The Arizona Diamondbacks have sent a message to the Los Angeles Dodgers in the first two games of their NL West showdown: This is going to be a three-team race after all. Paul Goldschmidt homered in the first inning for the second straight game, Miguel Montero added a three-run shot and rookie Wade Miley pitched eight dominant innings for the Diamondbacks in an 8-2 victory over the Dodgers on Tuesday night.
