MIAMI (AP) - Giancarlo Stanton hit a two-out grand slam to cap a ninth-inning rally by the Miami Marlins, who beat an angry Frank Francisco and the New York Mets 8-4 Sunday.

The walk-off victory was the second in the three-game series for the Marlins, who have won 10 of their past 12 games.

The Marlins trailed 4-2 when Emilio Bonifacio led off the ninth with his second triple of the game against Francisco (1-3). John Buck walked and pinch-hitter Greg Dobbs followed with an RBI single.

Francisco was then replaced, and he walked slowly toward plate umpire Todd Tichenor, hollering angrily. Manager Terry Collins stepped between Tichenor and Francisco, who waved his index finger and then his cap at the ump before finally heading to the dugout.
