So far it's a two team race in the AL East with the Orioles and Red Sox dueling for the lead - but the Yankees are trying to get back into the picture.
There has not been a day this season where the Orioles were any more than half a game out of the lead in the American League East. This does not mean they are running away with the division. The ongoing duel for the top with the Red Sox continues for another week.
These two teams have been neck-and-neck for nearly three weeks now. Since April 30, either the O's or the Red Sox have led the division every day and neither one has ever led by more than a single game over the other.
