Diamondbacks 2, Rockies 1: Carroll Walks Off as Rodriguez Shuts Out Colorado for Seven

The lead

May 21, 2026 - Phoenix - The Arizona Diamondbacks won their fifth straight and ninth in 12 with a 2-1 walk-off over the Colorado Rockies at Chase Field, as Eduardo Rodriguez worked seven scoreless innings on four hits and Corbin Carroll lined the winning single in the ninth, per The Arizona Republic and MLB.com's game story.

Manager Torey Lovullo called it a "chewing-on-rocks type of a win"—Rodriguez bounced back after failing to escape the sixth inning at Coors five days earlier. Gabriel Moreno's gritty walk set up the ninth before Jose Fernandez sacrificed him to second and Ketel Marte walked ahead of Carroll's base hit through the right side—Carroll's fourth career walk-off and first since 2024.

How the game turned

Colorado tied it 1-1 in the eighth before Arizona answered in the ninth. Rodriguez induced 10 groundouts and threw 63 of 99 pitches for strikes, per Purple Row's game coverage. Carroll ended it with one swing—no extras required.

Rookie Zach Agnos matched Rodriguez into the middle frames for Colorado before the bullpen took over.

Pitching and matchup notes

Rodriguez (4-1) logged the fourth time in 10 starts he has reached seven innings—something he did only twice in 39 starts across his first two Diamondbacks seasons, the Republic noted.

AthX Engine graded Rodriguez at 22 pitching FP and Arizona at 6 team FP on the seven-game Thursday card.

Bats that changed the board

Moreno's plate discipline and Carroll's clutch swing turned a pitcher's duel into a sweep-opening walk-off—Arizona's fifth consecutive home win.

AthX Engine fantasy angle

22 pitching FP from a seven-inning shutout can outscore a 6 team FP night when the offense waits until the ninth—AthX Engine captures Rodriguez's value even in low-run finals, separate from dynamic pricing.

What comes next

Arizona continues hosting Colorado; the Rockies seek run support after another tight loss in the desert.
