Joe Girardi said on Thursday that the Yankees would consider using a six-man rotation if and when Bartolo Colon and Phil Hughes returned to the Bronx.
Colon has been out since June 11 with a hamstring injury and Hughes has been on the disabled list since mid-April with shoulder inflammation.
Colon is expected to return on Saturday afternoon against the Mets; Hughes' return appears to be imminent as well.
Girardi said that the Yankees would consider expanding their rotation to six starters to make room for both Hughes and Colon.
Colon has pitched extremely well as a starter since taking over for Hughes, though he did start the season in the bullpen.
Hughes struggled in his three starts with the Yankees earlier this season but is an unlikely candidate for the bullpen.
If the Yankees decide to stick with a five-man rotation, they could bump Ivan Nova (7-4, 4.26 ERA) to make room for Hughes and Colon.
Nova said the extra day off rest wouldn't affect him but he'd prefer to pitch on regular rest.
As for CC Sabathia, he didn't seem too enthusiastic about the idea. The big lefty refused to answer a question about a possible six-man rotation. He traditionally prefers to pitch on normal rest.
"Those are things we have to decide," Girardi said. "You do have five guys throwing the ball pretty well, so it's a tough decision on how we do it."
