May 26, 201313 yr There have been a lot of new measures in the last decade. Many help frame the game of baseball in new ways. WPA - Win Probability Added tries to measures a players impact on winning games. Earlier this week Mike Trout hit for the cycle and stole a base. His WPA for the game was -0.012. His performance that day decreased the probability his team would win the game. Jose Bautista posted a WPA of over 1 in his two homeruns walk off performance earlier this week. I am not sure what that means, but the Blue Jays sure could use two wins for one given their rough start. still interested?
