Foster Griffin

Griffin's season K/9 is 8.49 (165 K in 175.1 IP), but outing length is the critical variable. His last three starts: 2.2 IP (Oct 07), 4.0 IP (Sep 15), and only 6.0 IP in the most favorable of the three. The market has under at -130 vs over at -108, reflecting the IP uncertainty. Tampa Bay's lineup is stronger than Cleveland's — .258 AVG and .728 OPS as a team vs a lefty who has allowed 23 HR. In a low-run, ALCS context where Guardians manager Vogt may have a short leash, Griffin exiting before the 4th inning completes would likely strand him at 3 or fewer Ks. The risk of an abbreviated start — as seen in his Oct 07 postseason appearance — makes under 3.5 the defensible side at this price.

Griffin's last 3 starts: 5 K in 4.0 IP (ND CHW), 4 K in 2.1 IP with 8 ER blown (L BAL), 3 K in 6.0 IP (ND DET) — declining K count, sharply shortened outings. The 15.5 outs line has Under at -185, implying roughly 5.2 expected innings. Even crediting his season K/9 of ~8.15, a 5-inning cap limits his ceiling to around 4-5 Ks total. Three consecutive abbreviated or disaster starts with a clear downward K trend makes the under the correct side. BOS hitters have no career matchup data against him, so no historical suppression edge exists to chase the over.

Griffin's last 3 starts produced 4K, 3K, and 4K respectively — all under the 4.5 line. His Sep 9 outing (2.1 IP, 8 ER) introduces real early-hook risk that would cap Ks again. Post-deadline ERA has climbed to 5.94 vs. his 3.65 season mark, signaling genuine recent decline despite a 4.12 FIP. CHW average 4.7 R/G (150 GP) and can generate baserunners that pressure Griffin's pitch count, limiting innings and strikeout volume. Three consecutive sub-4.5 outings plus outing-length uncertainty makes this the clearest edge on the board.
