PHILADELPHIA (AP) — Jimmy Rollins hit an RBI single to lift the Philadelphia Phillies to a 4-3 victory over the San Francisco Giants in 12 innings Sunday.

John Mayberry Jr. hit two solo homers for the last-place Phillies, and Nate Schierholtz hit a pair of solo shots for the NL West-leading Giants.

The Phillies snapped a seven-game home losing streak and avoided their first sweep against the Giants since 2004.

Brad Penny (0-1) walked Carlos Ruiz with one out in the 12th. Laynce Nix followed with a single to right to move Ruiz to third. Rollins then lined the first pitch to right to end it.

The five-time defending NL East champions are 10½ games behind Atlanta in the wild-card standings.

Kyle Kendrick (4-8) tossed 2 1-3 innings to earn the win and extended his career-best scoreless streak to 18 2-3 innings.

Phillies starter Joe Blanton gave up three runs and seven hits in eight innings, increasing his trade value with another strong second-half start. Since 2008, Blanton has the best record in the majors after the All-Star break at 17-5.

The right-hander will be a free agent after the season, so the Phillies might move him before the July 31 non-waiver trade deadline unless they start to make a run.

San Francisco’s Barry Zito allowed three runs and five hits, striking out seven in seven innings. Zito is having his best season for the Giants since signing a $126 million, seven-year contract in December 2006.

After Mayberry gave the Phillies their first lead, 3-2, on his second homer in the seventh, Schierholtz answered with his second in the eighth. He hit a high drive to right to tie it at 3.

Blanton escaped further trouble in the inning when right fielder Hunter Pence saved two runs by making a running basket catch on Buster Posey’s deep fly to right.

Mayberry drove a 3-2 pitch into the seats in left to tie it at 2 in the fourth. He hadn’t driven in a run in his previous 39 at-bats, going back to June 24.

Pablo Sandoval’s RBI double to left-center gave the Giants a 2-1 lead in the fourth.

Schierholtz ripped a 2-0 pitch way out to right for his first career leadoff homer to give the Giants a 1-0 lead.

Chase Utley’s RBI triple in the bottom half tied it at 1. Zito escaped a first-and-third, one-out jam by getting Pence to ground into his 13th double play.

Zito stranded runners on second and third in the third by striking out Ryan Howard on a 74 mph curveball.
