AL tie-breaker sites determined:

A series of coin-tosses was conducted today by Major League Baseball to determine the sites for potential two-team tie-breakers to clinch the American League East, the AL Central, the AL West and/or the AL Wild Card berth. ...

Opponents Site
NYY-BOS Yankee Stadium, New York
NYY-CLE Jacobs Field, Cleveland
OAK-NYY Yankee Stadium, New York

As a point of clarification, if three clubs finish the season with the same winning percentage and one team will be a division winner and another will be the Wild Card, the games will be played as follows:

• The two teams tied for the division lead will play the one-game tie-breaker, with the winner being declared the division champion.

• The losing team will then play the club from the other division for the Wild Card.

So, if we tie with Boston for the division or Oakland for the wild card, we'll have home field advantage in the tie breaker game. If we tie with Cleveland for the wild card, we'll have to go to Cleveland.
