Boston Red Sox closer Andrew Bailey was throwing pregame on Sunday from 150 feet to test his arm out (via ESPN Boston). Bailey has missed the entire 2012 season so far after having thumb surgery in Spring Training.

Red Sox manager Bobby Valentine said that he watched most of Bailey's throws and that his pitcher looked good. "I saw all but the last five throws of it, and he looked pretty good. Tomorrow is going to be a good test for him, to see how he feels. He was stretching it out pretty good.''

When Bailey returns, is there a possibility that he won't be the closer after all? When Boston traded for Bailey in the offseason, they anticipated him being their closer. Since the injury, Alfredo Aceves has assumed the closer role and has made 18 saves (5th in the AL) in 21 opportunities. Bailey is 7-10 in his MLB career with a 2.07 ERA and 75 saves in 84 opportunities.
