PHOENIX — David Peterson received no love from his defense, particularly third baseman Andy Ibáñez, but he did his part to give the Mets an opportunity to win Sunday. The lefty, who has been placed in the bullpen to work as a bulk reliever, pitched five innings without allowing an earned run in the team’s 5-1 loss to the Diamondbacks . All three runs that scored with Peterson on the mound followed Ibáñez’s second throwing error of the day, in the sixth inning. “I think it’s just getting back to who I am as a pitcher, getting the sinker down, and using the four-seamer,” said Peterson, who owns a 5.49 ERA. “I feel like I have had better feel the last couple of outings with the changeup and the sliders continue to be good.” David Peterson throws a pitch during his May 4 outing against the Rockies.
