Mets’ Martinez out least four weeks

Pedro Martinez will be sidelined at least four weeks with what the New York Mets said was a mild strain of his left hamstring.

The three-time Cy Young Award winner was put on the 15-day disabled list before a game against the Florida Marlins on Wednesday night.

Martinez was injured Tuesday night and returned to New York for an examination.

“He’s an unfortunate loss,” pitcher John Maine said. “Everyone knows what Pedro can do.”

Seattle Mariners All-Star closer J.J. Putz was put on the 15-day disabled list because of a rib-cage injury.

Putz, who converted 40 of 42 save opportunities last season, felt discomfort on a pitch against the Texas Rangers on Tuesday, when he blew a save by giving up a go-ahead home run to Josh Hamilton in the top of the ninth.

The Philadelphia Phillies designated infielder Wes Helms for assignment and have 10 days to trade Helms, who is due $2.9 million this season, or put him on waivers.

Tampa Bay Rays pitcher Scott Kazmir threw 44 pitches during a 13-minute bullpen session.

Kazmir has been slowed by a left elbow strain, which he felt while warming up for an intrasquad game Feb. 26. He expects to have another mound session Saturday.
