You don't want to kill a pitcher but this is for all of the marbles in game 7. Bumgarner is unstoppable. Attempt to get an early lead; let Bumgarner provide as much as he can give. This is it. He can rest in the off-season.
A smart manager would let him take the mound until he gave all that he had. The Royals bullpen is no joke. This is common sense.
Pitchers are treated with kid gloves, but this is one game for a World Series Title. Bochy is a great manager, but San Francisco can win it with Bumgarner. MLB is too long a grind to leave Bumgarner sitting on the bench.
