    i don’t understand how wpa works: alex had 0.947 which makes him ~95% responsible, and giambi had 0.166 which makes him ~17% responsible. that doesn’t add up….can you explain wpa to me a little?

    Sure, Adam. You also have to take into account all the guys with negative WPAs. They took away from winning the game. You had Igawa, for instance, who took away the Yankees chances of winning by 44 percent.

    It is not that Alex was responsible for 95% of the win. There are players who had negative wpa for this game, Igawa probably has an -.6 for the game. The sum of all yankees players wpa for the game must add to .46 if the yanks win a home game, or -.54 if the yanks lose the home game. Typically the sum of the positive contributions will add to more than .46, but still remain below 1.

    But this game was so lost at a point that the change in wpa in the bottom of the 9th inning alone was .812.

    Thank you, Fabio. I should rephrase. His contribution increased the Yankees chances of winning the game by 95 percent.

    I literally threw my dog across the room in excitement when A-Rod hit that ball.

    About time. I’m so happy for him. I hope this is a new beginning for A-Rod, and the fans will support him more than they have.

    Good Job by the Yankees Bullpen so far. The Yankees offense and bullpen has carried the Yankees. The starting pitching had been horrendous.
