SAN FRANCISCO -- Yusmeiro Petit had all of an hour to prepare for his spot start, and he hadnt thrown off a mound for seven days while only playing catch. 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," manager Bruce Bochy said of Petit. "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.

"The good news is we found a way to win. Thats the most important thing," he told reporters Friday. "And we all know were capable of being better. And we will (be). "But (goaltender) Carey Price was outstanding. He was tough to beat (Thursday night)." Despite the win, Therriens message was that his team has to be better in Game 2 of the second-round playoff series Saturday. Boston outshot Montreal 51-33 Thursday, climbing back from a 2-0 hole to force overtime. Price turned the surging Bruins back again and again, giving his team a chance to win. P.K. Subban obliged with the double-overtime winner. "We played against the best team in the league and you need goaltending," Therrien said. "Certainly Carey Price gave us that type of performance. He was phenomenal. Its good for the confidence of the team. "Like I said, we know as a team we could be better. We liked the way we finished the year. We liked the way we played the first round." Boston coach Claude Julien dismissed the idea that Price might get into his players heads. "Theres a lot of good goaltenders in this league," he said. "Weve got one (in Tuukka Rask). "And we basically still got three goals on him last night ... Weve just got to play our game and the chances are there. Im going to go back to what I said earlier -- bury those great opportunities. We played well, but there were a lot of open nets that we missed, there was a lot of chances that if we would have shot them properly, instead of panicking maybe, we get ourselves a goal." Therrien thought his team showed the rust of not having played since the April 22 completion of the Tampa Bay Lightning sweep.dddddddddddd But there were positives. The Montreal power play finally clicked, going 2-for-3 on the night with both goals coming from Subban. And the Canadiens, who managed 43 hits combined in the two games in Tampa, dished out 45 Thursday night in Boston. Still the Bruins outhit them 56-45 on the night. Asked about having to play a 12:30 p.m. ET start Saturday, Therrien laughed and said, "We had no choice." The Canadiens had a team meeting Friday and most of the players hit the gym. Therrien mixed up his lines during Game 1, with perhaps only the trio of Lars Eller, Brian Gionta and Rene Bourque standing out. "We tried to use them as much as we can in good situations, to help the team win." said Therrien. "But thats part of coaching," he added. "Sometimes you can not be afraid to make some changes." Thomas Vanek, who plays on the top line with David Desharnais and Max Pacioretty, has somehow become the poster boy for the need for improvement. "Theres a few players on our team who I believe need to step up our game regarding (Thursday night) and hes one of them," Therrien said of Vanek. "Im not here to mention any names but as a group weve got to be better and we will. "Im not worried and were glad that weve got Thomas Vanek in our lineup because he can be a dangerous guy to the other teams." Vanek, who was minus-one and did not have a shot in Game 1, did not shy away from the issue. "Last night as a line, even as a team, I dont think we played well. I think Carey carried us the whole game and then stole us the game. Subbie (Subban) stepped up and had a big goal. I think were not ignorant (of the need) for us being better as a line and myself as an individual." ' ' '
