Heroes and Zeroes is a series where I use www.fangraphs.com to rank each player's gameday. It is not meant to say one player is better than any other player. WPA is a context dependent measurement in which each play is judged on it's probable impact on the outcome of the game. It is a statistic that is meant to divide credit amongst the winning team and blame across the losing team. If you were to follow the link at the end of this paragraph, or even add all the numbers in this article together, they will add up to zero. The winning team is responsible for 0.5 wins, and the losing team is responsible for -.5 wins. The statistic has properties such that an 81-81 team, at the end of the season, will have a collective WPA of exactly zero. Source material for today's game can be found here.
