The Nationals made a surprise addition to their already crowded rotation mix yesterday when they signed southpaw Shinnosuke Ogasawara to a two-year deal. President of baseball operations Mike Rizzo spoke to reporters (including Mark Zuckerman of MASN and Spencer Nausbaum of the Washington Post) today about the club’s rotation plans for 2025 and where Ogasawara fits into that picture.
Ogasawara, 27, has posted a 3.28 ERA in 596 innings of work over the past four seasons with Nippon Professional Baseball’s Chunichi Dragons. While that’s a solid performance, the lefty’s lackluster 13.6% strikeout rate last year raised plenty of eyebrows when he was posted by the Dragons last month. That skepticism about his ability to make such a profile with such few strikeouts work in the majors led Ogasawara to sign a modest deal that guarantees him just $3.5MM, well below the going rate for even back-end starters in free agency. Rizzo expressed confidence in Ogasawara as a starting-caliber option despite those concerns, but stopped short of fully guaranteeing him a rotation spot or even an active roster spot to open the season in his discussion of the club’s rotation plans.
“We signed [Ogasawara] to be a starting pitcher for us in the big leagues,” Rizzo told reporters, including Zuckerman. “Of course, he’ll have to earn that spot in the rotation. I think there’s going to be great competition for the five spots in the rotation by some good, young, talented players. If he’s not ready for the big leagues, then we could always option him to Triple-A and bring him up sometime during the season. But we anticipate him battling out for a rotation spot, and I think it’s going to be a fun competition to watch.”
That most tracks with Andrew Golden of the Washington Post’s reporting on the state of the club’s rotation. Golden characterizes right-hander Michael Soroka, left-hander MacKenzie Gore, and right-hander Jake Irvin as the three players locked into Opening Day rotation spots if healthy. That leaves two spots in the rotation for Ogasawara, veteran right-hander Trevor Williams, and young southpaws Mitchell Parker and DJ Herz to compete for, though it’s worth noting that Williams himself indicated earlier this month that he’ll be part of the club’s Opening Day rotation. That would leave just one spot for Ogasawara, Parker, and Herz to compete for. Ogasawara seems likely to be the favorite for that role headed into Spring Training, though all three have options remaining and Golden suggested that he or even Williams could be pushed to a bullpen role if Parker and/or Herz look particularly good coming out of camp.
The club’s approach of adding plenty of depth to the rotation to ease their reliance on up-and-coming youngsters without blocking them meshes will with the club’s overall philosophy for this winter. As Nausbaum notes, Rizzo told reporters that given “where [the club is] at right now,” the club was cautious about signing free agents with a qualifying offer attached due to the associated loss of draft capital and international bonus pool money. The club’s reluctance to target qualified free agents led the club to bring in a number of short-term reinforcements this winter.
That includes not only their trio of rotation additions but also Nathaniel Lowe, Josh Bell, Amed Rosario, and Jorge Lopez. All of those veterans come with either one or two seasons of control, preventing them from blocking the young players and prospects that the Nationals have been building around since they first began what has become a lengthy rebuild back in 2021. The club’s fortunes appear to be on the upswing headed into 2025 with that group of intriguing youngsters in the rotation and an outfield that currently projects to feature full seasons from James Wood and Dylan Crews in the corners. Cade Cavalli, Robert Hassell III, and Brady House are among the other noteworthy prospects in the club’s pipeline who have yet to establish themselves in the majors but could arrive at some point this season.
That reluctance to block top prospects and young players seems to have played a significant role in how the club’s offseason has played out to this point. Early in the winter, the Nationals were among the teams most frequently connected to Christian Walker before he ultimately signed with the Astros. Walker, of course, received a Qualifying Offer from the Diamondbacks that may have limited the Nationals’ interest in him and led to them pivoting towards the additions of Lowe and Bell. It’s also possible that the club’s desire to avoid blocking young players contributing to them not signing second baseman Gleyber Torres. Torres made clear shortly after he signed with the Tigers that the Nats were among the teams pursuing him but that they had wanted him to move to third base in order to accommodate 24-year-old Luis Garcia Jr. after he enjoyed something of a breakout season in 2024. When Torres landed elsewhere, the Nationals opted to sign Rosario, who has moved around to a number of positions all throughout his career and should have no trouble playing out of position if needed.
