SAN FRANCISCO -- Tim Lincecum struck out 11 in his best start of the year, Tyler Colvin backed him with a home run and go-ahead, two-run triple in the seventh inning and the San Francisco Giants beat the Atlanta Braves 4-2 on Monday night. Lincecum (3-2) left to a roaring standing ovation after pitching a season-high 7 2-3 innings in his first start of eight getting past the sixth. B.J. Upton hit a tying solo homer in the fifth, then was caught stealing on replay review as the potential go-ahead run in the top of the seventh. Upton hit a one-out double and was ruled to have stolen third on a slide below a reaching Pablo Sandoval. Giants manager Bruce Bochy challenged the call by third base umpire Dana DeMuth, and it was overturned in 2 minutes, 7 seconds. San Francisco, coming off a 7-3 road trip to Atlanta, Pittsburgh and Los Angeles, won for the sixth time in seven home games. Atlanta had won three in a row. Lincecum struck out 10 or more for the 36th time in his career and first since last July 28 against the Cubs. He retired Chris Johnson on a swinging strikeout to end the sixth with runners on first and second. Promoted from Triple-A on Saturday, Colvin splashed a solo homer into McCovey Cove beyond the right-field arcade in the second -- the 65th Giants homer to reach the water. Brandon Crawford had the other this season, on April 13 against Colorado. Giants leadoff man Angel Pagan produced his fourth three-hit game of the season. Javier Lopez surrendered Freddie Freemans ninth-inning splash homer, then Sergio Romo finished for his 13th save. It marked the first game with two splash homers since Barry Bonds did it by himself on May 18, 2002. Gavin Floyd (0-1) remained winless after his second start of 2014. Floyd struck out eight over 6 1-3 innings in his first outing against the Giants since 2008.

There was no time to study San Diegos hitters, either. Petit dazzled in place of injured ace Matt Cain, pitching six innings to lead the San Francisco Giants past the Padres 6-0 Tuesday night. "Thats my job," said Petit, who was one out from a perfect game last September against Arizona shortly after joining the rotation. "Im prepared for it any time for that, one moment before the game telling me youre going to start the game. Ive done it before. Its normal for me." Angel Pagan led off the first inning with a homer and Buster Posey connected two batters later to give Petit an early boost. Cain was scratched after cutting the tip of his right index finger. Cain was in the clubhouse kitchen making a sandwich and had a knife in his hand when the utensil dropped. Cain tried to catch it and cut his finger about a half-inch at the tip. He took batting practice, but then tried to throw and kept opening the cut. He expects to make his next start, Monday at Pittsburgh. "Its obviously really, really bad timing," Cain said. "Petit did an unbelievable job today. He picked it up and the guys scored a bunch of runs. Hopefully this isnt a big deal ... and it should be fine in a couple days." Petit (2-1) didnt allow a hit until Everth Cabreras leadoff single in the fourth. Hector Sanchez, starting at catcher with Posey at first base, hit a two-run single and a sacrifice fly. Petit allowed three hits with four strikeouts and no walks. It was his first start not allowing a run since he tossed a one-hitter last Sept. 6 at home against Arizona. He lowered his ERA from 3.68 to 2.61. Jean Machi pitched two innings and Santiago Casilla finished the 2-hour, 28-minute, three-hitter, San Franciscos second shutout this season. The Padres were blanked for the fourth time. The Giants said Cain wouldnt require stitches. "What a great effort," mannager Bruce Bochy said of Petit.dddddddddddd "Any time you lose your starter and the swing guy goes in there and gives you six innings like that, thats such a big lift for the club." Cain, who pitched a perfect game two years ago at AT&T Park, will finish winless in April. He is 0-3 with a 4.35 ERA in five starts. Pagan sent a 1-1 pitch from Eric Stults (1-3) just inside the left-field foul pole for his second homer, then Posey hit his sixth one out later. It was Pagans seventh career leadoff homer and first since May 1, 2013, at Arizona. The Giants hit two homers in the first inning at AT&T Park for the first time since Fred Lewis and Bengie Molina did so on July 22, 2008, against Washington. "Tonight I didnt execute many pitches. I was down in the zone the first time I played them," Stults said. "I knew they were probably going to be aggressive. They usually come out swinging early." Stults was done after 2 2-3 innings, allowing five runs and seven hits. San Diegos Yasmani Grandal made his first career start at first base as manager Bud Black gave struggling Yonder Alonso a break. San Diego will try to win Wednesdays rubber game for their first road series victory this year and snap a nine-series winless streak at AT&T Park dating to a three-game series here from Oct. 1-3, 2010, one that sealed the Giants division title on the way to the citys first World Series championship.
