JoJo Romero entered after Arrieta departed and retired Wilson Ramos on a double-play grounder, with first baseman Alec Bohm making an excellent, backhanded pick.

Romero tossed two innings, Tommy Hunter got two outs and Hector Neris finished for his fourth save in seven chances.

“Our bullpen did an outstanding job today,” Phillies manager Joe Girardi said.

Mets starter Rick Porcello (1-5) yielded four runs and six hits in six innings as New York (21-27) lost its third straight and fell six games under .500, matching a season low.

Porcello retired the first two batters in the fourth before he walked Jean Segura. Scott Kingery lined a double to right and Andrew Knapp walked. Pinch-hitter Adam Haseley then lined a single to left-center for a 2-0 lead.

Nimmo answered quickly, driving Arrieta’s first pitch in the fifth out to right to cut it to 2-1.

“Everyone is a little down right now as I think is appropriate,” Nimmo said. “We definitely wanted to come out and get a win today because we really need to win series from here on out.”

Gregorius connected in the fifth, launching one off the video board on the facing of the second deck in right. Bohm had reached on an infield single when third baseman J.D. Davis nearly made a sensational play. Davis’ glove and the ball went flying in the air as he tried to short-hop the sharp grounder. Davis looked up, saw the ball coming down, snagged it and fired to first too late to get Bohm.
