They can not lose this ballgame. That combo there can let the Guardians score 5 runs in no time. They absolutely have to treat this like a playoff game. I've use Graveman in the 9th.
I think how a manager moves the pieces can make a big difference. In a “must” win game, kopech and hendriks covering the last 5 innings after getting the 4-2 lead sounds like a plan much better than (tired) crochet/bummer/tepera/kimbrel. I mean does he know it’s a 5 game series?
