TORONTO -- Philadelphia left-hander Antonio Bastardo will miss his next start because of a strained shoulder, the team said Sunday.
Bastardo left injured in the fourth inning of his last start and returned to Philadelphia this weekend, where he is scheduled to see a doctor on Monday.
Pitching against Tampa Bay last Thursday, the rookie gave up six runs in the first two innings to waste a 4-0 lead. He was replaced by Chad Durbin after a one out walk in the fourth.
Bastardo is 2-3 with a 6.75 ERA in five starts and has lost his past three outings.
The Phillies are off Monday and begin a three-game series in Atlanta on Tuesday. Right-hander Joe Blanton will start the opener, with left-hander Cole Hamels pitching on regular rest in Bastardo's spot Wednesday. No starter has been announced for Thursday's finale.
