Winckowski (1-0) allowed one run on four hits, one walk and a hit batsman over three innings Friday, earning a win over the Angels.
Winckowski has been stellar out of the Boston's heavily used bullpen. The 24-year-old right-hander has allowed two runs in 12 innings over six relief appearances. He came through the system as a starter but is expected to remain in a multi-inning relief role for now. Winckowski's a strike-thrower and not afraid to pitch to contact.
