Unless the Jays go far into the postseason, there won't be any baseball games. If the Yankees make the World Series, then you can fly down easily to NYC (only 1 HR flight) to catch a game, though tickets would be super expensive. Pittsburgh is quite close as well (5-6 HR drive). Again, it depends on if these teams make it far into the postseason.
For other sports, you can probably catch an Argos game or TFC game. As well, the Leafs start up in October and could probably catch a Raptors exhibition game.
