The Rockies currently have the 15th best starter’s ERA in baseball at 4.56 and considering where they have been over the past handful of seasons, they have been a huge surprise this year.
Their ace, Jon Gray, hasn’t played since early on in the season due to injury so when he returns, he will add to the youngsters that have carried them this far.
Antonio Senzatala and Kyle Freeland are both candidates for Rookie of the Year and have been the backbone of this team. Tyler Chatwood and Tyler Anderson have been wildly inconsistent to start the season, but they can hold their own until the bullpen arrives. More on that later.
Considering half the games this team plays is at Coors, they have been doing just fine. Like I said when Jon Gray returns they will get even stronger. Who knows, they might even acquire a big arm at the deadline.
The Diamondbacks aren’t impressed though as they have the best starting rotation with a 3.45 ERA.
Old friend Zack Greinke has been leading the way with his resurgent season as he currently owns a 3.14 ERA and has brought his name up into Cy Young conversations again. As good as Greinke has been, his teammate Robbie Ray has been one-upping him as he owns a 2.87 ERA and has been the team’s best starter.
Taijuan Walker is looking like a formidable option after coming over from the Mariners and has been able to keep his ERA under four. Patrick Corbin and a combination of spot starters have rounded out Arizona’s rotation. They have not been as successful as the first three guys, but they are aided by a great offense and bullpen.
The Diamondbacks have the best rotation in baseball, statistically, which is no slight to Colorado, and Ray plus Greinke put the D-backs on another level.
Advantage: Arizona Diamondbacks
