I like the Arizona Diamondbacks in this matchup on Saturday night.

Zach Greinke would have started on Opening Day, but he suffered a groin injury on March 14th, which set him back a bit. Greinke bounced back from a disappointing 2016 season to go 17-7 with a 3.20 ERA in 32 starts last year. He always pitches well at home and this is a good spot for him.

For the Rockies German Marquez has really struggled in spring training games. In four starts he struggled with a 9.82 ERA while trying to figure out his changeup.
Arizona should be able to take care of business in this one.
