Girardi again refused to call Stewart the assigned backstop for Sabathia on Thursday, even as the battery was plugged together for a fifth straight start.
Sabathia entered Thursday having won four straight outings with Stewart, posting a 3.16 ERA and holding opponents to a .190 batting average over the stretch. Sabathia said that he continues to click with Stewart, having shaken off Stewart just once in the last three outings.
"He's caught him three or four starts, but I'm not saying it's going to be that way the whole year," Girardi said. "Everyone is going to want to make something of it right now, but it's not going to be that way the whole year."
Girardi said that he has been choosing to give Russell Martin time off on days when Stewart could catch against a left-handed starter. Girardi said that if the Yankees were in the playoffs, he would have Martin -- and not Stewart -- catching Sabathia.
"Russell is our No. 1 catcher," Girardi said, adding, "I believe Russell is going to do a good job with him as well."
