"If Clayton Kershaw continues to pitch the way he's pitched, who knows how many games he can win? And if Matt Kemp continues to run the way he's run, who knows how many bases he can steal?

On a night that started with the Dodgers and San Francisco Giants taking the field in a pregame ceremony to remind fans at AT&T Park that they shouldn't attack each other, the chants of "Beat-L.-A." that followed were soon muted by Kershaw's arm and Kemp's legs.

But the promise offered by Kershaw and Kemp's performances in the Dodgers' 6-1 victory over the defending World Series champions was tempered by a sobering reality on the far end of the clubhouse: Rafael Furcal was hurt again.

Furcal, who has battled back problems in recent years, broke his left thumb on a head-first slide into third base in the fifth inning. The 33-year-old shortstop was so crestfallen that he started talking about the possibility of retirement.

"Every time I feel good . . ." Furcal said. "I felt good with my back. Now my finger? What do you think I'm thinking?"

Furcal said he would return to Los Angeles to be reevaluated. Injuries similar to his typically take four to six weeks to heal.

Manager Don Mattingly, who either didn't know about the results of Furcal's X-ray exam or was hiding them, spent his postgame session with reporters marveling at what Kershaw and Kemp did.

Kershaw (2-1) held the Giants to six hits and two walks over 62/3 scoreless innings. Kemp stole his seventh base on his way to scoring his team-leading eighth run, as the Dodgers improved to 6-4 while dropping the Giants to 4-6. The Dodgers are 4-1 against San Francisco this season."
