CHICAGO -- Pedro Martinez remains prominent on the Mets horizon, though it now appears that horizon almost must be identified as September. The Mets don't say so. Indeed, they say little about him that is touched with certainty. And, increasingly, the words they use to characterize his progress and status are measured. Most statements are qualified as they were not in June. It may be only corporate caution that has created the vagueness. And no one has said Martinez has taken a step in the wrong direction during his rehab. But the increasing lack of definition occasionally raises eyebrows, even those in the clubhouse. "We don't know anything -- at least I don't," one player said Friday. "We just know what we read. And you know Pedro makes his own schedule. But it just seems like with what you hear now, it's harder to tell when he's coming back. I know they're saying we're not counting on him. But it seems like they were a little bit. But not now so much." General manager Omar Minaya, who watched Martinez pitch in simulated game conditions in Port St. Lucie on Thursday, said Martinez's next activity -- the timing and the type -- is undetermined, though it is likely to be in a Minor League game. "But that can change," Minaya said. He characterized Martinez's performance with these words: "He didn't feel too comfortable at first. He was a little apprehensive ... I want to say it was a positive outing." He said Martinez could pitch again in "five, six or seven days" and that Martinez's velocity was about 85-86 mph -- about where it was last season.
