First pitch 3:10 p.m. ET
Venue: Coors Field, Denver, Colorado
This is the series finale. The Diamondbacks have won the first two games of the set (including a 5-3 victory on Wednesday) and are on a four-game winning streak overall. Arizona is fighting for an NL wild-card berth, sitting a few games behind the Phillies and Cubs with limited games remaining. The Rockies are mired in a dreadful season (one of the worst records in baseball) and have lost heavily of late (including 14 of 16 in one stretch).
Starting Pitchers
Diamondbacks: LHP Eduardo Rodriguez (15-7, 2.89 ERA, 1.23 WHIP, 140 K in 183.2 IP over 31 starts). The veteran lefty has been one of the more reliable starters in the NL this season with strong run prevention. He has a solid track record in limited previous work against Colorado.
Rockies: RHP Tanner Gordon (1-5, 6.01 ERA, 1.55 WHIP, 84 K in 100.1 IP over 11 starts/23 appearances). The right-hander has struggled significantly, especially at Coors, allowing high hit and run totals in recent outings (e.g., shelled for 7 runs in 3 IP vs. San Diego recently).
Rodriguez holds a massive edge in every major category. Coors Field amplifies offense, but the quality gap in starting pitching is substantial.
Current Weather Forecast (Coors Field)
Mostly cloudy with a chance of showers (around 30-40% precipitation chance), highs near 70-74°F. Northeast winds 10-15 mph possible in the afternoon. Cooler conditions for Denver with potential light rain or storms. The thin air and any wind can still favor hitters, but cooler temps may slightly suppress extreme scoring compared to typical hot Coors days.
Injury Reports
Diamondbacks:
Ryan Thompson (RP, back) – 60-day IL.
Tyler Locklear (1B, thumb) – 60-day IL.
Andrew Saalfrank (RP, shoulder) – 60-day IL.

Key Player vs. Player Matchups / Notable Performers
Gabriel Moreno (D-backs, .310 AVG) – Contending for the NL batting title; multi-hit force recently.
Corbin Carroll (D-backs) – Speed and power threat (recent two-run triple); elite baserunner.
Nolan Arenado / Ketel Marte – Arenado provides power (28 HR) and RBI production; Marte sets the table.
Hunter Goodman (Rockies, 39 HR) – Primary power source for Colorado.
TJ Rumfield / Jake McCarthy / Ezequiel Tovar – Rumfield hitting near .296; McCarthy productive; Tovar has shown pop (recent HR).
Rodriguez (lefty) vs. Rockies right-heavy lineup and Gordon vs. Arizona’s mix of contact and power hitters.
Coors Field historically inflates offense, so even modest contact can turn into extra-base hits.
Recent Team Forms
Diamondbacks: W4 streak; 5-5 in last 10 overall but surging with playoff urgency. Road record near .500 (39-38). Offense productive with timely hitting.
Rockies: L3 (and much worse in broader stretches, e.g., 2-8 in last 10). Home record poor (32-48). Pitching has been a major liability all year.
Series History (2026)
Diamondbacks lead the current three-game set 2-0 and are going for the sweep. Arizona has dominated recent meetings against the struggling Rockies. Season series heavily favors the D-backs.
Betting Trends
Heavy public and sharp money on Arizona due to the pitching mismatch and form. Overs are common at Coors, though cooler weather and Rodriguez’s quality could temper extreme scores. Rockies as big underdogs at home with a poor record.
Game Odds
Arizona Diamondbacks – 179
