Diamondbacks to play the Rockies for Rivalry Week in 2025

The Diamondbacks and Rockies have both played in the National League West since the 1998 season. Arizona has won 15 of the 27 season series between the two teams, including the last two seasons, with a 257-203 overall record. They’ve met up twice in the postseason, with the Rockies sweeping the 2007 National League Championship Series and the Diamondbacks winning the 2017 National League Wild Card game 11-8.

Part of the reason for this rivalry comes down to geography. While Denver and Phoenix aren’t the closest MLB cities to each other, being in the same division with some postseason history between the two clubs certainly doesn’t hurt. The two organizations also share the same complex at Salt River Fields at Talking Stick.

It will be interesting to see how this works out in the scheduling. With the current schedule, all 30 teams play each other every year. In the case of the Diamondbacks and Rockies, they play each other 13 times a year due to being in the same division. As a result of that, I don’t think slapping a “Rivalry Week” label to that series makes it any more or less important between the two teams.
