Our Criteria here: Win - a given team wins the game if they were losing/tied (in this order) in extra innings, 9th, 8th or 7th inning. Loss - a given team loses the game when they were winning/tied in extra innings, 9th, 8th, or 8th inning.
ZScore: is based on the population standard deviation and mean here. It tells you how many standard deviations from the mean you are. For wins, a positive ZScore is what you want as that relfects "you came back to win more than others". So 1.5 is better than 0.5. For the loss, a negative ZScore is what you want as that reflects "you did not lose your leads like others around the mean". So -1.5 is better than -0.5
