One of the offseason's most disappointing acquisitions will try to influence the race in the National League West when the Arizona Diamondbacks face the Los Angeles Dodgers on Tuesday night at Dodger Stadium. Right-hander Shelby Miller, whom the Diamondbacks acquired in a five-player trade from the Atlanta Braves in December, seeks to end a four-game losing streak against the team that leads the second-place San Francisco Giants by four games. In eight starts at Reno, Miller went 5-1 with a shutout and 55 strikeouts in 50 2/3 innings.
