Arenado's grand slam powers D-backs 9-0 rout

Nolan Arenado hit a first-inning grand slam against his former Colorado Rockies as the Arizona Diamondbacks rolled to a 9-0 victory at Chase Field. The win moved Arizona to eight games above .500 and helped cement their grip on the NL wild-card race, aided by Michael Soroka’s return from a injury layoff. Zack Littell earned the win in relief, delivering 4 2/3 innings of two-hit, two-walk relief in his D-backs debut. Arenado’s slam—his eighth career and second of the season—helped push Arizona ahead 4-0 early, with contributions from Corbin Carroll, Ketel Marte, and Geraldo Perdomo. The Rockies were held scoreless for the sixth time this year, while Arizona benefited from timely hits and extended their strong late-season surge. Colorado has dropped six of its last seven games, as Arizona rides a 19-9 run since July and tightens its postseason position.
