It has been a while since the Toronto Blue Jays found themselves in this position - leading the American League East after the MLB trade deadline. They enter Monday's action at 65-48, with a three game lead on the Boston Red Sox.
According to FanGraphs, Toronto has a 60% chance of winning the division while the the Yankees are behind them at 24.3% and the Red Sox are at 14.6%. Last year, the Yankees won the East with a 94-68 record. It might take the Blue Jays a little more to get it done this year, but in order to reach the 94 win threshold they would need to go 29-20 over these final 49 games.
