Zack Wheeler will undergo Tommy John surgery next week and expects to be out of Major League games through the first two months of next season.

Wheeler said he had an ominous feeling when New York Mets chief operating officer Jeff Wilpon summoned him in the clubhouse Monday morning.

"When Jeff Wilpon came and got me, I sort of knew," Wheeler said. "I was like, 'Oh, man, it feels like I'm getting taken into the principal's office.' I sort of had a feeling that it wasn't good then. ... They told me on the phone, and I came out here and everybody was just sort of staring at me in this corner."
