Lee gets to a lot of balls that are generally out of the 1B zone (OOZ), where he's 4th in the NL. However, he leads NL 1B in fielding errors with 5, and is third worst among NL 1B in all errors with 6 (Votto 8, Delgado 7). His overall fielding rating (RZR) puts him a distant 4th in the NL, in a cluster with Adrian Gonzalez, Todd Helton, Mark Teixeira, Ryan Howard and Joey Votto (who gets to a TON of balls OOZ). The best defensive 1Bs, this year, by far, to this point, have been Pujols and Berkman. That cluster of 6 is in the middle, average to above average, and the other 6 1B (Adam LaRoche, Carlos Delgado, Prince Fielder, Conor Jackson, James Loney and Mike Jacobs) are below average. So yes, Lee has been average to above average in the field this year.
