NEW YORK -- Hiroki Kuroda wasn't ace-like on Sunday, but he was good enough.
Kuroda allowed just two earned runs in six innings to hold Boston in check in the Yanks' 4-3 win.
The face-saving victory helped the Yankees avoid a sweep and may have helped Kuroda, once the unquestioned ace of the Yankees' staff, get back on track.
"Kuroda did an incredible job," Girardi said.
The veteran battled a high pitch count early on to give the Yanks six strong innings, which is significant given the state of the Yankees' pen.
In the sixth, Kuroda allowed a leadoff double to David Ortiz but limited the damage to just one run by two groundouts and flyout.
"To get through that sixth, with who he had to get through, was really important," Girardi said.
STEWART OK: X-rays on Chris Stewart's foot came back negative and he hopes to play on Monday. But Joe Girardi hinted that the catcher may have to rest for a few days.
Stewart was hit by a pitch leading off the third inning. The pitch caused a contusion on Stewart's left foot. He was sent for precautionary X-rays and replaced by Austin Romine in the sixth inning. Stewart stayed in the game because he works well with Kuroda.
RELIEF FOR THE PEN? Girardi is hopeful that David Robertson and Boone Logan can return to the mound sometime during the upcoming four-game series against Baltimore. Logan received a cortisone shot to relieve inflammation in his left arm.
Robertson (shoulder tendinitis) hasn't started throwing yet. He's been sidelined since Friday night.
