Chan Ho Park's sore right hamstring is not a serious injury, but the Yankees are taking no chances. They put Park on the disabled list Friday night and recalled lefthander Boone Logan from Triple-A Scranton/Wilkes-Barre.

Park felt some tightness just above the inside of his right knee while warming up Thursday. He had an MRI exam that showed no damage, but Joe Girardi said he would "rather have a guy miss 10, 12 days than six, eight weeks."

Park, 37, missed the final two weeks of the 2009 regular season with the Phillies because of a more severe hamstring injury. He said the current problem is in a different spot on his right leg and is much less painful. "Last year, I couldn't even walk," he said. "I never had pain like that."

Park is 1-1 with a 4.76 ERA in three appearances this season.

Logan, 25, nearly made the Yankees' roster with a strong spring training. He allowed one run in 62/3 innings in three appearances for Scranton, with one walk and nine strikeouts.

Adding another lefthander to the bullpen gives Girardi some new options, but losing Park for a stretch - he's eligible to return April 28 - means that Alfredo Aceves is the only long reliever in the pen.

"I don't know if we'd go two, three innings with him now," Girardi said of Aceves.

Of Logan, Girardi said the key in spring training was fixing his mechanics - getting Logan's leg kick more north-south so he would stay over the pitching rubber instead of flying off to the side. "He took to it very well," Girardi said.

Cervelli in, Posada rests

After catching three straight games and with a day game Saturday, Jorge Posada took a seat Friday night. It was just coincidence, not playing favorites by Girardi, that he had Francisco Cervelli catching CC Sabathia. Cervelli caught Sabathia's near no-hitter against the Rays last Saturday.
