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.

Awarded another start
Ogasawara is slated to start Saturday's game against the Brewers in Milwaukee.
Analysis
With Trevor Williams (elbow) hitting the injured list last week with a season-ending UCL tear, Ogasawara was summoned from Triple-A Rochester to fill the opening in the rotation. The 27-year-old proceeded to get thrashed in his MLB debut last Sunday, surrendering four earned runs on seven hits and no walks over 2.2 innings in a loss to the Red Sox. With prospect Cade Cavalli (14 earned runs allowed over his last two starts) struggling at Triple-A, the Nationals don't have many appealing alternatives for their fifth starter spot, so Ogasawara will receive at least one more turn as he looks to build a case for sticking around with the big club coming out of the All-Star break.
