Manager Bob Melvin said Friday that he's "optimistic" Irvin (hip) will make his next scheduled start against Detroit on Tuesday, Matt Kawahara of the San Francisco Chronicle reports.
Irvin allowed three runs on seven hits and two walks before exiting Tuesday's loss after three innings due to hip discomfort. Based on Melvin's comments, the lefty is trending toward being able to take the ball Tuesday in Detroit, but how he progresses in coming days will likely be the decisive factor in that decision. Daulton Jefferies is expected to start in his place if he's unable to go.
