Kershaw strikes again in close game

SAN FRANCISCO — Clayton Kershaw struck out seven over seven innings in another impressive performance in San Francisco’s home ballpark, and the Los Angeles Dodgers beat the Giants 2-1 Tuesday night to end a four-game losing streak against their rival.

Buster Posey extended his hitting streak to 11 games with an RBI single in the third that put the Giants ahead, but then Yasiel Puig singled in a run in the fourth and Adrian Gonzalez’s groundout drove in another.

The Dodgers, who were on the other end of a 2-1 result a night earlier, also ended a sixgame skid at AT&T Park to avoid matching the franchise’s longest winless stretch in San Francisco from April 21-Sept. 28, 2015.

Lefty Ty Blach (0-1) allowed two runs and four hits in five innings making his first start in place of injured Madison Bumgarner. The ace southpaw bruised his ribs and sprained the AC joint in his pitching shoulder in a dirt bike accident last Thursday during a day off in Colorado.

Brandon Crawford grabbed his right groin immediately after rounding first when he followed Posey’s two-out single in the eighth with a base hit off Kenley Jansen. The shortstop was looked at by athletic trainer Dave Groeschner then came out of the game.

Pinch-hitter Brandon Belt then struck out to strand Posey on third as the tying run.

In the ninth, Cody Bellinger beat out an infield single in his major league debut after being called up by the Dodgers to start in left field. A day after San Francisco promoted top prospect Christian Arroyo to play third base, the Dodgers brought up their top prospect from the same 2013 draft class.

Arroyo also got his first major league hit — and a lengthy standing ovation — on a single in the first after going 0 for 4 with three groundouts and a strikeout in his debut a day earlier after being called up from Triple-A Sacramento.

Kershaw (4-1) allowed six hits

and one run, walking one as he improved to 11-4 in 19 outings and 18 starts in San Francisco’s waterfront ballpark. Jansen finished for his fifth save and the 15th of his career recording four outs.

Justin Turner matched his career-best hitting streak at 11 games with a first-inning single.

Trainer’s room — Giants: An MRI exam on Matt Cain’s tight right hamstring that he felt during his win Monday showed no problems and he is slated to take his next turn in the rotation.
