MIAMI (AP) _ Rich Aurilia hit a three-run homer with one out in the ninth inning and the San Francisco Giants came from behind twice to beat the Florida Marlins 11-9 Wednesday night.

Trailing 9-7, the Giants started the ninth with singles by Barry Bonds, Jeff Kent and pinch hitter Felipe Crespo to score a run against Antonio Alfonseca (0-1). Following a forceout, Aurilia hit his first homer on the first pitch.

The Giants overcame a 5-4 deficit on Kent's three-run homer in the fifth. They blew leads of 3-0, 4-1 and 7-5.

The sloppy but exciting game drew a crowd of 8,365, the smallest at Pro Player Stadium in the Marlins' eight-year history.

John Johnstone (1-0) gave up one run in 1 1-3 innings. Robb Nen pitched a perfect ninth for his second save.

Florida scored three runs in the seventh and took advantage of a two-out passed ball on a strikeout to take an 8-7 lead. With the score 7-all, Mark Kotsay swung and missed on a 2-2 pitch from Felix Rodriguez, but the pitch glanced off catcher Bobby Estalella's glove and sailed over his head to the backstop.

The Marlins made it 9-7 on Derrick Lee's RBI single in the eighth, their 12th hit. San Francisco had 15 hits.

Kevin Millar had a two-run homer and an RBI single for the Marlins.

The Giants scored three in the first against Vladimir Nunez. Bill Mueller doubled, Bonds walked and Kent doubled home a run. Ellis Burks hit a sacrifice fly, and J.T. Snow drove in a run with a two-out single.

San Francisco added an unearned run in the second. Estalella doubled, took third when Nunez bobbled a sacrifice bunt for an error, then scored on Marvin Benard's groundout.

Luis Castillo led off Florida's first with a triple and scored on a two-out single by Mike Lowell. Mike Redmond led off the second with his first triple in 364 career at-bats, then scored on Nunez's groundout.

Florida tied the game in the third when Cliff Floyd singled and Millar homered on a 3-2 pitch with two out.

The Giants' Kirk Rueter walked the bases loaded in the fourth and was replaced by Aaron Fultz, who walked Preston Wilson to give Florida a 5-4 lead. Kent homered in the fifth to put the Giants ahead 7-5.
