Tampa Bay Rays at Seattle Mariners (2026-08-09). Ian Seymour vs Emerson Hancock at T-Mobile Park.
Starters — Seymour has a 4.27 ERA and 1.13 WHIP over 84.1 innings, with strong bat-missing ability at 10.57 K/9. His control is solid at 2.99 BB/9, but the main risk is power contact allowed, shown by a 1.39 HR/9. Over his last three starts, he has allowed 4 earned runs in 16.2 innings with 20 strikeouts and 2 walks, including a 6-inning, 2-earned-run, 9-strikeout outing on August 3. His recent trend is down, which points to improving form. Hancock enters with a 3.33 ERA and 1.07 WHIP across 116.1 innings, backed by 8.36 K/9 and excellent control at 2.24 BB/9. He has allowed 1.16 HR/9, a manageable figure given the workload. In his last three starts, he has given up 8 earned runs in 17 innings with 14 strikeouts and 4 walks. His trend is up, suggesting steady or improving performance.
Teams — Tampa Bay brings the stronger offensive profile with a .730 OPS, .258 average, and 515 runs scored. The Rays have also paired that with quality run prevention, carrying a 3.70 team ERA and 1.15 WHIP. Their recent form stands out at 8-2 over the last 10 games, which supports both lineup depth and bullpen stability. Seattle has a .684 OPS, .229 average, and 461 runs, so the offensive baseline is clearly lighter. On the mound, the Mariners remain competitive with a 3.78 team ERA and 1.20 WHIP, numbers that keep them in games even when the bats are quieter. Their 3-7 record over the last 10 games suggests the offense has not consistently supported that pitching.
