The team said Martinez felt something during pregame warm-ups, but apparently it wasn't serious enough for him to pull out of the lineup. Instead he allowed six runs in his one inning against the Phillies, who rolled to a 13-0 win.
The Mets list him as day-to-day.
Martinez, who went on the disabled list with a sore right hip after his June 28 start at Boston, had thrown three quality starts since coming off the disabled list a month later.
It was the second-shortest start of his career, with the shortest coming June 20, 1995, when he gave up five runs in two-thirds of an inning in a game against Houston.
REPLAY: Pedro Martinez gave up six runs in the first inning and didn't come out for the second, complaining of a sore right calf muscle.
At no time did Martinez feel comfortable, and at no time were the Mets in Monday's 13-0 loss to the Phillies.
Jimmy Rollins hit a three-run homer, and Shane Victorino and David Dellucci also went deep for Philadelphia.
RHP Pedro Martinez gave up a career-high six runs in the first inning, the only frame he worked because of a strained right calf in Monday night's 13-0 loss to the Phillies. The Mets list him as day-to-day.
LF Cliff Floyd took an injection for his sore left Achilles tendon. He's currently on the disabled list and not ready to do anything baseball-related, manager Willie Randolph said.
Manager Willie Randolph said he's content with his corner outfield situation as of now, saying there's no sense of urgency to do anything. "In three weeks it could be a different story," he said.
C Ramon Castro, on the disabled list with a sore left ribcage muscle, could take batting practice off a tee Tuesday.
2B Chris Woodward was in the lineup Monday night, giving Jose Valentin a rest. Woodward has had only 11 at-bats since July 24. "When you're not playing, you have to make sure you work harder to stay ready," Woodward said. "If I didn't feel as if I wanted to play every day, I wouldn't want to be here."
RF Lastings Milledge entered Monday's game hitting .179 (5-for-28) since he was recalled Aug. 1 from Triple-A Norfolk, but he went 2-for-3. Manager Willie Randolph said the team hasn't considered sending him back to the minors for more seasoning.
BY THE NUMBERS: 3 -- Number of Mets with at least 74 RBIs.
