Pedro Martinez will make his final start of the regular season Wednesday, but he might not be a lock to start the Mets' playoff opener after all. Mets manager Willie Randolph backtracked Monday from an earlier pronouncement that his ace would start the Mets' first playoff game. Martinez is coming back from a calf injury and has made two starts since his return. "[Martinez] might need more time and get pushed back I said to you guys initially he might go in Game 1 ... but that's always subject to change," Randolph told reporters on Monday. "So what I am saying to you is that depending on how he comes out of his start [Wednesday], who knows? He might need to be pushed back a little. "
