Has a 24.2% strikeout rate in 7 starts and is facing a Mariners team with an above-average strikeout rate against lefties in the best park for strikeouts in the league.
L.Castillo u5.5 Ks+110

Even after boosting Castillo due to his increased velocity recently and his home park environment, I still have him projected at just 4.99 strikeouts tonight.
