Giants rally against Clayton Kershaw, then Kenley Jansen in 7-4 win

See, all things are possible.

The Dodgers were up by a run in the seventh inning, the Giants had a runner at second base, ace Clayton Kershaw got ahead in the count 0-2 on San Francisco’s Brandon Hicks and he promptly gave up a two-run homer. And some day there really will be flying cars.

But wait, there’s more!

The Dodgers rallied with two outs in the bottom of the ninth inning on a two-run homer by Hanley Ramirez, and then closer Kenley Jansen went completely belly-up in the 10th -- the Giants scoring three times for a 7-4 victory Sunday afternoon. And pigs can fly.

The Giants took three of four games in this series and are 7-3 against the Dodgers this season, leading them by 4 1/2 games in the National League West.

It wasn’t supposed to work out that way Sunday after the Dodgers had rallied to take a 2-1 lead with a pair of runs in the sixth inning on a Yasiel Puig solo homer and a run-scoring single by Adrian Gonzalez.

It was Kershaw’s second start since coming off the disabled list Tuesday after a sore shoulder kept him sidelined since late April, but he seemed to be dealing, as usual.

But then Pablo Sandoval led off the seventh inning with a single to bring up Hicks. Kershaw had struck out Hicks in each of his first two at-bats and quickly got ahead of him 0-2. The script seemed written, until it wasn’t.

Hicks crushed a Kershaw curveball, sending it deep into the Dodgers bullpen.

After a rough first inning, when he gave up a run on three hits, Kershaw had been in control the rest of the afternoon. He ended up going seven innings, giving up three runs on seven hits. He did not walk a batter and struck out nine.

It would have been a vintage Kershaw outing, save for that one swing by Hicks.

The Giants added a seeming insurance run in the eighth inning off Chris Withrow on a Buster Posey single, and then Giants closer Sergio Romo was one out from ending it. But with Dee Gordon on second base after a double, Ramirez lined his home run to left to send the game into extra innings.

But Jansen allowed five of the first six batters he faced to reach base and mixed in a run-scoring wild pitch, leaving the Dodgers 3-7 in extra innings this season.

The Dodgers managed 14 hits, but went three for 14 with runners in scoring position.

Andre Ethier returned to the lineup and reached base four times with two doubles, a single and a walk. Puig’s sixth home run extended his hitting streak to 11 games.
