Canning suffered the ailment when, after surrendering a batted ball to Atlanta shortstop Nick Allen, he attempted to change directions on the mound so that he could back up third base. He subsequently went down before being aided off the field by the Mets training staff.

PITTSBURGH — As of early Thursday evening, Griffin Canning was in the midst of putting together the strongest season of his injury-riddled career. By Friday afternoon, the Mets righthander was in surgery, repairing a ruptured Achilles that will cost him the rest of this year and a significant chunk of 2026, when he’s slated to become a free agent.
