Zack Wheeler, who started the season in the minor leagues, is now arguably the Mets third best starter behind Jacob deGrom and Noah Syndergaard.

Matt Harvey has been moved to the rotation, Jason Vargas has been hurt and was lit up like a candle in his first game back, and Steven Matz is a ball of a uncertainty each time out.

Part of the success Wheeler has seen is due to a new pitch that him and pitching coach Dave Eiland have worked on.

On Sunday, the right-hander labored through a 30-pitch first inning, but rebounded nicely, turning in five strong frames with nine strikeouts.

His new pitch, a changeup he’s been throwing with a new grip, has great downward plane and elicits a lot of swings and misses. Check it out below:

“I still don’t know what I call it,” Wheeler said. “Me and Dave have been working on a little split, split-fastball, split-change . . . It was working in the bullpen the other day, so I just carried it into the game.”

For Wheeler, he will look to build upon his strong outing and lower his 4.09 ERA through 22 innings.
