Pagan homered to start it off for the Giants. Blanco hit a two-run shot in the second. The Giants had another breakthrough in the fifth, when back-to-back doubles by Joaquin Arias and Pagan ended an 0-for-14 slump with runners in scoring position during the series.
Sandoval's two-run shot in the seventh made it 8-3, matched the Giants' season high for homers and drew loud boos from the crowd of 44,375 — the third-largest at Great American Ball Park. Fans quietly settled into their seats and used their white rally towels as lap warmers against the evening chill.
The Giants normally don't hit many homers — only 103 during the season, fewest in the majors. They're only the seventh team since 1900 to reach the playoffs after finishing last in the majors in homers.
While the offense went to work, Lincecum bailed out the bullpen.
Bochy didn't hesitate to put the guys he wanted on the mound, using four pitchers in the first four innings. Lincecum settled things down, giving up only two hits in his second relief appearance of the series.
He threw 42 strikes out of 55 pitches and even batted twice — just like a starter.
"The last two games, it's been about scratching and leaving it on the field," Lincecum said.
Bochy decided to go with left-hander Barry Zito over Lincecum for Game 4 because he was better down the stretch. Zito was left off the postseason roster when San Francisco won the World Series in 2010, but finished the regular season with seven straight wins.
The left-hander lasted only 2 2-3 innings, his shortest career outing in the postseason. On came Lincecum to save the day.
The Reds finished with the second-best record in the majors at 97-65, one game behind Washington. The rotation was the foundation of their championship season, with all five starters making it through healthy — a franchise first.
Things changed dramatically when Cueto had to leave the first inning of the playoff series opener on Saturday with the injury. The Reds made it through that game with Latos filling in for a 5-2 victory, but couldn't win without him on Wednesday.
NOTES: The Reds honored RHP Homer Bailey on the field before the game for his no-hitter in Pittsburgh on Sept. 28, presenting him and C Ryan Hanigan with framed photo montages. ... It was Zito's shortest outing since he lasted 2 1-3 innings on Aug. 29 at Houston. The Giants won it 6-4. ... San Francisco has won each of Zito's last 12 starts. ... Leake lasted 4 1-3 innings, giving up six hits and five runs. ... The Giants hit three homers in a game eight times during the regular season.
