Mets’ Martinez injures hamstring

MIAMI -- Pedro Martinez slowly walked off the mound. The New York Mets have no idea how long before he’ll return.

Robert Andino’s first career home run with two outs in the 10th inning gave the Florida Marlins a 5-4 victory over the Mets on Tuesday night after Martinez departed with a leg injury.

Already coming off two injury-plagued seasons, Martinez limped away with a strained left hamstring in the fourth inning, after 57 pitches.

“He said he felt kind of a pop,” Mets Manager Willie Randolph said.

Martinez, who was not available for comment, will fly back to New York today for an MRI exam.

Andino had only six extra-base hits and three runs batted in in his first 81 major league at-bats, but hit the game-winner 371 feet to left field off Matt Wise (0-1), the sixth Mets pitcher.

Martinez got Matt Treanor on a groundout in the fourth, but was clearly in discomfort after the pitch, grabbing his midsection and lower back region.

Randolph and medical officials rushed to the mound, talked momentarily with Martinez, then shuffled with him back to the dugout. “We weren’t going to mess around,” Randolph said.
