Clayton Kershaw (13-4, 2.68) vs. Ian Kennedy (13-3, 3.17).
The Giants, in first place, have lost three in a row. The Diamondbacks, a mere half-game out of first place, have also lost three in a row. The Dodgers are in position for a rare sweep. And everybody's starting their aces today: Kershaw against Kennedy in Arizona, while Tim Lincecum takes on the Phillies' Roy Oswalt. The Dodgers may not be able to play quality baseball, but win or lose, they can play the spoiler.
