The Arizona Diamondbacks' biggest offseason acquisition is set to make his first appearance against the team he represented for three seasons and helped win three successive division championships. Right-hander Zack Greinke, who spurned the Los Angeles Dodgers as a free agent to sign a six-year contract worth $206.5 million, will pitch against his former teammates Monday evening when the Diamondbacks begin a three-game series at Dodger Stadium. From 2013 through 2015 with the Dodgers, Greinke won 51 games and compiled a 2.30 ERA.
