CHICAGO -- The Giants' pitching has carried them all season. On Tuesday, it was the hitters' turn to get San Francisco into the win column.
Pat Burrell and Aaron Rowand each drove in three runs and the Giants enjoyed their highest-scoring game of the season, beating the Chicago Cubs 13-7 Tuesday in the opener of a day-night doubleheader for their sixth straight win.
The NL West leaders began the game as the lowest-scoring team in the majors. On a mild day at Wrigley Field with the wind helping the hitters, it was a perfect day for the Giants to break out.

Miguel Tejada also homered as the Giants surpassed their previous season high of 12 runs set June 2 at St. Louis.
"You couldn't ask for better weather," Rowand said. "Warm, not too hot. Good weather to play baseball in, being able to stay loose even though that was a long game. I think everybody swung the bat pretty well."
Burrell had three hits, including a homer, and scored twice. Rowand had two hits, including a three-run double, and also scored twice.
Ryan Vogelsong (6-1) got the win despite allowing a season-high six runs -- three earned -- and matched his high for the season with four walks in five innings.
"These guys came out swinging today," Vogelsong said. "It's a good thing because I didn't do a very good job of keeping them off the board. It was a great day for them to score a lot of runs."
Cubs starter Doug Davis (1-7) left after just 4 1/3 innings, allowing 12 hits, 10 runs and walking three.
"It was just one of them days," Davis said. "I feel like every time they hit the ball, it was where we weren't. Whether it was hard or soft, obviously we don't play anyone over the fence. It's just one of those days I can't really explain."
San Francisco jumped on Davis early, starting with Rowand's walk to lead off the game and Miguel Tejada's single. Rowand scored on Aubrey Huff's soft single to right-center, diving into the plate to barely beat the throw by center fielder Tony Campana.
Rowand set the tone with that first run, racing home after being waved in by third-base coach Tim Flannery.
"I expect them to send me on every ball until they tell me to stop," Rowand said.
Cody Ross singled to load the bases, meaning that the first four Giants had reached base. Davis recovered to get Pablo Sandoval to roll into a double play, which scored Tejada. Burrell tacked on a run with a two-out single.
The first-inning tally against Davis read: three runs, four hits, 24 pitches and a potentially long day for the Cubs' bullpen.
"He just struggled," Cubs manager Mike Quade said. "Just a tough day for Doug. We scored enough runs, we did enough offensively, we just didn't get a good start from him. Those things happen."
Vogelsong, who entered with a 1.86 ERA, hadn't allowed more than two runs since he gave up five against the Mets on May 3, a span of nine starts. The Cubs topped that in the second inning.
After Aramis Ramirez led off with a single, Pena homered into the right-field bleachers, pulling the Cubs within 3-2. It was Pena's eighth homer in his last 12 games and 17th since May 3, most in the National League.
With two outs the second, Hill hit a tying home run just inside the right-field foul pole. It was his second homer of the season and first since April 28.
Huff worked out a leadoff walk to start the third, then scored on Sandoval's double that just eluded right fielder Kosuke Fukudome. Burrell followed with his seventh homer for a 6-3 lead.
The Giants broke the game open and chased Davis from the game with a five-run fifth, highlighted by a bases-clearing double by Rowand. The five runs matched the best output in an inning for the Giants this season.
"They're a pitchable team," Davis said. "I think there's holes in everybody's swing if you're able to execute. Every hitter slumps, it's just a matter of when you get them. They were slumping before they got here, but today they broke out a little bit."
- Tejada hit his second homer of the season and first since April 8.
- The afternoon portion of the doubleheader was a makeup of a game rained out on May 15. The Cubs, who also played a makeup game against Colorado on Monday, played their third team in as many days.
- Cubs CF Marlon Byrd was hit by a pitch in his first rehab game for Triple-A Iowa. He been out since May 21 with facial fractures after getting beaned by Boston's Alfredo Aceves. The Cubs are hoping that Byrd, who walked, stole a base and scored two runs in five plate appearances for Iowa, will return to the lineup next week.
- Giants INF Mike Fontenot is still in Arizona at the club's spring training facility conditioning and will start a rehab game Thursday. Fontenot has been on the disabled list since May 26 with a left groin strain.
