Atlanta Braves first baseman Freddie Freeman (5) swings during the fifth inning of their baseball game against the San Francisco Giants at Turner Field, Saturday, June 15, 2013, in Atlanta.

ATLANTA - Freddie Freeman singled three times and drove in one run, Julio Teheran pitched six innings and the Atlanta Braves beat the San Francisco Giants 3-0 on Sunday night.

Atlanta won its second straight to take the three-game series and increase its NL East lead to 6 1/2 games.

San Francisco, the defending World Series champion, has lost 14 of its last 20 on the road, but the Giants remained 1 1/2 games behind Arizona in the NL West.

Braves closer Craig Kimbrel pitched a scoreless ninth to earn his 19th save in 22 chances. Kimbrel struck out Andres Torres and Joaquin Arias before retiring Nick Noonan on a flyout.

Freeman, who began the night hitless in 11 career appearances against Giants starter Tim Lincecum, singled in his first three at-bats and improved his average to .456 with runners in scoring position - third-best in the majors.

One night after he drove in the winning run off Giants closer Sergio Romo, Freeman made it 1-0 in the first when his RBI single scored Andrelton Simmons from second.

Freeman's single in the third moved Justin Upton to second. The next batter, B.J. Upton, drove in his brother Justin from second to put Atlanta up 2-0.

Teheran (5-3) allowed seven hits and one walk. The 22-year-old struck out eight and benefited from stellar plays by outfielders Jason Heyward and Justin Upton in the fourth, and by Simmons at shortstop in the sixth that kept a run from scoring with the Braves holding a two-run lead.

Lincecum (4-7) gave up six hits and five walks in six innings. Two of his three runs were earned, and he struck out three.

Torres, San Francisco's left fielder, hurt his team in the bottom of the sixth when Ramiro Pena's single appeared to bounce off his right foot and toward the wall.

Pena, who reached third on Torres' two-base fielding error, scored when pinch-hitter Jordan Schafer drove him in with a sacrifice squeeze bunt to make it 3-0.

Teheran struggled in his previous outing, a 7-6 loss at San Diego last Monday, but he beat the Giants for the second time in two starts against them since May 9.

Lincecum, a two-time NL Cy Young Award winner, dropped to 0-6 in his last nine starts and has a 6.69 ERA over that span.

Luis Avilan and Jordan Walden pitched scoreless innings for Atlanta in the seventh and eighth.

Jose Mijares and rookie Jake Dunning, who made his major league debut, held the Braves to one hit in the seventh and eighth.

Notes: Giants CF Angel Pagan said before the game that he's still hoping to avoid surgery on his left hamstring. Pagan took a platelet-rich plasma injection behind his knee last Sunday and is still unable to run the bases. He's missed 20 straight games with the injury. ... Braves manager Fredi Gonzalez said he still hasn't decided on a starter for the first game of Tuesday's doubleheader opposite Mets RHP Matt Harvey. Rookie RHP Alex Wood seems to remain a leading candidate, but Gonzalez said he might wait until after Monday's game against New York to announce his decision. LHP Paul Maholm will start the second game of the doubleheader opposite rookie RHP Zack Wheeler. ... The Giants' 6-5 loss Saturday was their first when leading after eight innings since July 4, 2012 at Washington. ... San Francisco 3B Pablo Sandoval, on the disabled list with a strained left foot, holds a narrow lead over Mets 3B David Wright in balloting for the July 16 All-Star Game in New York.
