Yankees manager Joe Girardi declined to say if Vazquez will make his next start, saying only that the rotation has been set through New York's upcoming series with the Rays, and that Vazquez will remain in the 'pen at least for Monday's game.
Vazquez has been shuffled between the rotation and the bullpen this season, making three relief appearances. After going five-plus innings in a no-decision Friday at Texas, Vazquez is 10-9 with a 5.06 ERA overall.
"The way I look at it, if I was pitching great, that wouldn't be an issue," Vazquez said. "Obviously, I'm to blame for not throwing the ball well. I know I can help them in the 'pen, too, so whatever they want to do, I'll do."
Girardi said that he could use Vazquez for about an inning on Sunday if needed. The Yankees' bullpen is short for the Rangers finale, with Mariano Rivera, Kerry Wood, Dave Robertson and Chad Gaudin among those thought to be unavailable.
"There's just things we'll have to decide and see how the next few games go," Girardi said.
