PHILADELPHIA -- The New York Mets could have a problem at closer.

On Sunday, ninth-inning man Jenrry Mejia allowed three hits and two runs for his third blown save, resulting in the Mets' 7-6 loss to the Philadelphia Phillies.

In his last four appearances, Mejia is 0-2 with a 9.84 ERA. But struggles aren't the biggest issue.

After the loss, Mejia, already dealing with a calf injury, admitted that he's been pitching through a hernia injury, as well, that will require surgery after the season.

"Doctors say if it bothers me too much to let him fix it, but I don't want to let him know because I want to keep pitching," Mejia said. "I keep trying and throw my ball normal. It doesn't affect me."

Mejia said he's known about the hernia for three weeks and is receiving treatment.

"(Doctors) gave me some pills and some medication," he said. "If I don't feel normal, too much pain, they're going to make an operation. But I want to keep pitching. I want to take some pills and keep pitching. I think I can keep going. I'm ready to go."

Mets manager Terry Collins still has faith in his closer.

"He's done a great job. He's done an absolutely great job," Collins said. "The breaking ball is a little tumble-y right now. It's not as crisp as it normally is. That could be from wear and tear. There's nothing wrong with him physically. He's fine."

Mejia plans on gutting through it.

"Every time I come to the game I feel I want to keep going, do some treatment and keep pitching," he said. "Everything's OK. There's no excuse."
