At this point it's Cole's to lose. He leads in innings, WAR, is barely in second in ERA, second in WPA, fifth in WHIP, and is third in strikeouts. Those are really all the stats the voters care about. It's mostly innings and ERA.
Sonny is behind Gausman, Cole, and is in the same tier as Eovaldi, Ohtani, and Valdez. He will definitely get some votes, maybe top 5 depending on how he and the other guys do down the stretch. Felix Bautista is going to get some votes too; he might end up with 45 saves and leads the league in WPA.
