"It didn't look too bad," Girardi said. "It was a little swollen [on Friday] night, but they'll do a lot of treatment to try to get that swelling out. To me, what's really going to matter is if he can hold the ball and feel comfortable."
Vazquez was injured in the seventh inning of Friday's 2-1 Yankees victory over the Mets while trying to get a bunt down. He is expected to throw a bullpen session on Monday during the Yankees' off-day to prepare for that start against Minnesota.
Vazquez said that he was "embarrassed" by the injury. It could have happened to anyone, but Vazquez considers himself an experienced hitter -- last year, he had 91 plate appearances with the Braves and led the Majors with 20 sacrifice bunts.
Girardi said that Vazquez's malady was just one more item to consider on the topic of pitchers batting in Interleague Play against National League clubs. Of course, the Yankees still vividly recall losing Chien-Ming Wang to injury in 2008, and they're thankful Vazquez's injury does not appear to be as serious.
"It's always somewhat of a concern, because it's not something that they do every day," Girardi said. "Their bodies aren't accustomed to it necessarily. If you're in the National League, you probably hit most every day, but it's still different when you hit in the game because the intensity turns up."
