SAN FRANCISCO Marco Scutaro homered off closer Santiago Casilla to lead off the ninth inning and lift the Colorado Rockies past the mistake-prone San Francisco Giants 5-4 on Tuesday night.
Scutaro smacked a 92-mph fastball from Casilla (0-2) just over the left-field wall for his first home run of the season after Colorado blew a three-run lead in the eighth.
Troy Tulowitzki, Michael Cuddyer and Carlos Gonzalez each drove in a run as the Rockies took advantage of three Giants errors to snap a four-game losing streak.
Rex Brothers (2-2) struck out Brandon Belt and Melky Cabrera with the bases loaded in the eighth. Rafael Betancourt struck out Nate Schierholtz looking with two on in the ninth for his seventh save in eight chances.
Solid outings by both starters were washed away.
Colorados Jeremy Guthrie allowed four hits and one unearned run in 5 1/3 innings in his first start since April 22. He had gone on the disabled list after falling off his bicycle on the way to the ballpark last month.
Tim Lincecum lasted seven innings, striking out seven and walking three for the Giants. At the very least, Lincecums lethargic starts this season finally disappeared.
Not much else about the final result did.
Gregor Blanco singled leading off the third, stole second and advanced to third on catcher Jordan Pachecos throwing error. He scored on Brandon Belts fly out to give San Francisco a 1-0 lead.
A night after taking a foul ball from teammate Dexter Fowler off his left leg, Tulowitzki played through soreness and singled in the fourth to score Carlos Gonzalez from second for the tying run. Gonzalezs one-out double that landed inches inside the left-field chalk was the first hit off Lincecum, who gave up little on a cold, foggy night under the lights in San Franciscos windy waterfront ballpark.
The Giants defense handed Colorado the rest.
Giants third baseman Joaquin Arias left in the fourth after a pitch hit his left forearm. X-rays showed no break, and the team diagnosed Arias with a bruise. Charlie Culberson replaced him at second, moving Emmanuel Burriss to third.
Burriss blew an infield pop by Tyler Colvin for what shouldve been the final out of Colorados fifth. He was charged with an error, but San Francisco caught a break when Pacheco who had reached on a double only advanced to third on the play. Jonathan Herrera flied out to center to end the inning.
The Rockies refused to let another gift go unwrapped.
Tulowitzkis line-drive single to center in the sixth rolled under the glove of a charging Angel Pagan, allowing the slow-footed Tulowitzki who mightve scored if healthy to easily jog to third on the error when the ball rolled all the way to the 399-foot sign. Cuddyer followed with an RBI double, and Pachecos sacrifice fly put the Rockies ahead 3-1.
The Giants added another error when catcher Buster Posey threw behind shortstop Brandon Crawford trying to nab Colvin at second. Gonzalez drove in Colvin from third with two outs.
Even still, San Francisco had its shots.
Cabreras two-run double off Josh Outman highlighted a three-run seventh for the Giants. Pagans two-out single against Matt Belisle evened the score at 4-all before Culberson struck out with Pagan at third.
