Mike Bolsinger

Righthander Mike Bolsinger has served as a swingman this spring, and his pro future is as a reliever, his role on Arkansas' 2009 College World Series team. Coming out of the bullpen, he has an 89-92 mph sinker and a slider. The 6-foot-2, 212-pounder throws strikes, competes well and could make a useful middle reliever in the big leagues. The Athletics drafted him in the 33rd round as a junior last year.
