Seattle Mariners vs New York Yankees

Seattle Mariners at New York Yankees (2026-08-12). Bryce Miller vs Will Warren at Yankee Stadium.

Starters — Bryce Miller has a 3.08 ERA and 0.95 WHIP over 79 innings, with 9.0 K/9, 1.71 BB/9, and 1.48 HR/9. His last three starts: 5.0 IP, 4 ER, 5 K, 2 BB; 5.1 IP, 2 ER, 3 K, 2 BB; 5.1 IP, 5 ER, 0 K, 1 BB. The WHIP and walk rate are strong, but the recent form points down and the home run rate remains a clear risk. Will Warren carries a 4.18 ERA and 1.37 WHIP across 114 innings, with 9.0 K/9, 2.92 BB/9, and 1.18 HR/9. His last three starts: 5.1 IP, 3 ER, 5 K, 1 BB; 6.2 IP, 0 ER, 7 K, 0 BB; 3.0 IP, 6 ER, 5 K, 2 BB. Warren has shown swing-and-miss ability and a better recent ceiling than Miller, but his trend is also listed down because the results have still been uneven.

Teams — Seattle enters with a .681 OPS and 463 runs scored, alongside a .228 team average. The Mariners’ pitching staff has been solid overall with a 3.79 ERA and 1.20 WHIP, but the club is just 3-7 over its last 10 games. New York brings a .720 OPS and 535 runs scored with a .230 team average. The Yankees also hold the stronger run-prevention profile, posting a 3.28 team ERA and 1.17 WHIP, and they are 6-4 over their last 10. From a betting matchup standpoint, New York shows the more complete team profile on both offense and staff results, while Seattle’s edge starts with Miller’s season-long command and WHIP.
