KANSAS CITY, Mo. — At 8:53 Central Bumgarner Time here, a certain 6-foot-5 left-handed San Francisco Giants pitcher walked from the bullpen to the mound in Kauffman Stadium to provide a little Show Me to Missouri. It’s said in this town that half the kids in the city would dress up as Madison Bumgarner for Halloween but their parents won’t let them because it would be just too darn scary.
