Thursday, June 23rd 6:40pm: Zack Greinke (10-3 3.54 ERA) vs. Eddie Butler (2-4 6.26 ERA)
Greinke has regained his form as an ace pitcher since his terrible start, but coming to Coors Field is never a pitchers dream. Greinke hasn’t faced the Rockies since April 30th and both starts against Colorado this year have been at home for Greinke. The Rockies will look to replicate the season opener in which they scored seven runs in four innings against Greinke. They will almost certainly need the offense to show up with Eddie Butler on the mound. Butler has shown why he has been a disappointment for the Rockies in his last four outings. He has allowed 21 runs in 18.1 innings over those four outings and is in need of getting back on track. He has not faced Arizona yet this year so hopefully a new opponent gets him some confidence back.
Friday, June 24th 6:40pm: Archie Bradley (3-3 4.83 ERA) vs. Tyler Anderson (0-1 2.25 ERA)
Tyler Anderson has been a blessing for the Rockies as their rotation has been inconsistent at best. Anderson has been solid in both of his starts this year but is still looking for his first big league win. Bradley is another young pitcher and he has pitched much better on the road this year. However, he did make a start against the Rockies at Coors Field and did allow four runs over six innings. The Rockies would like to get more offense than that, but scoring four runs gives Anderson a shot at a win.
Saturday, June 25th 2:10pm: Shelby Miller (2-6 6.36 ERA) vs. Jorge De La Rosa (4-4 7.17 ERA)
Shelby Miller, unlike Greinke, has not regained his form and has allowed at least one run every start this year, while allowing three or more runs in seven of ten starts. The Rockies have done well against Miller in both of his starts this year and those were both at home for Miller. A change of scenery may lead to different results, but Coors Field is no more a pitcher friendly park than Chase Field. Jorge De La Rosa and the Diamondbacks have a lot of history and De La has not been that great against Arizona. De La hasn’t been that great in general this year, but has been much better since being moved to the bullpen and coming back to the rotation. De La is the winningest pitcher in Rockies history and there is a reason for that, but going forward De La needs to keep up his solid outings or risk being traded or something worse.
Sunday, June 26th 2:10pm: Patrick Corbin (4-6 4.63 ERA) vs. TBD
The Rockies have not yet announced their starter for this game and they could make a move to bring someone up to fill the rotation spot. Gray wouldn’t pitch without full rest, especially after leaving with arm fatigue and Jordan Lyles as the long man is not the starter the Rockies want to be stuck with. With Rusin, Chatwood, and Bergman on the DL, the Rockies may bring up one of their young guns Jeff Hoffman or Kyle Freeland. The fact of the matter is the rotation is struggling right now and whether the Rockies compete going through the year relies almost entirely on the rotation exceeding expectations.
