Career Win Leaders by Age 31

In an issue of Sports Weekly right around Thanksgiving there was an interesting snipet I thought was worth passing along, since right around the time the Veteran's Committee begins tossing around names that have yet to be inducted into Cooperstown, NY, former Chicago Cub third-baseman, Ron Santo's name always seems to be on that list.

Player wins are defined as the number of victories above the average that a player is deemed to contribute to his team, assuming an average player contributes a .500 record. The chart below presents the career leaders in player wins by age 31 up to the midpoint of the calendar year (June 30) during which they were 31. Fielding performance is factored into player-win totals.
This list consists of the top 30 players, some of which are still active.
All of the players on this list are in the Hall of Fame except for Ron Santo and the active players at the beginning of the 2007 season.
