Edgar Renteria hit a go-ahead grand slam in the seventh inning and the San Francisco Giants pulled even in the NL wild-card race with Colorado, beating the Rockies 9-5 Sunday for a three-game sweep.
The Giants moved into a tie in the NL West with Colorado, six games behind first-place Los Angeles. The Rockies lost their season-high fifth in a row.
San Francisco swept the Rockies at home for the first time since April 8-10, 2005. Last week, the Giants lost three of four at Coors Field despite leading every game.
Renteria homered with two outs to overcome a 5-2 deficit, connecting two pitches after Rafael Betancourt (0-1) relieved Franklin Morales. Renteria hit his eighth career grand slam and second in two years against Betancourt.
Renteria came out for a curtain call from the sellout crowd of 42,571, the second time in two days it happened for the Giants - pitcher Barry Zito emerged to tip his cap during Saturday night's 5-3 win. Renteria also doubled in a run and matched his career high with five RBIs. He was intentionally walked in the eighth with two runners on.
Todd Helton and Troy Tulowitzki hit back-to-back solo homers in the fifth inning to put the Rockies ahead, but Colorado's bullpen couldn't hold a 4-1 lead.
Brandon Medders (3-1) recorded two outs in the seventh for the victory. Jeremy Affeldt struck out Garrett Atkins and Carlos Gonzalez with the tying run on third in the eighth, and the pitcher pumped his fist three times leaving the mound.
Closer Brian Wilson pitched the ninth after saving the first two games of the series, with fans chanting "Sweep! Sweep!"
