The Mariners Rest Cole Young Against a Depleted Rockies, And the Over Just Got Risky
Cole Young is getting the night off as the Seattle Mariners host the Colorado Rockies in Game 155 at T-Mobile Park on September 19, 2026. He’s not alone: both dugouts are stripped to the studs by injury and late-season attrition. That’s a recipe for suppressed offense, and it hits every betting market from the full game total to team and player props.
The BDL injury log covers it: Seattle sits Young, Emerson, Donovan, Raley, Hancock, Wilcox, Brash, Davila, and Wilson. Not to be outdone, Colorado has lost Willi Castro, Dollander, Herrera, and is running one of the weakest lineups in baseball. The Rockies have gone 1-9 in their last 10 and sport a hideous -178 run differential. You’re looking at a matchup between two of MLB’s least potent orders right now.
This matters for your wallet. Any market or prop still pricing in full-strength offenses, or clinging to the Coors Field effect, is lying to you. It’s a different story in Seattle and an even more extreme one with these lineups. The over is a trap, especially if sportsbooks are slow to move team or game totals post-lineup announcements.

Colorado isn’t just bad, they’re historically feeble. In the last 10, the Rockies are 1-9, and their offense has cratered. Injuries to Willi Castro and bullpen arms strip away any depth, so even garbage time runs can’t save an over ticket here. The Mariners, for their part, limp in at 5-5 but don’t have the firepower to take advantage. With Young sitting, Seattle’s lineup is hollowed out right at the top. They’re averaging 4.08 runs per game on the season, and without a sparkplug bat like Young or any credible bench depth, those numbers are heading south fast.
This game is not in Coors Field, it’s at pitcher-friendly T-Mobile Park. Any public move toward an over is inertia, not insight. Sharps know it: the total opened low and any upward movement based on outmoded assumptions is value ripe for fading. Don’t buy into “someone has to break through eventually.” This injury sheet, and the run histories, say otherwise.
- Cole Young and multiple Mariners regulars sitting: the offense is capped and player prop overs are inflated by name value.
- Rockies missing Willi Castro and bullpen depth: team total unders are firmly in play as run production dries up late season.
- Seattle’s run average (4.08) already mediocre: slips further without Young and Raley.
- Colorado is 1-9 in the last 10 with a -178 run differential: fade any optimistic run lines.
- Game played in Seattle, not Coors: look for strong pitcher metrics to suppress scoring further.
Key Takeaways for Mariners vs Rockies Game 155
- Back the under on full game total (likely 7.5 or 8) with depleted lineups on both sides.
- Fade Mariners team total overs until key bats return.
- Pass on any Cole Young-related prop, he’s out, and so is the value.
- Rockies team total unders have an edge with star hitters and bullpen arms sidelined.
- Do not assume late-season call-ups or bench bats will save the over, let the injuries guide your risk.
- Monitor late bullpen news, but only commit to the over if both teams surprise with healthy lineups (unlikely).
