The Philadelphia Phillies placed Cliff Lee on the 15-day disabled list on Saturday, three days after he strained a muscle in his left side in the 10th inning of his gem at San Francisco.

"We're being very cautious with this," general manager Ruben Amaro Jr. said. "There's no reason for him to kind of completely blow it out because it's an injury that if he hurts himself and really pulls it, we could lose him for a long time. We'll shut him down, get him right and hopefully he'll miss only a couple of starts and go from there."

Lee strained his left oblique.

"I don't know what pitch it was, but he must have made a pitch that bothered him a little bit," Amaro said.

Lee threw 10 scoreless innings Wednesday night at San Francisco but got a no-decision. The Giants won 1-0 in 11 innings.

The lefty had been scheduled to pitch Monday night at Arizona. Right-hander Kyle Kendrick is now scheduled to make that start.

To take Lee's spot on the roster, the Phillies recalled lefty Joe Savery from Triple-A Lehigh Valley.
