Games can turn on the littlest of things.
Take todays game for example,
If Posada doesn't walk in the 8th, Duncan doesn't PR for him. And Molina doesn't come in to catch in the 9th.
And Gimabi doesn't PH for him. But that is what happened and well GAME WINING HR IS THE RESULT.
If Posada stays in the game then Giambi doesn't PH as maybe we don't get the same result.
