Bastardo, 23, may have thrown his last pitch for a while. The lefthander's velocity was consistently in the mid- to high-80s before he left the game, down from the low- to mid-90s of recent starts. Although the Phillies do not need a fifth starter until July 4, triple-A pitchers Andrew Carpenter and Carlos Carrasco are strong candidates to replace Bastardo, and the Phillies continue to explore trade possibilities.
Bastardo said through interpreter Raul Ibanez that he has felt recent stiffness in the shoulder, but the problem worsened during last night's game. "It's a tightness that I feel, that I can't throw the way I want to," he said. "I felt it [before], but not as much as I did today."
The pitcher said he would consult with the team medical staff today. No further details about the injury were immediately available.
