Coors Field, Denver, Colorado
First pitch: 8:40 p.m. ET (6:40 p.m. MT)
TV: Rockies.TV / Dbacks.TV
The Diamondbacks are fighting to keep their slim playoff hopes alive (elimination number recently at two) with a three-game winning streak. The Rockies have already reached 100 losses and rank near the bottom of MLB. This is Game 2 of a three-game series; Arizona won the opener 7-2 on Tuesday. The Diamondbacks lead the season series 7-4.
Probable Pitchers
Diamondbacks: RHP Merrill Kelly (9-14, 5.00 ERA, 1.47 WHIP, 111 K). The veteran has been up-and-down but has shown better results in recent starts (three or fewer earned runs in his last five). He faces a struggling Rockies offense at Coors.
Rockies: RHP Mason Adams (0-1, 5.09 ERA, 1.65 WHIP, 23 K in limited action). The young right-hander is making one of his early big-league starts (around his sixth appearance). High WHIP and limited experience make him a high-risk option at Coors Field.
Current Weather Forecast
Mostly cloudy with a chance of showers/thunderstorms possible (around 15–40% in some forecasts). Temperatures in the upper 60s to low 70s°F around first pitch (highs near 70–80°F earlier), light winds (around 6–10 mph, variable directions, sometimes out to right field), moderate humidity. Typical Coors conditions that can inflate offense.

Key Rosters / Notable Players
Diamondbacks: C Gabriel Moreno (.306 AVG, strong recent form), 3B Nolan Arenado (28 HR, consistent producer), OF Corbin Carroll (power/speed), INF Ketel Marte, SS Geraldo Perdomo, and a balanced lineup.
Rockies: C/1B Hunter Goodman (39 HR, team leader in power), 1B TJ Rumfield (.300 range), OF Jake McCarthy (RBI leader), and younger contributors filling gaps. Offense has shown some life at home but overall ranks poorly in advanced metrics.
Key Player vs. Player Matchups
Both right-handers face lineups with power potential. Kelly must navigate Coors’ thin air against Goodman’s power and Rumfield’s contact.
Adams faces a more experienced Diamondbacks group featuring Arenado’s experience and Moreno’s hot bat.
Coors Field historically favors hitters heavily, especially with any wind blowing out.
Recent Team Forms
Diamondbacks: Solid (winning streak of three, roughly 5-5 in last 10). Road record even at 38-38. Motivated for every remaining win.
Rockies: Poor (2-8 in last 10, outscored significantly, high ERA). Home record 32-47. Already mathematically eliminated and playing for development.
Series History
12th meeting of 2026 (Diamondbacks lead 7-4; lead current series 1-0 after 7-2 win). Arizona has dominated recent matchups, including multiple multi-run victories.
Betting Trends
Trends strongly favor Arizona given the season series edge, superior record, and Rockies’ collapse. High totals are standard at Coors; recent series opener stayed relatively contained but still produced runs.
Game Odds
Arizona Diamondbacks – 150
Colorado Rockies 11
