Quick answer: Corey Seager has one of the cleanest left-handed power profiles in MLB. His daily board: HR over 0.5 (+260 to +400), total bases over 1.5 (-115 to -135), hits over 1.5 (-130 to -150), and RBI over 0.5 (-130 to -170). The edge lives in his pull-side power against right-handed pitching at Globe Life Field, which plays HR-friendly with the roof closed.
What Drives Seager’s Power
Pitcher handedness matters most. He crushes RHP regardless of pitcher type. Lefty starters cut his HR rate 20-25%. Globe Life with closed roof plays as a launch park; open roof plays neutral. Weather: warm-weather games inflate his power 8-12%.
TB and Hits Pricing
TB over 1.5 hits ~60-64% neutral. Hits over 1.5 hits ~55-58%. The HR prop is the highest-EV market when matchup factors stack favorably.
Where the Sharp Edge Lives
HR over against RHP fly-ball pitchers at Globe Life with closed roof. TB over in launch conditions. Avoid betting against him in lefty matchups; the platoon disadvantage shows up in his expected stats.
Common Mistakes
Betting Seager HR over against lefty starters (10-15 percentage point drop). Ignoring roof status (closed vs open meaningfully changes his park factor). Chasing primetime hype.
