I would really like to run some numbers on this, I was on TB earlier today, and they take a 3-2 lead in the top of the 9th... only for Fernando Rodney to give up a game tying HR in the bottom of the 9th to Joey Bats - who happened to go 4-4 w/ 2 HR and 4 RBIs, literally all of the Jays offense.
Additionally I was on the Padres when Jesus Guzman tied the game with a grand slam against Tampa Bay, only to have Houston Street give up a 2 run HR to Evan Longoria in the bottom of the 9th in the trop.
All these closers that I mentioned above, and around the league - John Johnson - Baltimore, Jose Valverde ( this is obvious), Fernando Rodney, Houston Street, Anything LA dodgers related.. add anything you guys feel necessary:
And yet remains a constant: Mariano Rivera, and have to give credit to Jason Grilli "The grilled cheese" have converted every save opportunity.
