What It Means:

Oh made an early exit on Wednesday after experiencing some renewed discomfort in his groin -- an issue that held him out of for a few games earlier this month -- but he doesn't seem too concerned about it.

Oh has been excellent through his first major league season, posting a 1.85 ERA with a 2.43 SIERA and 33.0 percent strikeout rate through 77 2/3 innings pitched.
