PITTSBURGH -- Matt Cain's stay on the disabled list is likely to be a short one. The San Francisco Giants right-hander expects to be activated Saturday for a start against the Dodgers in Los Angeles.

Cain originally was scheduled to pitch Monday night against the Pittsburgh Pirates, but the Giants instead placed him on the 15-day disabled list following Sunday's win over the Braves in Atlanta because of a cut on the tip of index finger of his right hand. The move is retroactive to April 24.

"Just playing it safe," Cain said before the Giants rallied to beat the Pirates 11-10 in 13 innings. "I'll be fine."

The Giants changed their plans with Cain after the cut opened Sunday when he threw for the first time without a protective covering on the finger. However, the team's medical staff is confident Cain will be ready to pitch Saturday.

Cain was injured April 29 about an hour before his scheduled start against the San Diego Padres. Cain made a ham and cheese sandwich in the clubhouse and was trying to cut it into four triangles when he dropped the knife and was cut while trying to catch it.

"The cut is in a tough spot, and the seams of the ball really aggravated it," manager Bruce Bochy said. "It just made sense to have him skip the start. It's better to err on the side of caution."
