Rapid Reaction: Phillies 3, Mets 0

PHILADELPHIA -- At least it ended before the rain arrived.

After holding the Philadelphia Phillies hitless two outs into the fourth inning, fill-in starter Sean Gilmartin surrendered a double to Jeff Francoeur and a two-run homer to Darin Ruf. Using a makeshift lineup in the finale, the New York Mets proceeded to get swept in the three-game series with a 3-0 loss on Thursday. The game was played in front of the smallest paid crowd in Citizens Bank Park history -- 13,238, although the actual crowd was considerably smaller on the raw afternoon.

The Mets’ lead over the Los Angeles Dodgers for home-field advantage in their National League Division Series dipped to a half-game. The National League West champs play late Thursday afternoon at San Francisco. The Mets (89-70) own the tiebreaker over the Dodgers (88-70) by virtue of winning the season series.

Despite dropping three straight games in the City of Brotherly Love, the Mets went 14-5 against the Phillies this season. That matches the second-most wins ever by the Mets against one team in a season. Only the 1986 Mets exceeded that total when they went 17-1 against the Pittsburgh Pirates.

The Mets completed their road schedule with a 41-40 record.

Filling in for scratched starter Steven Matz (back spasms) in a game moved up seven hours to avoid predicted heavy rain, Gilmartin tossed a season-high 70 pitches in his first major league start. He allowed two runs on three hits and a walk in five innings and departed with the Mets trailing 2-0. Gilmartin worked as a starting pitcher in the minors before being selected in December by the Mets in the Rule 5 draft.

Tim Stauffer followed Gilmartin and contributed two scoreless innings. Dario Alvarez surrendered a solo homer to Andres Blanco in the eighth.

After a five-run first inning Wednesday, the Mets went scoreless during the final 17 innings of the series.

Phillies starter Jerad Eickhoff held the Mets to four hits and a walk while striking out 10 in seven scoreless innings. Kirk Nieuwenhuis had a pair of doubles against Eickhoff but twice was stranded in scoring position.

What’s next: The Mets complete their regular-season schedule with a weekend series against the Jonathan Papelbon-less Washington Nationals at Citi Field. Noah Syndergaard (Friday), Matt Harvey (Saturday) and Jacob deGrom (Sunday) are scheduled to have abbreviated starts.
