The Mets optioned struggling right-hander Zack Wheeler to Triple-A Las Vegas on Saturday.

"They just pulled me in, like everybody else, and told me, 'You're going to Triple-A,'" Wheeler told reporters Saturday. "You take it kind of hard, because you're so used to being up here. It gives me a chance to go down there and just fine-tune some things and work on some things I need to work on to get back up here and be consistent.

"I really haven't proven myself this spring, so I sort of saw it coming, but I was hoping that it wouldn't. ... I really haven't done that much to help my cause."
