Team Analysis
San Diego Padres
The Padres enter this matchup at 74–57, but their 31–36 road record signals vulnerability away from home. Their last five games stand at 3–2 with 4.6 RPG, a middling output that doesn’t showcase overwhelming offensive consistency. Manny Machado’s production remains reliable, but the team overall has not translated that into dominant recent results, especially when traveling.
San Diego Padres’ last 10 games are split 5–5 at 4.3 RPG, underscoring an offense that is competitive but not explosive. Ramon Laureano has delivered steady power, yet the Padres have lacked the run-scoring surges to separate themselves from opponents. On the road against a Seattle club that thrives at home, San Diego is positioned as the weaker betting side.

Seattle Mariners
The Mariners stand at 70–61 overall with a strong 40–26 home record, establishing T-Mobile Park as a consistent advantage. Their last five games at 3–2 with 5.2 RPG highlight a lineup that continues to generate runs at a pace that pressures opponents. Cal Raleigh’s power presence has been a central force, giving Seattle the extra-base threat to tilt games in their favor.
Over the last 10, Seattle is 4–6 but still averaging 5.2 RPG, proving that even in losses their offense has remained dangerous. Eugenio Suarez’s run production complements Julio Rodriguez’s all-around impact, ensuring the Mariners maintain balance in the middle of their order. With that scoring reliability at home, Seattle projects as the sharper side against an inconsistent road opponent.
