Wheeler (elbow) tossed 17 pitches in his lone inning of during a rehab game Saturday with High-A St. Lucie. He surrendered one walk and an unearned run.
Wheeler, who was making his first appearance in a game since March 2015, was originally scheduled to work two innings, but a rain delay ended up nixing those plans. It was an encouraging outing nonetheless for the right-hander, whose fastball sat between 90 and 96 miles per hour during the game, according to ESPN.com's Adam Rubin. The Mets are hoping to have Wheeler back by September, but he could face strict innings limits as the team gears up for a potential postseason run.
