Nationals Select Eddie Rosario, Jesse Winker, Matt Barnes

The Nationals announced this morning that they’ve selected the contracts of right-hander Matt Barnes, outfielder Eddie Rosario, and outfielder Jesse Winker. In corresponding moves, right-hander Mason Thompson and left-hander Jose A. Ferrer have been placed on the 60-day injured list. The club’s 40-man roster is now at capacity.

That Barnes made the roster is hardly a surprise. A veteran of ten major league seasons, the 33-year-old is coming off a down season with the Marlins that saw him struggle to a 5.48 despite a decent 4.15 FIP. Prior to his down 2023 campaign, however, Barnes had long been one of the more reliable late-inning relief arms in the game with the Red Sox. Barnes posted a 3.91 ERA with a 3.42 FIP from 2016 to 2022, striking out an excellent 31.3% of batters faced during that time while walking 11.3%. Those seven seasons saw the right-hander pick up 47 saves and 96 holds as a mainstay toward the back of the club’s bullpen. Barnes figures to receive another chance at a late-inning role in D.C. now that he’s made the team, where he’ll compete for high-leverage work with fellow veteran arms Hunter Harvey and Tanner Rainey ahead of closer Kyle Finnegan.

That both Rosario and Winker made the roster is somewhat more surprising. After all, both are defensively limited left-handed hitters who profile best as part of a platoon. That overlap didn’t deter the Nationals from rostering them both, however, and both outfielders certainly have a case to make the roster in isolation. Rosario has typically been a roughly average hitter throughout his career, as exemplified by him .255/.305/.450 with a wRC+ of exactly 100 in 142 games with the Braves last year. Those numbers are more or less in line with his career output of .268/.305/.460 (102 wRC+), though its worth noting that his career numbers are dragged down somewhat by a brutal 2022 season that saw him hit a paltry .212/.259/.328 while he battled vision problems. That issue appears to have been rectified by a laser eye procedure, however, and Rosario seems to be a good bet to produce average numbers as a regular in left field, even as his 23.6% strikeout rate last year is a far cry from the 16.5% figure he posted during his peak seasons with the Twins from 2017 to 2020.

As for Winker, the 30-year-old was among the more productive hitters in the league during his five-year tenure with the Reds, slashing an excellent .288/.385/.504 in 413 games from 2017-21, which included an All Star nod during the 2021 season. Winker was shipped to the Mariners ahead of the 2022 season, however, and took a step back at the plate during his time with the club as he hit a roughly league average .219/.344/.344 during his time with the club. Winker fell even further upon being traded to the Brewers prior to last year, as he struggled to a .199/.320/.247 slash line while battling neck injuries. While Winker doesn’t offer the same reliable production as Rosario, he could be the far more impactful bat if he can regain the form he enjoyed during his time with the Reds.

With young outfielders Alex Call and Jacob Young having been optioned to Triple-A last night and manager Davey Martinez telling reporters (including Spencer Nusbaum of the Washington Post) that Stone Garrett will begin the season on the injured list, however, the club clearly feels comfortable entering the season with an outfield mix that will prominently feature both Rosario and Winker. With Lane Thomas and Victor Robles entrenched as regular options in right and center field, respectively, Winker and Rosario will join first baseman Joey Gallo as left-handed hitters in the club’s lineup with Joey Meneses serving as a right-handed complement to all three. Assuming Gallo will be afforded regular at bats at first base, that would leave at least one of Rosario or Winker to remain in the lineup against left-handed hitters. Given Winker’s abysmal .205/.321/.338 slash line against southpaws, it seems likely that the bulk of starts against lefties will go to Rosario, at least until Garrett returns from the injured list.

That Ferrer and Thompson will start the season on the 60-day IL is hardly a surprise. Thompson is rehabbing Tommy John surgery while Ferrer is dealing with a back strain that Martinez (as relayed by Nusbaum) has indicated will keep him from throwing for another 4-6 weeks.
