Who manages Yankees if Girardi leaves?

With no contract in place following the end of the 2013 season, there's a chance this could be Joe Girardi's last go-round as the manager of the New York Yankees. It seems nobody is trying to push Girardi out the door, and given the number of injuries the team has endured this season -- in the team's first 152 games, Girardi has started 132 different lineups -- the fact that the team is still in the playoff hunt is borderline miraculous.
