Yes, the Colorado Rockies are pitching better at home than on the road

Drastic home and away splits are nothing new for the Colorado Rockies. But thus far, an underwhelming 2021 season has presented some truly head-scratching results for Rockies’ pitchers. They are pitching better at Coors Field than they are away from Coors. Much, much better, in fact.

There are some shocking numbers when it comes to the Colorado Rockies pitching at Coors Field.

As a team, their home ERA of 4.56 is more than a run lower than their road ERA of 5.58. That is unusual considering the Rockies play in what is widely recognized as one of — if not the —greatest hitters’ park in the game.

But those numbers include the bullpen. If you look at only the starters’ ERA, the gap grows considerably. At home, the Rockies actually have one of the better starting staffs in baseball. Their 3.40 home ERA is ninth in all of baseball. However, on the road, their starters drop to 29th with a 6.30 ERA. That is a difference of almost three runs.

Nearly every arm in the rotation has been affected by this unusual split. Staff ace Jon Gray has a 2.00 ERA at home but a 6.89 on the road. Chi Chi Gonzalez has a 2.12 ERA at home and a 6.20 on the road. Austin Gomber has a 1.88 ERA at home and a 6.39 on the road. Antonio Senzatela has a 4.46 ERA at home and an 8.59 ERA on the road. Only German Marquez has a better road ERA (4.60 versus 4.91).

The Rockies bullpen has been better on the road (4.50) than at home (6.35), but both splits are bad. In contrast, what’s so striking about the starters’ splits is that they are actually very good at home but somehow very bad on the road. The fact that those great home numbers are coming at Coors Field only adds to the peculiarity of this split.
