Pedro Martinez left his start for the Mets against the Marlins on Tuesday night after 57 pitches, according to the Associated Press.

The team claims that he suffered from a torn hamstring.

Martinez retired Matt Treanor on a groundout in the fourth inning and immediately began grabbing his back and midsection.

He allowed four earned runs in a little more than four innings of work.
