Zack Wheeler gets up for the Mets more than any other team. Wheeler was a mainstay in the Mets' rotation the previous two seasons, but was highly disappointed when the Mets let him walk in free agency without ever making an offer.
Wheeler landed with the Phillies and has thrived going 4-0 with a 2.20 ERA. He beat the Mets in mid-August, 6-2, allowing two runs on six hits in seven innings. 
The Mets are going with David Peterson, who has yet to make his mark. 
Philadelphia has won the past seven times it was favored.
