March 4, 2026
The Nationals reassigned Ogasawara to minor-league camp Wednesday.
Analysis
Ogasawara will earn $2 million in 2026 after signing a two-year deal with the Nationals in January 2025, but the left-hander no longer possesses a spot on the 40-man roster after Washington outrighted him earlier in the offseason. After coming over from Japan last winter, Ogasawara posted a 6.98 ERA, 1.55 WHIP and 30:17 K:BB over 38.2 innings across 23 appearances (two starts) with Washington.

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.

Analysis
Ogasawara, who turns 28 Tuesday, has pitched for the Dragons for nine seasons, most recently collecting a 3.12 ERA but just 82 strikeouts over 144.1 innings during the 2024 campaign.
