David Peralta's bases-loaded, two-run single against his former team broke a scoreless tie in the eighth inning and the Los Angeles Dodgers beat the Arizona Diamondbacks 2-0 on Wednesday night. The win was the fourth in a row for Los Angeles while Arizona has lost eight straight. The loss dropped them under .500 for the first time since they lost the home opener to the Dodgers on April 6 to go 3-4.
