The Inside the Lines team provides analysis of the 2025 MLB trade deadline, focusing on Josh Naylor’s recent trade to the Seattle Mariners. Naylor’s hitting capabilities, especially against right-handed pitching, improve Seattle’s postseason prospects despite limited changes to their overall World Series odds.
MLB Trade Impact: Josh Naylor Traded to the Mariners
The Mariners have strong pitching but lacked offensive power in recent seasons. Josh Naylor’s ability to hit for average (.292 overall) enhances their lineup significantly. While it improves their playoff chances to approximately 82%, it doesn’t substantially boost their World Series odds, which remain at nearly 9%.
| SEATTLE MARINERS | WIN | WIN% | AL WEST | PLAYOFF | ALCS | WS |
|---|---|---|---|---|---|---|
| w/o Naylor | 88.9 | 54.9% | 32.8% | 79.4% | 17.3% | 8.6% |
| w/ Naylor | 89.2 | 55.1% | 35.5% | 81.7% | 17.4% | 8.6% |
| Diff | 0.3 | 0.2% | 2.7% | 2.3% | 0.1% | 0.0% |
The Mariners’ division odds are compelling, and smart bets could yield substantial returns.
