Shaun Marcum is cleared to make his next scheduled start for the Mets, but Carlos Torres will be on standby just in case.

Manager Terry Collins said before last night’s 5-3 loss to the Diamondbacks that Marcum has been bothered by soreness in his upper back and had recent tingling in his right hand that prompted an MRI exam on Tuesday.

“He said it’s the same stuff he had in spring training,” Collins said, referring to the stiffness in Marcum’s neck area that forced him to start the season on the disabled list. “But he pitched with it the other day. I don’t know what inning it started to bother him a little bit. So we thought we’d get him looked at. He’s fine.”

Marcum is expected to get the ball in Milwaukee on Saturday, but Collins plans to keep Torres rested the next two days in case something goes wrong.

Collins said he plans to curtail Marcum’s work between starts to keep him from incurring further stiffness.

“This is a recurring thing that’s happened since spring training and I wanted to get it looked at and fortunately the MRI exam came back clean,” Collins said. “So it’s a matter of well I don’t know if it’s massages, cutting back his sides in between starts that will help him keep that from getting stiff.”
