Has Marcum endangered rotation spot?

NEW YORK -- Terry Collins said the Mets are not close to bouncing a starting pitcher from the rotation with Zack Wheeler's impending arrival, because the club will go with a six-man rotation for a couple of turns.

But what if Dillon Gee and Jeremy Hefner continue to produce and Shaun Marcum doesn't? Could Marcum ultimately lose his spot, despite a $4 million base salary and incentives?

Marcum was charged with six runs in 5 2/3 innings Friday in a 6-3 loss to the Cubs that dropped him to 0-8. He has a 5.43 ERA.

"When it comes down to the time to make the decision, certainly I'm not sure salary is going to have anything to do with it," Collins said. "I think we're going to take the five guys that we need to make sure are the best five to go out there. ... I think Shaun, he's a professional. He knows you've got to go out and get the job done. He's very upset about the way he pitched tonight, but he has pitched very well. He had a bad start."

Said Marcum: "I really haven't thought about it."

WRIGHT SIDE: David Wright said getting thrown out going first-to-third in a two-run seventh was an acceptable risk.

"One out, you want to try to get to third," Wright said. "I think it's the right play. I'll do it again."
