ANAHEIM, Calif. – Colin Holderman, who was placed on the 15-day injured list with a right shoulder impingement, will undergo imaging on his right pitching shoulder when the Mets return to New York, Buck Showalter said Sunday.

Holderman was placed on the IL Saturday, retroactive to June 8.

Holderman, who came up from Triple-A Syracuse this year and has been a key piece in the Mets' bullpen, has 14 strikeouts in 11 games. But he struggled in his last appearance against the Padres Tuesday, allowing three runs on a hit and three walks to inflate his ERA from 0.82 to 3.18. He was doing his throwing program on Saturday and shut it down after four or five pitches when he felt discomfort. Holderman has dealt with a shoulder impingement in the past, Showalter said.

“You know how much it means for him to be pitching up here,” Showalter said. “I think he’s had some similar stuff and I think because of his history, his knowledge of it, he just didn’t want it to turn into something a lot worse. I’m hoping that’s what it was, just a cautionary thing on his part.”

Starling starting 

Starling Marte (left quad tightness) made his return to the lineup Sunday night after getting pulled from the game Tuesday when he injured himself attempting to steal a base. He played right and batted second.  

“Happier with me than he was yesterday,” Showalter said of Marte, who had spent the previous days petitioning his manager to get back to playing. “We could have pushed him the last couple days … We’d like for him to get a feel before the off-day, too, but he’s ready to go … I feel very confident.”


Peterson to start

David Peterson is slotted to start on Wednesday against the Brewers after the Mets skipped his last start. Peterson last pitched 2 2/3 innings of relief Friday, after Tylor Megill’s shortened start. With Megill returning from right bicep tendinitis, and the Mets coming off a monster 10-game, 11-day road trip, Showalter will get the big righthander an extra day of rest. He’ll pitch Thursday.
