Colorado Rockies vs. Arizona Diamondbacks game discussion: Merrill Kelly vs. Mason Adams

Promising rookie Mason Adams gets his sixth start, bringing in an 0-1 record, a 5.09 ERA, and 23 strikeouts to 12 walks. His last three starts have been a bit of a rollercoaster in terms of traffic on the basepaths, as Adams gave up eight, two, and then eight hits in those respective starts. He's also surrendered at least one home run in each of his six starts. Adams' last outing was the worst of his young career, with six runs allowed on eight hits with only one strikeout to three walks in a 9-3 loss to the San Diego Padres .

The Diamondbacks try to slither up the Wild Card standings, currently sitting four games behind the Chicago Cubs , Philadelphia Phillies , and Padres. The Phillies found a win last night, while the Cubs and Padres both lost, knotting all three clubs at 87-70.

Arizona will roll out Merrill Kelly , currently 9-14 through 28 starts and a 5.00 ERA. This will be Kelly's third time facing Colorado in 2026, picking up a win in a 9-1 victory back in May and a loss in a 6-4 game in August. Kelly is on the same rollercoaster as Adams, giving up seven, two, and seven hits in his last three games. The back end of the season has been difficult for Kelly, who took losses in five of his last seven starts.
