XVAL is the common language for describing the concept of Moneyball in equal terms. When you hear about a big trade or contract extension, have you ever wondered if your favorite athletes or rival players are paid what they’re actually worth? XVAL uses a formula consisting of several advanced baseball statistics to determine (1) the value of a win in MLB and (2) whether each player’s salary is above or below the value of wins they have delivered.
Try it for yourself! Select any two players in MLB in the interactive visualization below to compare the eXcess VALue they delivered for their teams last season. For more on XVAL and the latest updates on the upcoming 2013 MLB season, follow XVAL on Twitter.
