Colorado Rockies (57-102) at Chicago White Sox (83-77) | Saturday, September 26, 2026 | 6:10 PM CT | Rate Field, Chicago, IL
There’s a small piece of nostalgia tucked into tonight’s lineup card for longtime Sox fans: Jose Quintana, who broke into the majors with Chicago back in 2012 and spent five seasons anchoring this rotation before getting traded to the Cubs in 2017, is back at Rate Field tonight — just wearing Colorado purple instead of black and white. As a Sox fan, I’ve always had a soft spot for Q, but I’m not feeling sentimental enough to ignore what his sinker has actually been doing this season.
Here’s my real breakdown of tonight’s matchup — the specific pitch-level data and situational trends that matter more than just riding Friday’s win into another expected result.

Quintana’s Sinker Has Become a Real Liability
Here’s the specific number that stood out digging into tonight’s matchup: Quintana’s sinker is generating a .454 expected weighted on-base average against this season — an ugly figure for what’s supposed to be his primary weapon for inducing weak contact. Paired with a 1.51 WHIP and a 5.40 ERA, this isn’t the crafty lefty who once anchored a Chicago rotation; it’s a pitcher whose signature pitch has stopped working the way it needs to. If Chicago’s hitters are sitting on that sinker early, tonight could get out of hand in a hurry.
Davis Martin’s Workload Advantage Is Real
Davis Martin brings a genuinely different profile to the mound tonight — 145.1 innings on the season, more than three times what Quintana has logged, with a 3.84 ERA, 1.29 WHIP, and a strong 7.49 strikeouts per nine. That volume matters this late in the season; Martin has been a full-time, reliable member of this rotation all year, while Quintana has been fighting his way back from a sprained elbow that cost him significant time earlier in the season.
The Resilience Stat Worth Knowing
Here’s a number I think gets overlooked with a team riding this much momentum: Chicago has won 46% of its home games this season even when the opponent scores first — the third-highest rate in baseball. That’s not really relevant if Chicago jumps out early tonight, but it’s a good reminder that even if Colorado somehow gets on the board first against Martin, this White Sox team has shown all year it doesn’t panic.
Colorado’s Pitching Staff Has Been Historically Bad
It’s worth putting Quintana’s individual struggles in context: Rockies pitchers carry a 5.84 ERA at home this season, the second-highest mark in the league, and opponents are hitting .289 against Colorado’s staff overall — the highest opponent batting average allowed in baseball. This isn’t a case of one struggling pitcher on an otherwise solid staff; it’s a team-wide issue that’s been the story of Colorado’s season from the jump.
What Actually Decides Tonight
I think this comes down to whether Chicago’s lineup does what a motivated, power-heavy offense should do against a struggling sinker from a pitcher who’s given up hard contact all year. Martin’s workload and results give Chicago a real edge on the mound too, and a model built on this season’s full body of work has White Sox win probability sitting north of 71%.
My Final Score Prediction: Chicago White Sox 8, Colorado Rockies 2
