As Matthew mentioned last night, Shaun Marcum left Friday’s start against the Red Sox after laboring through 45 pitches in the first inning.
While Marcum appeared to be favoring his leg during the abbreviated outing, Tom Haudricourt of the Milwaukee Journal-Sentinel reports that he was diagnosed with a strained left hip flexor.
“I didn’t want to come out after the first inning,” he said. “But we wanted to be smart about it, not do anything stupid that might make me miss more time.”
Marcum is scheduled to be reevaluated today and is at risk of missing his next scheduled start. Marco Estrada, who threw four innings in relief last night, would be the most likely replacement if he needs to miss any time.
Marcum, who was acquired from the Blue Jays for Brett Lawrie during the winter, is 7-2 with a 2.85 ERA and 84/24 K/BB ratio over his first 15 starts this season.
