Apparently he liked what he saw out of Hughes and AJ in Boston and is going to stick with a six-man staff for at least one more time through the rotation. Girardi also said that he spoke to the players today and that helped postpone his decision.
Here are a couple quotes from Girardi via Jon Lane:
“We liked what we saw from our guys in Boston,” Girardi said. “We thought Hughes threw the ball better than the numbers indicated. We liked what A.J. did and I want to see him build on that, another time through with the different mechanics and see what happens. There’s no rush to make this decision.”

“I’m real curious. I love what I saw from A.J. in Boston,” Girardi said. “What makes it more incredible to me is here’s a guy fighting for his spot. There was discussion about how he might come out of the rotation and he had a tough August. [He decided] you know what? I’m going to try new mechanics for the first time against the Red Sox. That takes a lot of guts.”
