I have great respect for Sane Bieber. However, I'm not going to turn down this price on the home underdog Mariners. 

Seattle is 31-13 (70 percent) the past 44 times when facing a righty starter. The Guardians are 0-4 in their last four contests against Seattle. 
Bieber is 1-2 with a 3.75 ERA in four career starts versus the Mariners. 

Logan Gilbert is 10-5 with a 3.52 ERA. He hasn't pitched as well during his last eight starts as he was earlier in the season. However, half of those outings were against the powerful Astros and Yankees. This is a step down in class for Gilbert. The Guardians rank 16th in runs and 29th in homers. 

Gilbert is backed by a bullpen that is 51-0 when leading going into the final two innings. That's the best in the majors.
