Fangraphs is now tracking WPA stats for all players.

Fangraphs, which has been generating Win Probability Totals graphs for every game, is now collating the Win Probability Added (WPA) totals for all players and listing them on the team pages.

I know David plans to develop a "WPA leaderboard" soon, but I thought I'd jump the gun and list the top 10 WPA leaders, based on a quick review of each team's list. Remember that every 50 WPA points is a game above average.

Player           WPA
Pujols           323
Swisher          195
Carpenter        183
Chavez           171
D. Sanchez       157
Jeter            156
Ensberg          155
V. Martinez      151
Papelbon         150
Gomes            148

You could almost field an entire team from this list, with a starter (Chris Carpenter), setup man (Duaner Sanchez) and closer (Papelbon) on the mound, a catcher, first baseman, shortstop, third baseman (two, actually) and a couple of outfielders. Biggest surprise to me is the Mets' Sanchez, who has given up no runs in 17 innings and pitched in some high-leverage situations.

Other totals of note include Barry Bonds (138, despite the low batting average), Lance Berkman (138 too), the Reds' Todd Coffey (137!!) and Tampa Bay's Ty Wigginton (130!!!!!).
