Stephen Kolek under 3.5 strikeoutsW

Jul 2, 2026 ET · Odds at publication 1.5600

Read original reasoning

Kolek's 2026 K/9 is 5.88 (34 K in 52.0 IP) and his last three starts show 0, 4, and 3 Ks. He's returning after an extended absence for a family emergency and paternity leave — conditioning and pitch count are genuine concerns; a limited outing suppresses his K ceiling further. TB is a hot offense (.261 team AVG, 4.6 R/G) on a 7-game win streak. Market already prices this -179 because the data is clear, but the contextual risks are additive rather than priced in fully.

Kolek's 2026 K/9 is approximately 6.1 (34 K in 50.1 IP) — below-average whiff rates for a starter. His last three starts vs STL specifically: 3 K (May 17 2026), 2 K (Jul 27 2025), 3 K (Apr 01 2024). All three well under 3.5. STL pitching staff posts 7.70 K/9 against, suggesting their lineup makes contact at a moderate rate. With Kolek rarely punching out STL hitters in their matchup history, under 3.5 at -127 is the lean.

Read original reasoning

2026 season: 30 K in 43 IP (6.28 K/9), which averages out to ~4.3 Ks per start — over the line. Last 3 starts: 3, 8, 5 Ks — two of three cleared 3.5. HOU lineup posts .244 AVG and .733 OPS (league-average offense), offering no strong resistance. Kolek went 7.0 IP with 8 Ks just two starts ago vs CIN. The floor is real (3 Ks vs TEX June 9) but the season average and recent peak outings support the over.
