Minor will undergo shoulder surgery this week, Mark Bowman of MLB.com reports. Renewed shoulder discomfort accompanied Minor's return to elevated ground last month, resulting in his transfer to the 60-day DL. As it turns out, he will need the shoulder operated on, and though nothing's definite, the lefty may very well miss the entire 2015 season as a result. Minor first began experiencing shoulder issues during 2014 spring training.
