San Francisco, CA (Sports Network) - Juan Uribe led off the bottom of the eighth inning with a tie-breaking homer off Brian Sanches and Edgar Renteria added a two-run shot later in the frame, lifting the San Francisco Giants to a 6-4 win over the Florida Marlins.
Rookie Buster Posey had an RBI single in the third inning to extend his hitting streak to 20 games. Andres Torres went 3-for-4 and scored twice for the Giants, who won for the fifth time in six contests and moved within 2 1/2 games of San Diego for first place in the NL West.
Dan Uggla belted a pair of solo homers for the Marlins, who lost for just the third time in their last 11 games. Cody Ross added a two-run homer in defeat.
Both starting pitchers lasted seven innings with Florida's Josh Johnson allowing eight hits and three runs. Matt Cain gave up four hits and three runs, while logging six strikeouts.
The second contest of the four-game series was tied 3-3 until Uribe, who came into the game with 15 hits in his last 77 at-bats, stepped to the plate and crushed a 1-2 offering over the wall in left-center field for his 14th homer of the year.
Aaron Rowand singled with one out and Renteria followed with a homer to left field. Before the homers, Sanches (0-2) hadn't allowed a run in his last nine appearances, spanning a total of 10 innings.
Sergio Romo (4-3) retired the side in order in the eighth inning to get the win. Uggla homered off Brian Wilson with two outs in the ninth, but the right- hander fanned Wes Helms to end the game to pick up his major league-leading 30th save.
Torres doubled with one out in the third and scored on Aubrey Huff's two- bagger with two down. Posey then singled in Huff, but was thrown out at second base.
Ross homered to left in the fifth inning to tie it, but the Giants regained the lead in the bottom half when Freddy Sanchez singled in Torres.
Uggla homered to left leading off the seventh for his 20th long ball of the year.
Posey is just the seventh Giants player in the San Francisco era to have a hitting streak of at least 20 games. His streak is the second-longest by a rookie in San Francisco-era history behind Hall of Famer Willie McCovey's 22- gamer in 1959...The Marlins released pitcher Nate Robertson a week after designating him for assignment. The Marlins also designated minor league pitcher Kris Harvey for assignment...Johnson had gone 13 straight starts without allowing more than two earned runs, a streak dating back to May 8 when he surrendered three runs to the Washington Nationals. The only streak longer was Mike Scott's amazing 14-game run with the Houston Astros in 1986.
