Situational Edges

Raymond Report Angle

Skubal’s been nails — 15-5 SU last 20 team starts, and the Tigers have covered seven of their last ten as a short favorite. Seattle, meanwhile, has lost five of their past seven when facing left-handed pitching, and their offense has gone quiet (3.1 runs avg last 7).

Kirby will keep them close early, but his 4.84 ERA at home vs. LHP-heavy lineups is a red flag. Detroit’s lineup is making better contact (team AVG .274 last 5 games) and the bullpen is rested.

Prediction

• Score Projection: Detroit 4 – Seattle 2
• Lean: Tigers -138 (ML)
• Run Line: Detroit -1.5 (+125 value if you’re bold)**
• Total Lean: Under 6 (Playoff pressure + ace tempo = low variance)

🧾 Raymond Report Key Numbers

• Detroit After Win: 21-24 SU, but 9-2 with 1 day off (ideal prep spot).
• Seattle After Loss: 20-13 SU at home — good bounce-back record, but only .216 AVG vs LHP this month.
• Detroit vs AL West: 8-10 SU road team record but 2.95 ERA — deceptively strong.
• Seattle vs AL Central: 12-6 SU team record — good matchups historically, but Detroit has momentum.

👉 Detroit Tigers -138 ML & Under 6
(Pitching + momentum edge + Under cycle = profitable combo)

📊 Takeaway:
Game 5’s are built on nerves, not names. Detroit’s bullpen and left-handed ace give them the edge. Seattle’s crowd will be loud, but numbers don’t yell — they whisper “Under.”

🎯 Final Call: Detroit 4 – Seattle 2 (Under 6 Cashes)
