Magic Number and Day for the Yankees

July 1 marks a significant day for the Yankees. I believe the stat is that every time the Yankees are leading the division (or league) or July 1 that they have won the division (or league). But I couldn't find actual proof of that so it might simply be that every time they are leading on July 1 they have made the playoffs. Either way it's a good thing and we are not only in 1st place on July 1 but are 6 games up.
