The Colorado Rockies’ season hit rock bottom on Tuesday night. With their 100th loss, they became the first franchise to suffer a 100 or more defeats in four consecutive seasons since the 1962-65 New York Mets. The organization has dropped eight of its last 10 games, and as general manager Josh Byrnes noted recently, losing 100 games again is simply not good enough. They are struggling to find any sustained traction to end the year, and the slide looks difficult to stop.
Arizona enters this matchup with an entirely different set of stakes. They sit four games back in the National League wild-card race with only five games remaining, making every inning a desperate push for the postseason. The Diamondbacks are an even 10-10 over their last 20 games and 5-5 over their last 10. They have essentially been treading water, but their bats looked plenty sharp in their 7-2 win over Colorado yesterday. They consistently cashed in on run-scoring opportunities, proving they can reliably take advantage of favorable pitching matchups.
To keep this one competitive, Colorado needs to find an offensive pulse early. First pitch is set for 6:40 p.m. MT, and the Rockies’ only realistic path tonight relies on giving their rookie starter some immediate run support.
The Breakdown
Tonight’s pitching matchup features rookie Mason Adams squaring off against veteran Merrill Kelly. Acquired by Colorado in early August, Adams has had a tough time pitching deep into games lately. Across his last five starts (23.0 innings pitched), he is averaging just 4.60 innings per outing with a 5.09 ERA. The core issue is his command. Adams is handing out 4.70 walks per nine innings during that stretch, putting constant pressure on himself and forcing an overworked Colorado bullpen into action far too early.
On the other side, Kelly has shown some vulnerability over his last 10 starts. While he manages to eat some innings – averaging 5.30 frames per outing – he is also battling his control. Across his last 53.0 innings of work, Kelly has walked 4.75 batters per nine innings while carrying a 4.76 ERA and a 1.47 WHIP.
The deciding factor tonight will be whether the Rockies can match the power of an Arizona lineup that has been flexing its muscle. Over their last 10 games, the Diamondbacks have blasted 15 home runs and averaged 5.20 runs per game, posting a robust .819 OPS. Meanwhile, Colorado’s offense has generated far less punch, hitting just nine homers and averaging 4.10 runs per game over their own 10-game stretch.
For the Rockies to pull out a victory, Adams must find the strike zone early, pitch efficiently, and push into the later innings. Offensively, Colorado has to exploit Kelly’s recent tendency to issue walks. If the lineup can work deep counts, create traffic on the basepaths, and capitalize with runners in scoring position, they have a genuine chance to outscore a dangerous Diamondbacks squad.
Odds & Lines
- Moneyline: Arizona Diamondbacks -159 | Colorado Rockies +134
- Run Line: Arizona Diamondbacks -1.5 (-104) | Colorado Rockies +1.5 (-115)
- Over/Under: 11.5 (Over +103 / Under -125)
Our Pick
Let’s be blunt: the Rockies are outmatched tonight. Colorado has dropped eight of its last 10 games, offering very little resistance in the late innings where their bullpen continues to bleed runs to the tune of a 4.84 ERA. The Diamondbacks possess the clear advantage when it comes to exploiting Colorado’s pitching weaknesses, and they have every incentive to win as they chase a playoff berth.
Caesars is showing the Diamondbacks on the run line at -1.5 (-104), which offers far better value than laying the heavy juice on the moneyline. If you are backing Arizona tonight, make sure to grab the Caesars promo available for new users. Arizona’s bats looked dominant in their previous matchup against this Colorado staff. With the Rockies struggling to string together consistent offensive innings, asking the Diamondbacks to win by at least two runs is a highly logical expectation.

Player Prop Pick
When evaluating tonight’s matchup, it is impossible to ignore Ezequiel Tovar’s track record against Arizona starter Merrill Kelly. The Rockies’ shortstop has thoroughly dominated the veteran right-hander throughout his career. In 18 plate appearances against Kelly, Tovar has racked up eight hits – including three doubles and a pair of home runs. That translates to a staggering .444 batting average and a .944 slugging percentage in this specific head-to-head battle.
Tovar has also been swinging a steady bat recently, posting a .269 average and a .423 slugging percentage over his last 10 games while scoring eight runs. Although Kelly has generally been tougher on right-handed batters this season, Tovar consistently proves to be the exception to that rule. Finding a significant edge for Colorado can be tough given their current slide, but this matchup history is too pronounced to pass up.
DraftKings has Tovar’s total bases line set at 1.5 with enticing +161 odds on the over. Check out the theScore Bet promo if you want to explore more lines. Given his extreme comfort level against Kelly and solid recent form, backing the Colorado infielder to produce tonight is a high-value play.
