Dodgers Moving Ben Casparius To Starting Rotation

After a dominant start to the season as a reliever, right-hander Ben Casparius is set to get an opportunity to prove himself as a starter with the Dodgers. Initially tabbed as an opener for a bullpen game against the Padres today, manager Dave Roberts revealed to reporters (including Fabian Ardaya of The Athletic) before today’s game that Casparius could be stretched out further to operate as a starting pitcher while the club is short-staffed due to the recent loss of Tony Gonsolin. After today’s outing, where he threw four innings of one-run ball, Roberts announced that Casparius’s next outing would be as a starter, as relayed by MLB.com’s Sonja Chen.

It’s hard to argue Casparius hasn’t earned a look in a larger role, as he’s done nothing but produce in the majors for the Los Angeles. The club’s fifth-rounder back in 2021, Casparius made his big league debut last August and immediately delivered with a 2.16 ERA and 1.73 FIP across 8 1/3 innings of work down the stretch. After debuting just in time to be eligible for the postseason, Casparius was a part of the Dodgers’ playoff roster mix during last October’s World Series run and continued to deliver on the biggest stage with a 1.42 ERA in 6 1/3 postseason innings against the Mets and Yankees.

This year, it’s been more of the same over a much larger sample size. His 44 innings of work this season have seen him produce a 2.86 ERA with a 1.89 FIP while striking out 26.0% of his opponents and walking just 5.1%. Those numbers are nothing short of brilliant, and while Casparius hasn’t ever been challenged with facing the opposing lineup a third time in his career he maxed out at 70 pitches earlier this year and threw 54 in today’s outing, suggesting he’s not too far from being fully stretched out to start. Even if the Dodgers don’t want to use him much deeper in games than the fifth inning, it’s easy to see the logic in giving Casparius this opportunity given the other options the club has at its disposal at the moment.

With key arms like Blake Snell, Tyler Glasnow, Roki Sasaki, and Gonsolin among the eight starting pitchers presently on the injured list and Shohei Ohtani still at least a few weeks out from pitching in big league games, the Dodgers need to turn to their depth options to fill out the rotation behind Dustin May, Clayton Kershaw, and Yoshinobu Yamamoto. Justin Wrobleski had previously gotten the opportunity to be the fourth starter behind that trio, but the lefty has a 7.20 ERA in 15 innings of work at the big league level this year. Bobby Miller (12.60 ERA) and Landon Knack (5.12 ERA) have also struggled in their own limited opportunities at the MLB level, and the only other starter on the 40-man roster at present is right-hander Nick Frasso. Frasso not only hasn’t yet made his MLB debut, but he’s struggling badly with a 5.31 ERA in 42 1/3 innings of work at Triple-A this year.

With so few quality starting options presently at the club’s disposal, giving Casparius a chance to build on today’s strong (albeit brief) start against San Diego is practically a no-brainer. Even so, it’s difficult to imagine Casparius pitching himself into a completely permanent role in Los Angeles’s rotation; with so many talented arms in the organization ahead of him on the depth chart, he’ll likely need additional injuries to crop up if he hopes to remain in a rotation role even after ace-level pitchers like Snell and Glasnow return from the injured list.
