Christian Walker extended his tear at Dodger Stadium on Thursday night, homering in his first two at-bats for his 18th and 19th home runs in 42 career games at the ballpark, and the Arizona Diamondbacks beat the Los Angeles Dodgers 9-3. Joc Pederson drew boos from the sellout crowd of 52,320 when he went deep against his old team in the first, just before Walker blasted a 435-foot shot to center field off rookie Landon Knack (1-2) with two outs. Walker had two strikes in the third when he hammered a two-run shot to left with two outs, extending Arizona's lead to 4-0.
