Mets starting pitcher prospect Noah Syndergaard was expected to make his major-league debut in 2014, but he never made it to the majors after having an up-and-down year in the minors.

Syndergaard said Wednesday he didn't deserve a promotion, as he struggled due to an over-reliance on his fastball, per ESPN.

"Being in Triple-A, you’ve got guys who have been in the big leagues for a number of seasons. So they can hit a fastball," Syndergaard said. "Hitting is timing, and pitching is throwing off timing. If you throw three fastballs on the heart of the plate, they’re going to time one up."

Syndergaard appears headed back to the minors to start the 2015 season since the Mets have a logjam of starters at the major-league level. Still, Syndergaard's long-awaited MLB debut might finally happen this season.

“I try not to pay attention to that,” Syndergaard said. “We all have a goal in mind, and that’s to help the Mets get some victories. And I just pay attention to whatever is in my control."
