Key Storylines

Pitching Matchup
Logan Gilbert has been a steady presence for Seattle. Through 19 starts he is 4-5 with a 3.69 ERA. His WHIP sits at 1.03 and he has a strong strikeout rate. He is a solid option against Cleveland and will need to step up to navigate the middle of their order.
Gavin Williams has been a workhorse for Cleveland. He is 8-5 with a 3.36 ERA in 26 starts and has logged 136.2 innings with 135 strikeouts. Williams has a power fastball that makes him tough on right-handed hitters especially.

Final Thoughts
Both starting pitchers should perform well again in this game. Things will get interesting once the bullpens get involved.

I’ll take the Guardians as a slight moneyline underdog at home in this American League matchup.
