Prediction
The Seattle Mariners hold a significant edge in this matchup, driven by George Kirby’s elite 3.40 ERA and home dominance against Jeffrey Springs’ 3.65 ERA. The Athletics’ improving offense, led by Wilson and Rooker, could keep it competitive, but Seattle’s pitching depth and Raleigh’s power should secure a victory. The Mariners’ bullpen will likely close out a low-scoring game.
Final Prediction: Seattle Mariners win, 5-2. Raleigh hits a homer, and Kirby pitches seven strong innings.
Best Bets
- Moneyline: Seattle Mariners (-275) – Kirby’s command and home-field advantage make Seattle a strong pick.
- Under 8.0 Runs – T-Mobile Park’s pitcher-friendly setup and Kirby’s dominance suggest a lower-scoring game.
- Cal Raleigh to Record an RBI (+140) – His 47 HRs and recent power surge offer strong value against Springs.
