It's still the subject of some controversy, but most everyone agrees that Bill James's Win Shares are a bold new addition to statistical measurement of a baseball player's worth to his team. The good folks at Baseball Graphs are keeping a daily watch on 2003 Win Shares, which some purists will tell you is wrong-headed because WIn Shares are only supposed to be based on a full season. Nonetheless, it's interestiong to see the player whose name tops the American League WS charts with 24 -- and the player who's tied with him. IMO, these are your two front-runners for AL MVP this season.
