Arizona and Colorado are involved in a big series. The pitching matchup for Tuesday is Zach Greinke versus Antonio Senzatela. I want Greinke going for me.

The Diamondbacks are 7-2 in Greinke's last nine road starts. I regard Greinke at least two levels higher than Senzatela, who has close to a 5.00 ERA and owns a horrible history versus the Diamondbacks with a lifetime 8.27 ERA in six career games. He is 0-2 with a 6.75 ERA in two games, including one start, against Arizona this season.

Greinke is coming off a rare bad start. A bad start for Greinke is giving up four earned runs. Only twice in his last 15 starts as he allowed more than three earned runs. Greinke is 2-0 with a 2.33 ERA in three starts versus Colorado this season.

The Diamondbacks have fared well at Coors Field, too, winning nine of their last 12 there.
