The San Francisco Giants placed right-hander Matt Cain on the 15-day disabled list Monday.

Cain, who was scheduled to start Monday night at the Pittsburgh Pirates, was replaced by righty Yusmeiro Petit.

Cain missed his last start after cutting the tip of his right index finger with a knife while making a sandwich before the game. He was initially expected to miss just the one start, but the team decided to place him on the DL on Monday.

The move it backdated to April 25, meaning he could come off and face the Dodgers in Los Angeles this weekend.

The club recalled right-handed reliever Jake Dunning from Triple-A Fresno to fill Cain's spot on the active roster.

Petit replaced Cain last Tuesday and threw six scoreless innings in the Giants' 6-0 victory over the San Diego Padres.

In the following days, all indications were that Cain would rejoin the rotation on schedule and start the opener of the Pirates series as the streaking Giants, winners of nine of their last 10 games, continue a three-city road trip after a sweep in Atlanta.

On Sunday, Cain was officially was named to start and Cain said that he would be able to pitch without restrictions, a statement that was affirmed by Giants manager Bruce Bochy.

Cain, who has made just one other trip to the disabled list in his career, is 0-3 with a 4.35 ERA in five starts this season and that is reminiscent of 2013, when he went 0-2 with a 6.39 ERA during April.

Cain, however, was 4-0 last May before leveling off to go 8-10 with a 4.00 ERA.
