Even with two extra spots in September, the Nationals are currently only carrying four true outfielders on their active roster. That’s usually the standard for any team: three starters and one backup on the bench.

But manager Davey Martinez, in fact, has utilized six players in the outfield since the roster shakeup at the trade deadline.

Victor Robles and Lane Thomas have been in Washington all season long. Joey Meneses (typically a first baseman) and Josh Palacios were brought up to fill the holes left by Juan Soto and Josh Bell, with Palacios making a couple of trips back-and-forth between the majors and Triple-A Rochester. Alex Call was selected off waivers from the Guardians on Aug. 7. And utilityman César Hernádez has appeared in left field four times to start September.

This is part of the process for the Nationals to see what they have in these players before the season ends in three weeks.

For the most part, they know what they have in Robles, who you may have noticed has not played since Sept. 7 in St. Louis. He was scratched from the starting lineup with a stiff neck the following day, but has been seen walking around the Nationals clubhouse this week with seemingly no issues.

About an hour north up I-295, a rival organization provides a blueprint for the Nationals and their rebuild.

A few years ago, the Orioles began the process of rebuilding their own organization. Now they are starting to turn the tide into contention, finding themselves unexpectedly four games out of an American League wild card berth.

That path back to contention is a similar one the Nationals want to follow now that they have fully embraced their own rebuild. And perhaps reach that turning point sooner.

This week’s two-game series against the Orioles was a good chance for the Nats to measure their young players against some of the best prospects in baseball.

Adley Rutschman, Gunnar Henderson, Kyle Stowers and DL Hall were all at one time ranked in multiple publications’ top 100 prospects lists. They also headlined an Orioles farm system that has been one of if not the best in the sport since executive vice president and general manager MIke Elias took over in 2018.

With the all-important and definitely real prize of the MASN Cup on the line, the Nationals could neither hold a close lead nor produce a late rally against their rivals from Baltimore.

After splitting two games at Camden Yards in June and dropping the Washington opener here last night, the Nationals fell to the Orioles 6-2 before an announced crowd of 32,497 to lose this year’s edition of the Battle of the Beltways.

Things went off the rails for the home team in the seventh while holding a 2-1 lead.

Mason Thompson, whose 0.60 ERA to begin the night was impressive even though it didn’t come in many high-leverage situations, entered in relief of starter Patrick Corbin for the start of the frame.

After back-to-back singles to Jesús Aguilar (with Terrin Vavra pinch-running) and pinch-hitter Cedric Mullins, Thompson faced Gunnar Henderson, one of baseball's top prospects.

The Nationals received good news on two of their top pitching prospects this afternoon that involved both of them throwing a baseball in different ways.

After having been shut down for two weeks with right shoulder inflammation, Cade Cavalli was cleared to pick up a ball and resume throwing by team doctors and the medical staff.

His follow-up exam yesterday revealed that he was healthy enough to play a game of catch today at Nationals Park.

“Very good. He's actually playing catch as we speak,” manager Davey Martinez said of Cavalli’s follow-up exam and resumption of throwing. “It went really well. Inflammation’s gone. He said he feels great. Doctor evaluated him. Our medical staff put him through the gamut yesterday and today, so he's out there playing catch. So we'll see how he feels. This is great news for us. But with that being said, we still got quite a bit of ways (to go). But it's nice to see him out there throwing again.”

Cavalli was shut down after reporting unusual soreness in his right shoulder after his Aug. 26 major league debut. It was alarming news for the Nats after their top pitching prospect had finally earned the opportunity to debut in the bigs. At the time, the belief was that Cavalli would be done for the year out of extreme precaution and with only a month left in the season.

The Battle of the Beltways was split last year, with the Nationals and Orioles sweeping three-game series on their respective home fields. A Nationals win tonight would ensure a season split for the second year in a row.

The two rivals split two games in June at Camden Yards. The Orioles won the first game of this two-game set in D.C. last night. The Nationals hope Patrick Corbin and a resurgent offense can earn the split tonight. 

