Paul Skenes

Skenes carries a strong 2026 K rate (192 K in 168.0 IP, ~10.3 K/9 on season), but his last 3 starts reveal a sharp recent decline: 2 K in 5.1 IP vs LAA, 4 K in 7.0 IP vs CHC, 7 K in 6.0 IP vs KC — averaging 4.3 Ks over that stretch with two of three going under 6.5. The outs market implies roughly 6 innings of work (-133 under 17.5 outs). Even in a full outing, his recent K production is tracking well below his season pace. STL is a below-average offense (.695 OPS, 4.5 R/G) but not a high-strikeout team — their lineup makes contact rather than swinging and missing. Aligning with recent form over season averages here.

Skenes' 2026 K/9 of 10.28 (185 K / 162.0 IP) looks elite on paper, but his last 3 starts tell the real story: 4 K, 2 K, 4 K — an average of 3.3 Ks, dramatically below the 5.5 line. He has not cleared 5.5 Ks in any of his last three outings. Pittsburgh bullpen was taxed Sept 17 vs MIL (4 relievers used), which could prompt a managed pitch count for Skenes rather than a long outing. KC's offense is contact-oriented (4.2 R/G, 7.40 K/9 allowed by their own pitching staff suggesting a team built on contact). PNC Park run factor 0.96 further suppresses high-leverage strikeout situations. Recent form override: three straight sub-5 K starts makes the 5.5 line a clear fade.

Skenes' 2026 K/9 of 10.51 looks elite on paper, but his last 3 starts tell a different story: 2 K (5.1 IP), 4 K (4.2 IP), 4 K (6.0 IP) — a combined 10 Ks over roughly 16 innings. That's a rolling rate well below the 5.5 line. Shortened outings limit his ceiling: he's been pulled early in two of his last three. Despite two strong prior CHC matchups (11 K, 10 K), the recent form trend is a clear regression signal. At -111, the under is fairly priced given the documented recent slump.
