ATLANTA -- Noah Syndergaard, the Mets' top pitching prospect, appeared to be a lock to follow the same path as Matt Harvey and Zack Wheeler. The hard-throwing righthander had been expected to make his highly anticipated big-league debut sometime this season.

But manager Terry Collins said that may no longer be the case.

"There's a possibility you might not see him," Collins said before Tuesday night's game.

Syndergaard, 22, hasn't performed well enough thus far to warrant a promotion. He's 6-4 with a 5.35 ERA at Triple-A Las Vegas. He's also missed time with injuries to his right forearm and left shoulder. The Mets' overall pitching depth may also work against a promotion for Syndergaard.

So far, the Mets have been able to cover for injuries with other prospects such as Jacob deGrom and Rafael Montero. Veteran Daisuke Matsuzaka has been able to bounce between the bullpen and the starting rotation, as he has during Dillon Gee's absence.

While team officials have been reassured by Syndergaard's velocity -- it hasn't dipped despite his performance -- they also don't seem inclined to rush the pitcher. His chances of a promotion also may be affected by his innings limit.

"[Stuff] happens," Collins said. "I don't know any other way to put it. Injuries, workload, hasn't performed maybe the way we thought he was going to, there's all sorts of things. I don't have the answer for you. I just know right now there hasn't been a discussion of Noah Syndergaard or when he's coming."


Gee getting close

Gee (strained lat muscle) will make his next rehab start on Friday with Class-A Brooklyn. It will be his third rehab outing.

If all goes well, the Mets must decide whether to bring back Gee before the All-Star break or send him for another rehab start.
