Luis Castillo's RBI single with two outs in the bottom of the ninth lifted the New York Mets to a 6-5 walk-off victory over the Florida Marlins Tuesday night.

Angel Pagan collected four hits and scored three runs while Carlos Beltran and Jeff Francoeur drove in two runs apiece for the Mets, who won for just the second time in 49 tries this season when trailing after seven innings.

Ike Davis led off the ninth with a single off Will Ohman (0-2) and moved to second on Josh Thole's one-out hit. Pinch-hitter Mike Hessman struck out before Castillo - Florida's all-time hits leader - singled to shallow right field, plating Davis and giving New York its fifth walk-off win of the year.

Hisanori Takahashi (8-6) notched the victory after tossing a scoreless top of the ninth.

Florida rallied from a 4-2 deficit against R.A. Dickey in the seventh to take the lead. Brett Hayes and pinch-hitter Emilio Bonafacio opened the inning with singles and Gaby Sanchez deposited Dickey's first offering deep into the left-field seats two outs later for his 15th homer of the season and a 5-4 edge.

After the Mets grabbed a 1-0 lead in the second, Sanchez and Uggla hit back-to-back sacrifice flies in the third to put the Marlins in front.

Sanchez has collected three homers and 13 RBIs in his last seven games.

Pagan scored on an error in the bottom of the third to tie it at 2-2. Beltran's RBI single in the fifth put New York ahead and Francoeur added his second sacrifice fly of the night later in the inning for a 4-2 advantage.

Pagan and Beltran struck again in the eighth to again forge a tie. Pagan's hustle turned a single into a double with two outs and Beltran followed with an RBI single to make it 5-5.

Dickey allowed five runs on 10 hits in seven innings for New York, while Florida ace Josh Johnson allowed four runs - three earned - in just five innings.
