The Edge
Miller's elite ERA and Seattle's across-the-board pitching and team quality edge justify a lean toward the Mariners ML, but the brutal home ATS record and key injury concerns cap this at a LEAN rather than a PICK.
Key Factors
Pitcher ERA gap: Miller at 1.54 ERA (3-0) vs. Suarez at 3.21 ERA (2-3) — a 1.67-run delta that clears the 1.5+ threshold for a significant starting pitcher edge
Seattle team ERA (3.62) and WHIP (1.18) both superior to Boston's (3.92 / 1.28), suggesting bullpen depth advantage as well
Seattle's overall record (39-37, .513 win%) vs. Boston's (29-43, .403 win%) reflects a meaningfully better team across the full season
Boston on a 4-game losing streak, going 2-8 ATS in their last 10, while Seattle is riding a W1 streak with a positive run differential (+0.3 vs. -0.2)
