Dodgers right-hander Emmet Sheehan hasn’t pitched this season while rehabbing from a forearm injury. He’d recently resumed throwing to live hitters, but manager Dave Roberts told reporters Sunday night that the 24-year-old righty has been shut back down because his arm “hasn’t been responding” the way Dodgers medical personnel hoped

Sheehan said he had another round of testing on his arm that didn’t reveal any structural damage, but Roberts still called his injury a “longer-term situation.” The Dodgers had already transferred him to the 60-day injured list at the end of March.

Sheehan entered the 2023 season as one of the Dodgers’ top pitching prospects and pushed his way into top-100 consideration with a strong minor league showing early last year. 

By mid-June, he was up in the big leagues for his debut. While the right-hander’s 4.92 ERA in a subsequent sample of 60 1/3 innings didn’t exactly cement him as a long-term fixture just yet, he entered camp as perhaps the favorite to land a rotation spot behind Tyler Glasnow, Yoshinobu Yamamoto, Bobby Miller and James Paxton

That spot instead went to fellow righty Gavin Stone, who started his 2024 campaign with two shaky starts before an excellent third outing that saw him carry a perfect game into the sixth inning before running into trouble.

The setback for Sheehan creates further uncertainty in a Dodgers rotation that also has Miller, Walker Buehler, Tony Gonsolin, Clayton Kershaw and Dustin May on the injured list. 

Sheehan’s status on the 60-day IL already meant he was out until at least mid-May, but there’s no way to gauge how long he might be expected to miss right now.

The Dodgers still rank 10th in the majors in rotation ERA, thanks in no small part to a dominant start to the season from Glasnow. Some alarm bells sounded when Yamamoto was torched for five runs in one inning during his MLB debut, but he’s responded by rattling off 15 innings with just three runs allowed while posting a terrific 19-to-3 K/BB ratio. 

Paxton has quality run-prevention numbers, but his success isn’t sustainable if he keeps walking more hitters than he’s striking out. He’s issued 14 free passes in 16 innings, yielding a walk to a glaring 20.6 percent of his opponents on the season. He’s fanned just 10 (14.7 percent).

In Glasnow and Paxton, the Dodgers are banking on a pair of oft-injured veterans to help lead the staff while awaiting the returns of Buehler, Kershaw and May. 

Buehler is expected to make another rehab start this Thursday, per Mike DiGiovanna and Jack Harris of the L.A. Times. His most recent rehab outing was cut short when a comebacker struck his pitching hand, but Buehler escaped that injury scare unscathed. 

Roberts indicated that Buehler is targeting 80 to 85 pitches in that scheduled Thursday outing. He’ll be reevaluated after that point. If the team feels he’s ready, that’d point to a return next week. If he needs one more rehab start following Thursday’s outing, he could still return in the final days of April.
