Young led off the eighth with a walk and advanced to third on a ground ball to Polanco at third. Alvarez was relieved by Chad Qualls, and Young scored on a passed ball to pull the Mets within 3-2.
"I was just playing the percentages, who was at third base and who was at first base," Young said of his alert baserunning. "I felt good about going."
David Wright singled, stole second, and advanced to third on a fly out. Dunn came in for Qualls and got pinch-hitter Josh Satin to fly out to left to end the inning.

"We lost a tough game, but we all laughed about the whole situation," Redmond said. "That was great. Classic." ... Before the game Redmond praised Hechavarria for being the best defensive shortstop in the National League. "I've not seen a better shortstop in this league than Hetch and hopefully he'll get the notoriety he deserves," Redmond said. ... RHP Matt Harvey (8-2, 2.11 ERA) will start the series finale for the Mets on Thursday against Marlins RHP Tom Koehler (2-6, 4.67 ERA).
