It depends on when the tiebreaker would be played. If the tiebreaker is on Monday after the season (which would make sense as AL WC game is on Tuesday), then you actually put yourself in a position where the team's ace can go games 2 and 5, although it's highly likely that team uses their ace on Saturday or Sunday. If they use the ace on those 2 days and advance to the LDS, then the ace is set to pitch game 1 (if they don't start on short rest in WC game or come in relief). What happens if there's a 3-way tie? The 3 teams, prioritized by head to head record, choose spot A, B or C. A hosts B, the winner is the first wild card, the loser plays at C. The second winner is the second wild card team, and the wild card game is played.
