In the sixth inning on Tuesday night, Yankees reliever Jose Veras hit Boston's Jason Bay with a pitch.
"Penny's control was pretty good, and I thought it was on purpose," Girardi said Friday. "You know, that's all part of baseball, I guess. You know, we hit Bay, and I know Jose did not hit him on purpose. I mean, Jose has struggled with his control. But things like that happen. You know, you expect something could happen in return."
Rodriguez declined comment before the Yankees played the Mets on Friday night.
Boston manager Terry Francona didn't want to address Girardi's accusation.
"I thought Brad Penny pitched very well. That's my comment," Francona said before the Red Sox played the Phillies.
