Here’s the Rockies’ Spring Breakout roster (Sat., 5:30 p.m. MDT)

Rockies and Diamondbacks prospects walk the path to the Majors together. They share Salt River Fields at Talking Stick, meaning from the moment they turn pro, they are more likely to oppose each other in games on the backfields. They oppose each other at most Minor League stops and even play together in the Arizona Fall League. The Spring Breakout is a time for both prospects to shine before a broader audience.

What is Spring Breakout?

In 2026, MLB Spring Breakout will again be a four-day event showcasing baseball’s future -- the current stars of Minor League Baseball – in 16 exhibition games played between teams composed of each MLB organization’s top prospects. The third edition will be held from March 19-22 at Grapefruit and Cactus League stadiums during Spring Training.

In 2027, Spring Breakout will be expanded into a single-elimination tournament format, with champions being crowned in both the Grapefruit and Cactus leagues.

When is the Rockies' game?

Saturday, March 21, 5:30 p.m. MDT. The Rockies' Spring Breakout game will begin exactly 30 minutes after the conclusion of the D-backs' MLB Cactus League game, which begins at 2:10 p.m. MDT.
