Chad Billingsley (4-8, 4.20) vs. Trevor Cahill (6-7, 3.63).
Tonight is part 1 in the Diamondbacks' Attack of the Trevors, with Cahill having hitched his waggons to the Snakes after three years of service with the A's (40-35, 1 All-Star appearance). Cahill has one career appearance against the Dodgers, going six innings without a decision.
As for Chad Billingsley? We need a win tonight, Bills, to ensure we'll remain in first place (irrespective of the Giants' fate). Can you Stave (off) Trevor? All the world is waiting for you, and the powers you possess.
