Why Todd Coffey got the win

Because Harang didn't go five innings, the official scorer has the discretion to pick the winner based on which pitcher was the most effective. Don Friske, the official scorer at Wrigley Field, picked Coffey, the only reliever to go more than one inning for the Reds.

Poor old Jonny Coutlangus. I could have sworn that the winning pitcher was the one who benefits from the runs advantage in sequential order. So Coutlangus was the next pitcher to pitch after Zambrano blew the lead, therefore he was the winner. But nope, it's a SUBJECTIVE call. Which sucks. By no means did Coffey not deserve the win, he was the man. No doubt. But don't forget about Jonny.
