Jean Segura's three-run walk-off homer capped a dramatic ninth-inning comeback by the host Philadelphia Phillies, who deepened the New York Mets' misery by completing a four-game sweep with a 6-3 win Thursday.

The Phillies, who blew a 1-0 lead in the top of the ninth, trailed by at least two runs in all four games but took advantage of a Mets bullpen that gave up 17 runs in 11 1/3 innings during the series.

New York has lost five straight despite leading each game by at least two runs. It is the first time a team has lost five consecutive games in which it held a two-run lead since the Mets did so in 2011.

The Mets, who had one hit entering the ninth inning, seemed headed for a cathartic win when Todd Frazier hit a two-run homer with one out off closer Hector Neris. New York added a run when Dominic Smith and Wilson Ramos followed with singles before Smith scored on a groundout by Amed Rosario off JD Hammer (1-0), who got the final two outs of the inning.

But Mets closer Edwin Diaz (1-5) issued a leadoff walk to Cesar Hernandez. Maikel Franco followed with a game-tying two-run homer. After J.T. Realmuto struck out, Sean Rodriguez worked a pinch-hit walk and Scott Kingery singled to set up Segura's no-doubt blast into the left field seats.

Bryce Harper's sixth-inning homer, his 14th of the season, provided the only run of the first eight innings.

The Mets' ninth-inning comeback negated a strong effort from Phillies starter Aaron Nola, who allowed one hit and one walk while striking out 10 over seven scoreless innings. The only hit he gave up was a leadoff single in the sixth to opposing starter Zack Wheeler, who allowed one run on two hits and two walks while striking out seven over six innings.

The Mets finished 3-8 on a season-long 11-game road trip to fall a season-high eight games under .500.
