The Colorado Rockies will welcome the Miami Marlins to Coors Field on September 18, 2025, with the familiar aim of using their home field advantage to offset another difficult campaign, as they sit at 59-93 and entrenched at the bottom of the National League standings, but still dangerous on any given night thanks to the unique environment of Denver and the unpredictability of their young roster. Colorado will send Tanner Gordon to the mound, a right-hander who has endured a rough season with an ERA well above six and a high walk rate that has too often put him in early trouble, a concerning trend in a hitter’s park where base runners typically turn into runs quickly. The Rockies’ lineup, however, continues to show flashes of promise, led by Nolan Jones, who has emerged as the team’s most productive bat, capable of supplying both power and consistency, while Brenton Doyle adds defensive excellence in the outfield and speed on the bases, and Elehuris Montero has chipped in with spurts of power that can alter games at Coors. Colorado’s bullpen, which has been one of the weakest in baseball with a collective ERA over five, remains a liability that manager Bud Black has struggled to manage, often forcing the offense to produce late runs to salvage contests. Still, the Rockies have shown resilience at home, playing opponents tighter in Denver where their hitters feel comfortable and their offense tends to elevate output, which could neutralize the Marlins’ perceived pitching edge.

The Rockies’ defense has been shaky, contributing to their struggles by extending innings, but the energy of young players fighting for future roles provides a layer of motivation that can’t be discounted as the season winds down. With the betting markets heavily favoring Miami, Colorado will relish the underdog role, especially with the opportunity to spoil another team’s September goals while evaluating their own young talent under the microscope. Gordon’s task will be to limit damage early and hand the game over with a chance, which means relying on inducing groundballs and attacking the strike zone, something he has not consistently managed but must accomplish against a Marlins team that thrives on patient, opportunistic hitting. For the Rockies’ faithful, these final home games are less about standings and more about glimpses of what the future could hold, as players like Jones and Doyle look to cement themselves as long-term cornerstones. Even in a season defined by losses, Coors Field provides Colorado with an element of unpredictability, and if their offense can heat up while the bullpen avoids implosion, the Rockies could easily turn this matchup into one of the surprise upsets that punctuate the final weeks of the season.
