The Pirates have reached the finish line of their final sprint. With Saturday's win over the Reds the Pirates locked down the number 1 wild spot and will play the Reds in PNC Park on Tuesday. If the Pirates win that game all we know is they will not play the Dodgers in the NLDS.
The Cardinals won last night and the Braves lost so the Cards now have the best record in the league. If that holds the winner of the Pirates-Reds game will play the Cards.
