Top 3 Player Props

Player Prop #1: Cal Raleigh Over 0.5 Home Runs at +280 / Confidence 64%
Raleigh’s power profile thrives in T-Mobile Park night games; Detroit’s depleted pitching staff and recent high-HR allowed rates support the over side.

Player Prop #2: Riley Greene Over 1.5 Total Bases at -115 / Confidence 61%
Greene has maintained strong contact and extra-base rates against right-handed pitching; Seattle’s recent starter tendencies favor elevated production.

Player Prop #3: Julio Rodríguez (if active) or Randy Arozarena Over 0.5 Runs Scored at -130 / Confidence 59%
Leadoff/top-order speed and on-base skills against a Tigers staff missing key arms create a high-probability path to scoring.

⚖️ Analysis Summary

Public heavily loads Tigers +1.5 and the Under while money percentages show sharper respect for Seattle on the moneyline. The Under aligns with both clubs’ recent low-output trends (Seattle 3.9 RPG scored, multiple sub-7 totals). Injury lists thin both sides but hit Detroit’s depth harder. Simulation confirms Under and Tigers +1.5 as the highest-probability spots; fade pure public on the moneyline. Overall scoring outlook leans low due to pitching edges and park factors.

🔮 Recommended Play

Follow the public on Detroit Tigers +1.5 and Under 7.5 — both carry the strongest mathematical probability and positive EV after line and split analysis.
