Mets LHP Jon Niese will have meniscus surgery on his left knee on Thursday, the Mets announced. R
Rookie Robert Gsellman will take his next turn in the rotation this Sunday, manager Terry Collins said.
Niese was placed on the 15-day disabled list after he left Tuesday's start against the Cardinals after four batters.
Gsellman threw 3 2/3 scoreless innings of relief after Niese left the game
The Mets called up RHP Erik Goeddel to take Niese's spot on the 25-man roster.
Niese said he has experienced pain in his knee since June, including his prior start in Arizona. He told reporters he felt no pain warming up in the bullpen before Tuesday's start, but felt a pop and a shooting pain down his left leg during the game.
"It progressively got worse and worse," said Niese, who has an 11.45 ERA in six appearances for the Mets this season. "Every pitch, there was just a sharp, shooting pain down my leg. … I've got to get it fixed. I can't keep going out there like that."
Gsellman went 4-9 with a 3.99 ERA in 20 atarts with Double-A Binghamton and Triple-A Las Vegas before he made his MLB debut on Tuesday. Gsellman, 23, struck out 88 batters in 115 innings pitched.
On Tuesday, he allowed two hits, three walks and two strikeouts in 3 2/3 innings.
"It did happen pretty fast," said Gsellman, who had five minutes to warm up before entering the game with runners on base and Yadier Molina at the plate. "But, I slowed myself down by taking a couple breaths and that helped out a lot. I was a little nervous."
