On Playoff chances, It looks like the Rays and Astros are currently good to go, plus one of the Mariners, Red Sox and Blue Jays in AL. The Sox season can swing on what happens in the 7 games with the Astros , the 5 with the Rays, and 3 in Toronto yet to play. Fortunately we also get 7 shots at the Yankees .
The chase with Blue Jays is as follows: The Jays at 119 games have two fewer losses . Assuming wins for them, they should be considered 4 up on the 42 games left Red Sox. If the Sox play at a .600 clip that would produce 25 wins . If Toronto goes .500 over their last 44 , BJ's will finish at 89 wins . Given my scenario , the Sox will have 88 wins and miss the PO's.
So everytime you see a 2 out walk, poor AB, idiotic baserunning, or defensive misplay realize just how tight the Sox prospects actually are. Of course, this doesn't take into account collapses or extended runs by similar teams.