Corbin was charged with three runs and seven hits with six strikeouts over four innings in a rain-shortened loss to the Orioles on June 22. He also gave up home runs to Austin Hays (who ended up hitting for the cycle in a game that was called after just six innings) and Anthony Santander. In his career, Corbin is 1-4 with a 5.50 ERA in seven appearances (six starts) against Baltimore.

Tyler Wells makes his 22nd start of the season tonight, but just his second since coming off the injured list last week with a left oblique strain. The right-hander completed only two innings on 34 pitches against the Blue Jays in his return. In that June 22 matchup against Corbin, Wells tossed five scoreless innings with four walks and four strikeouts.

While Wells continues to stretch out, old friend Austin Voth is expected to back him up as a long reliever out of the bullpen. The Nats designated Voth for assignment on May 31 and the Orioles selected him off waivers on June 7. In 19 relief appearances with the Nats, Voth had a 10.13 ERA and 2.143 WHIP. In 18 games (14 starts) with the Orioles, Voth has a 2.82 ERA and 1.209 WHIP.

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.

With a victory this afternoon, the Nationals would win the first series against the Athletics played in D.C. since 2005 and the first ever at Nats Park. And they would win this matchup between two teams with two of the worst records in baseball. A matchup that is now meaningless with next year’s MLB Draft lottery. 

After Aníbal Sánchez earned his first win of the season last night, Paolo Espino will look to do the same today. Entering his first career start against the Athletics, Espino is 0-6 with a 4.35 ERA in 34 appearances (14 starts) this year. He made two relief appearances against the A’s in 2017 as a member of the Rangers. 

Espino will be pitching on normal rest after making his last start on Saturday, thanks to Monday’s off-day. Cade Cavalli was supposed to make his second major league start this afternoon, but landed on the 15-day injured list with right shoulder inflammation. Cory Abbott was recalled yesterday to take the top prospect’s spot on the roster and will be available out of the bullpen.

The Athletics will get to see one of their own top prospects make his major league debut in Ken Waldichuk. The 24-year-old lefty is Oakland’s No. 3 prospect, per MLB Pipeline, and was the centerpiece of a four-player package the A’s received from the Yankees in exchange for Frankie Montas and Lou Trivino before the deadline. Waldichuk posted a 2.84 ERA, 1.158 WHIP and 137 strikeouts in 95 innings over his 21 starts between Double-A and Triple-A in the Yankees and A’s systems.

Major league rosters expand to 28 players today. Catcher Tres Barrera and right-hander Mason Thompson have been recalled from Triple-A Rochester.

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.

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.

FREDERICKSBURG, Va. – James Wood grew up about an hour away from Nationals Park in Olney, Md. He attended Nationals games while starting his high school career as a two-sport athlete at St. John’s College High School in D.C. before transferring to IMG Academy in Bradenton, Fla., to focus on baseball.

When the Padres drafted him in the second round of last summer’s MLB Draft, he moved even further away from his hometown. But a little over a year later at this summer’s trade deadline, Wood found himself on his way back to his original neck of the woods as part of the five-prospect package the Padres put together to acquire Juan Soto and Josh Bell from the Nationals.

Wood entered the Nats system and was assigned to low Single-A Fredericksburg, which operates about an hour and half south of D.C. and places him back in a familiar region. And familiar traffic issues.

“It's nice. I'm like, what, I'm gonna say like an hour and 30 minutes (from home),” Wood said outside the FredNats clubhouse in left field at Virginia Credit Union Stadium. “I mean it really just depends on traffic. Like it could be an hour and 20 (minutes) to two hours. But just being able to really go home, if I need something from home, be able to stop by on off-day, just having my family here just about every game, it's real nice. So, I'm glad to be back home, glad to be close to family, close to home, all that stuff.”

Some players need an adjustment period when traded from one organization to another. Rarely do young prospects land near the city in which they grew up.

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.
