Monday night in the series opener against the Diamondbacks, they looked to Zack Wheeler as the stopper. That's a lot to ask for a guy who when he came into spring training the Mets thought would not even be pitching in the majors at this point. Wheeler, who had a setback-plagued two-year recovery from Tommy John surgery, was expected to rejoin the team later in the season because of an innings limit. He was solid Monday, throwing six innings and allowing one earned run on seven hits with six strikeouts in a 7-3 loss.
