"There can't be a more improved player in baseball over the last couple of years -- other than maybe Carlos Pena -- than Kaz Matsui" So says Peter King, who last time I checked isn't a baseball writer, and now we know why. Fire Joe Morgan was all over this, and here's a summary:
Carlos Pena
2006 WARP3: 0.3
2007 WARP3: 11.8
2006 WARP3: 0.3
2007 WARP3: 11.8
Zero point three to eleven point freaking eight.
Kaz Matsui
2006 WARP3: 2.1
2007 WARP3: 5.3
