Max Muncy homered and scored twice, and Kenta Maeda pitched seven scoreless innings for his first victory in more than two months as the host Los Angeles Dodgers blanked the Arizona Diamondbacks 4-0 on Saturday. Russell Martin had two hits and an RBI, and Kris Negron had an RBI single for the Dodgers, who have won nine of 11 and will attempt to win their fifth consecutive series in the final game of the three-game set Sunday. Maeda (8-8) gave up three singles and struck out six without a walk.
