Athletics pitcher Sean Nolin will be held back a few days due to a groin issue, according to the San Francisco Chronicle.
Nolin won't throw a side session for the first few days of camp. The issue seems minor, and Nolin should start throwing soon. The 25-year-old was acquired in a trade from the Blue Jays during the offseason. He could compete for a spot in the team's rotation if he can get healthy.
