MIAMI (AP) _ Cliff Floyd had four hits and a career-high six RBIs, including his first career grand slam, and Reid Cornelius won his first game in nearly three months as the Florida Marlins beat the Philadelphia Phillies 11-5 on Saturday.

Floyd's 421-foot shot to right-center field broke open a close game in the sixth inning. Leading 5-4, the Marlins loaded the bases with none out before Floyd hit his 22nd home run of the season off reliever Thomas Jacquez.

Cornelius (4-10) picked up his first win since July 2 at Montreal, allowing three runs and six hits in four innings. Cornelius took over for starting pitcher Jesus Sanchez after a 1 hour, 28-minute rain delay between the second and third innings.

Philadelphia's Robert Person (9-7) allowed five runs and 11 hits over five innings. The Marlins had 17 hits, tying their season high.

The Phillies took a 2-1 lead in top of the fourth inning after Bobby Abreu scored on a double by Brian Hunter.

The Marlins answered with three runs in the bottom of the fourth. Preston Wilson scored on a sacrifice fly by Nate Rolison. Mike Lowell doubled and scored on a double by Ramon Castro, and Cornelius helped his own cause when he executed a squeeze play, scoring David Berg to give the Marlins a 4-2 lead.

After loading the bases with none out in the fifth, Person was lifted for Jacquez. The Marlins made it 5-2 after Floyd scored on a sacrifice fly by Rolison, his second of the game.

A two-run home run by Pat Burrell, his 18th, pulled the Phillies to 5-4 in the sixth inning.

The Phillies took a 1-0 lead in the first. Doug Glanville led off with a double, advanced to third on a ground out, then scored on a sacrifice fly by Abreu.

The Marlins tied it in the second after Lowell led off with a double, took third on a groundout and scored on a sacrifice fly by Berg. ^Notes@: Rolison picked up his first two career RBIs with the sacrifice flies.
