D-backs buzz by Dodgers in 10th inning

Christian Walker hit two home runs, including a game-ending two-run shot in the 10th inning, as the Arizona Diamondbacks stung the Los Angeles Dodgers by picking up a 4-3 victory in Phoenix on Tuesday. Six Arizona pitchers held the Dodgers to zero RBIs through nine innings as the Diamondbacks won for just the second time in their past six games. Will Smith gave the Dodgers a brief lead with a sacrifice fly in the 10th inning after Los Angeles scored its first two runs on a wild pitch and a balk. Rookie Landon Knack gave up one run on four hits over five-plus innings for the Dodgers.
