2025 Fantasy Outlook
Ogasawara was posted in December and will look to make the jump to MLB ahead of his age-27 season. The fact that the lefty still has several years of his prime ahead of him will be appealing to potential suitors, but it's not clear that Ogasawara has enough in his profile to merit much interest. His 3.12 ERA last season was above league-average for NPB (2.96), while his 13.6 K% was well below average (18.8%) - not the sort of performance which says a player is ready to jump to a new level. For his career, Ogasawara's 3.67 ERA is higher even than the likes of Shun Yamaguchi (3.36) and Kohei Arihara (3.37), two pitchers who failed to make an impact in their brief MLB careers, to say nothing of long-term success stories like Masahiro Tanaka (2.67) and Kenta Maeda (2.39). A 5-foot-11 frame and a fastball that sits a modest 91-93 mph are further points against the lefty, though an elite 3.7 BB% does at least provide one reason for MLB teams to think he's a project worth investing in.

Signed a two-year, $3.5 million contract with the Nationals in January of 2025.
Sent down to minors
The Nationals optioned Ogasawara to Triple-A Rochester following Saturday's 6-5 loss to the Brewers.
Analysis
Making his second start for the Nationals on Saturday, Ogasawara took a no-decision after allowing three earned runs on four hits and one walk while striking out two over four innings. While he performed better Saturday than he had in his MLB debut, the southpaw won't retain his rotation spot after giving up seven runs over 6.2 frames across his first two MLB starts. It's not yet clear who Washington will turn to as its new fifth starter moving forward, but the team has some time to decide with the All-Star break just around the corner.
