Corbin Carroll is on pace for a career season through 46 games, and he just added his first walk-off hit of the season for the Arizona Diamondbacks.The All-Star outfielder walked off the Colorado Rockies to give the D-backs their fifth straight win, and their second in three games after Starling Martes homer against the San Francisco Giants on Tuesday.With the game tied 1-1 and two outs, Rockies reliever Juan Mejia left a 2-2 sweeper in the middle of the zone. It proved easy work for Carroll to score Gabriel Moreno from second base. Final score: 2-1 D-backs.THAT'S OUR CATCHER pic.twitter.com/DFfVbVP4YY Arizona Diamondbacks (@Dbacks) May 22, 2026Carroll knocked in both of Arizonas runs, putting them on the board with a groundout in a sixth-inning rally. The Rockies tied the game when D-backs reliever Juan Morillo hit Tyler Freeman in a bases-loaded jam, but Kevin Ginkel entered the game and ended the threat.All of that made sure Eduard Rodriguezs start of seven scoreless innings wasnt for naught.After going 1-for-5 on Thursday, Carroll is now slashing .282/.390/.552and leads MLB with six triples.After a rough stretch in late April and early May, the D-backs winning streak has pushed their record 26-23, good for a comfortable third place in the NL West. They are 4.5 games back from the first-place Los Angeles Dodgers and two games back from the St. Louis Cardinals for the NLs final wild-card spot.
