Seattle has the stronger pitching statistics, but Miami’s offensive advantages and success at home make the Marlins my preferred side.

I’m taking the under 8.5. Seattle enters with a team ERA of 3.55 and a 1.16 WHIP, while George Kirby brings a solid 3.81 ERA into this start. Miami’s pitching staff has also held opponents to a .230 batting average.
