Matchup Breakdown

Dodgers: Sheehan (6-3, 2.86 ERA) struck out 10 across seven scoreless innings in his last outing vs San Francisco. He’s walked only one batter in September and has already shown success against Seattle, tossing three scoreless frames in relief last year. With the Dodgers locked into the NL’s No. 3 seed, lineup rotation is possible, but Freddie Freeman and Shohei Ohtani continue to anchor the order.

Mariners: Seattle hasn’t announced a starter, but their bullpen and rotation depth are set with playoff positioning secure. Offensively, Suarez and Julio Rodríguez have powered an attack that has outscored opponents 89-41 during their 17-1 run. Seattle’s 11-game home winning streak has made T-Mobile Park one of baseball’s toughest environments this month.

Injuries and Conditions

• Dodgers: Clayton Kershaw (retirement tour) won’t start but remains in the clubhouse. No key new injuries.
• Mariners: Healthy roster, resting regulars is possible given their bye.

Best Bets and Prediction

Seattle’s streak and home dominance balance against Los Angeles’ depth and Sheehan’s current form. Motivation could be the swing factor: the Mariners may rotate bats, while the Dodgers have little incentive after clinching.

Projected score: Mariners 4, Dodgers 3
Best Bet: Mariners moneyline +105
Lean: Under 8 runs (rested lineups, playoff-ready pitching)
