Marlins 2, Mets 1 (20): Adeiny Hechavarria delivered an RBI single with one out in the top of the 20th inning to lift visiting Miami to a marathon win.

The tiebreaking hit helped the Marlins improve to 7-3 against New York, compared to 10-41 against all other teams, and was part of a frustrating day and night for the Mets, who lost star right-hander Matt Harvey to lower back tightness after seven innings and finished 0-for-19 with runners in scoring position, a franchise record.

Placido Polanco and Rob Brantly both singled with one out in the 20th against Shaun Marcum (0-7), a starter who was in his eighth inning of relief. Hechavarria then dropped a base hit into center to snap the tie, and Marlins closer Steve Cishek retired the side in order in the bottom half to record his sixth save.

Kevin Slowey (2-5), like Marcum originally scheduled to make a start in the series before a rainout Friday forced the teams to shuffle their rotations, got the win after throwing seven scoreless innings of relief. Harvey allowed a run and six hits in seven innings but left after throwing warmup pitches for the eighth.

Juan Lagares gave New York an early 1-0 lead with an RBI double in the second. Chris Coghlan's sacrifice fly tied it in the fourth, and that's where the score stayed until the Marlins ended the 6-hour, 25-minute affair.
