacking in that department, signing right-hander Chad Kuhl to a minor league contract with an invitation to big league camp later this month.

Kuhl, 30, has made 111 major league starts, the first 84 of which came for the Pirates from 2016-21. He spent last season with the Rockies, struggling to a 6-11 record and 5.72 ERA in 27 starts, though he did toss a three-hit shutout over the Dodgers on June 27 at Coors Field.

Kuhl actually totaled eight quality starts for Colorado, only one fewer than Patrick Corbin and Josiah Gray produced for the Nationals.

Somewhat surprisingly, though, the right-hander fared worse on the road than he did at home, going 3-7 with a 6.32 ERA and 1.693 WHIP away from Coors Field while going 3-4 with a 5.04 ERA and 1.399 WHIP at mile-high altitude.

During his five seasons in Pittsburgh, Kuhl went 25-30 with a 4.44 ERA. His best performance came in 2017, when he went 8-11 with a 4.35 ERA and 142 strikeouts in 31 starts.
