An extra game at home and especially away from massive pitcher's park Kauffman in the cold. It's a pretty big difference.
It also gets us the WC team which I think is extremely relevant considering you get away from a teams best pitcher, and the WC race is close enough that we could see a 3 way tie for that final spot, which could result in a team using it's best pitcher Monday in a tiebreaker, 2nd best pitcher Tuesday in another tiebreaker, 3rd best pitcher Wednesday in the WC game, and then if they win their 4th best pitcher could be facing us game 1. Then we get to face their 5th best guy in game 2
Long odds that that happens, but even if it doesn't facing the WC team is a pitching advantage, since usually their best pitcher would already be used, we'd only face them once.
