Dillon Gee to DL with lat strain

NEW YORK -- Just as the New York Mets were prepared to show off one of their young pitchers, they lost one of their most established starters.

The Mets announced Wednesday that right-hander Dillon Gee has been placed on the 15-day disabled list (retroactive to May 11) with a strained right lat muscle. Gee said he felt unusual soreness after his last start, Saturday against the Philadelphia Phillies, and that it got worse after he threw in the bullpen Tuesday. The Mets are hopeful Gee will miss only two starts.

Rookie right-hander Jacob deGrom, called up this week to join the bullpen, will instead take Gee's spot in the rotation and start Thursday night's Subway Series finale against the New York Yankees.

The Mets already started rookie Rafael Montero in Wednesday night's 4-0 loss against the Yankees. Now, they'll have two pitchers making their major league debuts on back-to-back nights.

"We now have two guys in the rotation who weren't in the rotation yesterday," Mets general manager Sandy Alderson said. "What was once tremendous depth is now getting more and more shallow in terms of resources."

The Yankees also will have a pitcher making his big league debut Thursday, right-hander Chase Whitley. Coincidentally, the last time two starting pitchers debuted opposite each other in an MLB game came Sept. 7, 2010 -- Gee against the Washington Nationals' Yunesky Maya.

The Mets have never previously had starting pitchers make their major league debuts in consecutive games.

Gee has been the Mets' most consistent starter, going 3-1 with a 2.73 ERA in eight starts. The 25-year-old deGrom was 4-0 with a 2.58 ERA in seven starts for Triple-A Las Vegas.

Gee had an MRI exam Wednesday, and doctors told him that he had no structural damage. Even so, he felt enough pain that he told the Mets he couldn't pitch.

"It's soreness I've never had before," Gee said. "A lot more than normal, and it just didn't go away."

Gee said he had no issues before the start Saturday, and manager Terry Collins said the lat problem didn't factor into his decision to remove Gee from that start after just 81 pitches. Gee told the Mets that he isn't even sure when the injury occurred.

When Gee felt more soreness after his Tuesday bullpen session, the Mets told deGrom to be ready to possibly start Thursday. They waited until Wednesday to make the decision official.

"We're all pretty disappointed," Collins said. "At the same time, we wanted to see [deGrom]. Now we'll get a chance to see him pitch."

Gee will be put on medication to relieve the strain, and the plan is for him to try to throw early next week. If that goes well, he could return from the DL when his 15-day stint is up.

In other news, Mets catcher Travis d'Arnaud underwent concussion tests after he was hit in the head by Alfonso Soriano's backswing Tuesday night. Alderson said d'Arnaud, who stayed in the game, felt symptoms Wednesday after some light exercise and the team was concerned they could be related to a concussion.

Mets closer Bobby Parnell was transferred from the 15-day disabled list to the 60-Day DL, opening a spot on the 40-man roster for Montero. Parnell is out for the season following Tommy John surgery.
