The Mets placed LHP Jason Vargas on the injured list on Monday due to a hamstring injury he suffered Sunday against the Brewers.
New York does not believe the injury to be considered serious, SNY's Andy Martino reports, and Vargas is eligible to return on May 16.
Vargas was lifted after four innings and 50 pitches on Sunday, a day after an 18-inning marathon game, due to "mild hamstring tightess."
With an off-day on Thursday, the Mets can make it through their next run through the rotation by using just four starters, but they will almost certainly need to patch together at least one start due to Steven Matz's injury -- with the team getting good news on Matz earlier Monday.
The Mets recalled Corey Oswalt from Triple-A Syracuse and activated reliever Justin Wilson off the injured list on Monday. They also optioned Tim Peterson to the minors.
Vargas said after Sunday's game that he felt he doesn't need to undergo an MRI, adding thathe felt the tweak in his hamstring on his final offering -- a pitch that struck out Brewers infielder Travis Shaw.
"I don't know if it was an unusual follow-through," he said. "But when my foot hit the ground I felt my hamstring grab me different than you normally feel it. I came into the locker room right away and tried to get things assessed as quickly as possible, just in case we had to go to the bullpen."
That proved to be necessary when it was decided Vargas' day was done. The bullpen -- Peterson, Daniel Zamora and Tyler Bashlor -- turned in four scoreless innings and allowed there baserunners.
