Ivan Nova, Dustin Moseley and Phil Hughes will start against the Blue Jays before an off-day on Thursday. It would then be A.J. Burnett's turn on Friday, but Girardi could also opt to start CC Sabathia on regular rest in the series opener in Chicago.
"Right now, there's nothing etched in stone," Girardi said before Sunday's finale with the Mariners.
Complicating the issue was Sunday's forecast at Yankee Stadium. With rain expected most of the day, Girardi wasn't sure how many innings he'd get out of Sabathia and how much he'd need to dip into his bullpen.
However Girardi decides to set up his rotation, it's unlikely that Burnett and Javier Vazquez will remain back-to-back. Girardi liked having Francisco Cervelli catch each of those pitchers -- something he hasn't been able to do as easily with the two going on consecutive days the last three times through the rotation.
Girardi did say that, as far as he knows, there is nothing physically wrong with Vazquez, who turned in one of his worst efforts of the season on Saturday.
"Physically, we've had no issues with him," Girardi said. "And he has not complained of anything."
