NEW YORK -- Jose Reyes returned to the Mets' clubhouse Tuesday before the team's game with the Phillies. When Reyes returns to the lineup, however, is still up in the air.

Reyes was placed on the disabled list on May 26 -- retroactive to May 23 -- with tendinitis in his right calf. The shortstop pulled himself out of a rehab stint in Port St. Lucie, Fla., after trying to beat out a ground ball to second base. A subsequent MRI revealed a small tear in his hamstring.

"I felt it down my leg," Reyes said. "It wasn't a good feeling for me."

It was just the latest setback for Reyes, who expected to miss only one game with the calf injury. Instead, he didn't start five straight contests from May 14-18, then pulled himself from a game in Los Angeles on May 20. He hasn't been back in the lineup since.

"I'm a little frustrated, because I'd like to be on the field," Reyes said. "It is what it is."

Reyes was at Citi Field to receive a cortisone shot and treatment on the hamstring. The team has yet to set a timetable for his return.

"They don't say about time. When I feel ready to go, I'll be able to play," Reyes said.

Reyes had hamstring issues early in his career, playing just 53 games in 2004 because of various injuries. The Mets tried to alter his running style in order to alleviate the problem.

Reyes maintains, however, that this is a different -- and less serious -- injury.

"The good news is, when I hurt my hamstring before, I wasn't able to walk the way I wanted to," Reyes said. "And now with this one, it's different because I can walk."

The Mets have used Alex Cora, Ramon Martinez and Wilson Valdez in Reyes' absence, but that trio hasn't been immune to the injury bug that has plagued the team over the past month. Cora spent time on the disabled list with a torn ligament in his thumb, while Martinez was placed on the DL on Tuesday with a broken finger.

Since returning to the starting lineup Wednesday, Cora has shared Reyes' leadoff duties with second baseman Luis Castillo.
