FanGraphs has made some great strides in the past few months in their automated production of the WPA graphs. The graphs have been tweaked, and now have demarkations for each inning and the players' line from the boxscore along with their WPA.
They are also tallying each player's gross WPA, which gives an interesting insight. For instance, A.J. Pierzynski is currently smoking the ball (.342/.392/.397), but he checks in with a WPA of -22.8%. This phenomenon is not unique. Last week, as noted over at Black Betsy, A.J was performing similarly poor in their ERV scoring system. This is due to A.J.'s complete lack of clutch.
Meanwhile, you'd be hard pressed to guess who is the Sox 5th most valuable offensive weapon using WPA as a guide.
