SAN FRANCISCO -- The difference between batting in front of Buster Posey and further down the lineup is pretty basic, San Francisco Giants second baseman Joe Panik insists.

With Posey on deck, you take a 2-0 fastball and hope to get one step closer to setting up the team's top slugger.

But batting seventh, as Panik was Sunday, you take that same count and do the slugging yourself.

Panik highlighted an 18-hit attack with two home runs, leading the Giants to a 13-4 shellacking of the Atlanta Braves.

Madison Bumgarner benefited from the Giants' highest scoring game in more than two months, helping San Francisco post just its second series win since the All-Star break.

"It's good to take a series here. Just to take any series," Giants manager Bruce Bochy noted. "We haven't had many of these since the break."

The win also allowed the Giants to take the season series from the Braves after the clubs split the first six games.

Panik hit a solo homer in a two-run second inning that allowed the Giants to erase an early 1-0 deficit, then added a two-run shot in the fourth to get the San Francisco offense into high gear.

The home runs were the ninth and 10th of the season for Panik, who had his first multiple-homer game of the season. He later had a single and a sacrifice fly to finish with three hits and four RBIs.

The homers came with him ahead 2-0 and 3-1 in the count.

"You get pitched differently," Panik said he's noticed since being dropped from second to as low as eighth in the order this season. "You have to take advantage of your opportunities.

"It's a combination of things. Getting in some good counts, and not missing."

Denard Span had a second Giants homer in the fourth inning off Braves starter Aaron Blair, and San Francisco piled it on with an eight-run seventh against the Atlanta bullpen.

Eduardo Nunez had a solo homer and three Giants -- Brandon Crawford, Jarrett Parker and pinch-hitter Conor Gillaspie -- smacked triples in the seven-hit, seventh-inning explosion.

The 13-run total was the Giants' most since a 15-4 win at Pittsburgh on June 21.

"Good breakout," Bochy assured. "The balls were flying today."

The breakout included four homers, four triples and three doubles. No Giants team had ever previously had four triples and four home runs in the same game.

Equally important, Panik said, was the fact the Giants played their 13th consecutive error-free game.

"When it comes down to it, we're a pitching-and-defense team," he claimed. "That's going to carry us forward."

Bumgarner (13-8) won for the third time in his last four starts, allowing three runs and five hits in seven innings. He walked two and struck out five.

The All-Star left-hander has gone 7-0 in his last eight starts against the Braves.

Blair (0-6), who was called up from Triple-A Gwinett to make the start, allowed five runs and eight hits in four innings.

"I'm a pitcher that needs to be down in the zone and create movement," Blair said. "When I'm up, it's just flat. It goes a long way."

Braves interim manager Brian Snitker assured the rookie will get another shot in the rotation later this week.

"We'll keep working with him," he noted.

Crawford and Nunez joined Panik with three hits apiece for the Giants, who had been held to five hits in a 3-1 loss to the Braves on Saturday night.

Span, Parker and Brandon Belt added two hits each for San Francisco, which had 11 extra-bats hits in a game for the first time since 2002.

Freddie Freeman hit a two-run homer and Ender Inciarte had a double and a triple for the Braves, who had five extra-base hits among their six total hits.

Freeman's homer was his 27th of the season and seventh in his 21 career games at AT&T Park.

"We played good baseball for six innings," Freeman observed. "It kind of unfolded there in the seventh."

Gordon Beckham added a solo shot for the Braves with two outs in the ninth, his fifth home run of the season, to cap the scoring.

The homers gave the Braves 65 in their last 66 games.

The game had gotten off to a promising start for the Braves when Inciarte tripled leading off the first. It was just the second triple that Bumgarner ever allowed to the first batter of the game, and his fourth ever to a left-handed hitter.

Matt Kemp's sacrifice fly gave Atlanta a brief 1-0 lead.

The loss capped a 3-4 trip for the Braves, who haven't had a winning trip longer than five games this season.

The last major-league team to have four home runs and four triple in the same game was the New York Yankees in 1998. ...
