Burns has 22 total strikeouts across his first four 2026 starts: 7, 9, 2, and 4. Two of the four cleared 6.5, two finished well below it. The pitch-count cap has held firm at 87 to 92 pitches and the Rockies are a 24% strikeout-rate offense, not a strikeout-elite team. At plus money the under is priced as if Burns was still pitching to his 14.0 K/9 from 2025, when his 2026 average is 5.5 K per start.
Chase Burns has averaged 5.5 strikeouts per start across his first 4 2026 outings on a 86-pitch leash. The line tonight is set at 6.5. The under has cashed in 2 of 4 games and the over has cashed in 2.
The model takes that observed rate, blends it against league strikeout baselines, opponent contact tendency, and the workload constraint, and lands at a 68.4% under probability versus a market-implied 42.5%. That's a 25.9% edge in raw probability terms.
The 2025 baseline is what makes this number look so high. Chase Burns posted a 14.01 K/9 across 44.3 innings last season. That's the rate the book is anchoring to. The 2026 sample is what is actively repricing the projection.
Here is each 2026 outing for Chase Burns. The right-most column is strikeouts against tonight's line of 6.5.
| Date | Opponent | IP | K | BB | ER | Pitches | K |
|---|---|---|---|---|---|---|---|
| Mar 30 | vs Pittsburgh Pirates | 5.0 | 7 | 3 | 0 | 78 | 7 |

Over 4 starts in 2026, Chase Burns has averaged 5.5 K per start. Tonight's line is 6.5. The under has cashed 2 of 4 times. That's the observed rate the model is pricing off of.
The Colorado Rockies carry a 26.7% strikeout rate as a team in 2026. A high-K offense favors over plays at lower thresholds because contact is rarer.
Combined with Chase Burns's 86-pitch workload cap, the under at 6.5 sits inside the structural ceiling.
Honest counter-arguments.
The book is paying you +120 on a side the model has at 68.4%. The market only needs the under to hit 42.5% of the time, but the observed 2026 rate plus the structural workload constraint suggest a higher-than-implied probability. That gap is where the edge lives.
