"Right now, we're on rotation," Girardi said. "It's no secret Javy's struggling, and it's something that we've talked about. We've got to find a way to get him going."
Girardi said that Vazquez has looked sharp in his bullpen sessions and his warmup prior to Saturday's start against the White Sox, but the veteran has had difficulty translating those results to the diamond. Vazquez is 1-3 with a 9.78 ERA in five starts this season.
Girardi recalled the time David Cone threw him out of the bullpen because Cone's stuff was so bad before a start; the pitcher proceeded to give up one run in seven innings.
"Sometimes when you get in the heat of the moment, your mechanics can get out of whack," Girardi said. "You can say it's physical, you can say it's psychological, you can say it's mechanical. Whatever it is, we have to fix it."
With an off-day on Thursday, the Yankees can skip Vazquez's turn and throw the rest of their rotation on regular rest. Phil Hughes, CC Sabathia, and A.J. Burnett would pitch in Boston in that scenario. New York could also opt to call a starter up from Triple-A Scranton/Wilkes-Barre or give the ball to longman Sergio Mitre, who tossed three hitless innings in relief on Saturday. Mitre was 3-3 with a 7.16 ERA in nine starts for the Bombers in 2009.
