MIAMI (AP) Martin Prado's fifth hit of the game was a two-out double in the 11th inning that scored Christian Yelich from first base and gave the Miami Marlins a 6-5 victory over the New York Mets on Friday night.
The Mets tied the seesaw game with a run in the ninth but they stranded 13 runners, including three in the eighth and three more in the ninth.
Mets starter Jacob deGrom allowed nine hits and three runs in six innings. His ERA has climbed to 2.40 from 1.98 on Aug. 24, but he was in line for his 13th win before an uncharacteristically shaky showing by the bullpen in the seventh.
