The Diamondbacks Can Win If…
The Arizona Diamondbacks are coming off a strong win against the Toronto Blue Jays, 9-5. Ryne Nelson pitched well, allowing just one hit and one run over 5 2/3 innings. Eugenio Suárez led the offense with a home run and four RBIs, while Pavin Smith also hit a home run, contributing three RBIs.
The Diamondbacks have been solid at the plate this season. They rank 3rd in slugging percentage at .442 and 4th in home runs with 104. Their ability to hit for power gives them an edge in any game, and they have shown they can score runs in bunches.
Arizona’s lineup features several key players who can make a difference. Josh Naylor is hitting .304 with 49 RBIs, and Ketel Marte boasts a .289 average with 12 home runs. With Zac Gallen starting on the mound, the Diamondbacks have a chance to secure another win against the Colorado Rockies.
The Rockies Can Win If…
The Colorado Rockies are coming off a close 4-3 loss to the Washington Nationals. Despite the loss, the Rockies tallied 11 hits, showing their ability to get on base. Key players like Jordan Beck and Ryan McMahon contributed with hits, keeping the game competitive.
The Rockies have shown they can hit for power, ranking 17th in home runs this season with 73. Their lineup features Hunter Goodman, who leads the team with 14 home runs and 46 RBIs. With a mix of power and timely hitting, the Rockies have the tools to put runs on the board.
Pitching will be crucial, and Austin Gomber is set to start with an impressive ERA of 0.00. In his last outing against the Braves, Gomber pitched five innings without giving up a run. If he can maintain this form, the Rockies have a strong chance to secure a win against the Diamondbacks.
The Lean
The Diamondbacks are favored with a MoneyLine of -191 against the Rockies at +158. The Diamondbacks have a stronger batting lineup, ranking 3rd in slugging percentage and 4th in home runs. The Rockies struggle with a 29th-ranked ERA. My model projects the Diamondbacks to win with a score of 7-5.
The over/under line is set at 11.5. The Diamondbacks’ strong offense and the Rockies’ pitching struggles suggest a high-scoring game. My model projects a total score of 12, so the recommendation is to take the over.

D-backs, Rockies Riding High Entering Weekend Series in Denver
The Arizona Diamondbacks and Colorado Rockies are both heading into their weekend series in Denver feeling good — but for very different reasons.
Arizona snapped a five-game road skid with a solid 9-5 win in Toronto on Thursday. Meanwhile, Colorado returns to Coors Field after going 4-3 on its latest road trip, including a four-game winning streak before an extra-inning loss in Washington.
Both clubs aim to keep that momentum rolling when the series opens Friday night. Zac Gallen (4-8, 5.19 ERA) takes the mound for Arizona against Rockies lefty Austin Gomber (0-0, 0.00 ERA), who is making just his second start since returning from a shoulder injury.

Rockies Building Confidence
The Rockies’ recent run — 8-8 over their past 16 — has helped pause concerns about a historically bad season. Though still on pace to challenge the modern era loss record (121 by last year’s White Sox), Colorado has shown signs of life, especially on the road, where they are 7-3 since June 2.
“Boys are playing hard, boys are playing good,” Rockies interim manager Warren Schaeffer said. “They’re paying attention to details; they’re playing with energy. It’s just good stuff, fun to be a part of.”
Now, the challenge is translating that effort to Coors Field, where they’ve dropped 11 of their last 13.
Pitching Matchup
Gomber looked sharp in his season debut Sunday, tossing five scoreless innings in Atlanta. He’s 3-1 with a 5.65 ERA in 14 career appearances against Arizona.
Gallen has a strong history vs. Colorado, going 7-1 with a 3.03 ERA. He’s been especially good in Denver, sporting a 2.79 ERA in seven starts at Coors Field. Friday will mark his 17th career outing against the Rockies, the most of any opponent in his career.
D-backs Updates
Stay Ahead With Proven MLB Betting Strategies and Expert Tips
Arizona will be without catcher Gabriel Moreno, who was placed on the 10-day IL with a right hand contusion after trying to play through the injury.
“Very unfortunate for Gabby,” D-backs manager Torey Lovullo said. “He was doing his best to manage it. Sometimes things don’t heal the way you expect.”
The D-backs did get a boost when X-rays on Corbin Carroll’s left hand showed no fracture after he was hit by a pitch Wednesday. Carroll sat out Thursday but could return for the Colorado series.
