As far as fielding goes...Pujols has zero errors, Lee has committed two errors (most of any first baseman in the majors). In the interests of fairness, Lee has much, much better range at 1B than Pujols and has to deal with erratic throwing from Ramirez and Cedeno on a regular basis (which he deals with quite excellently). I don't think any 1B could ask for a better defensive 3B than Scott Rolen right now, ya know? Much, much better? I dunno about that. Lee is taller and has a longer reach...but I wouldn't say his range is THAT much better than Pujols'. If Lee wasn't in the NL, Pujols would challenge for a gold glove...he's a very good fielder. Usually though, if a poor throw isn't handled cleanly by the 1st baseman, the error usually goes to the person who threw the ball...not the first baseman. But I couldn't tell you on what types of plays Lee's errors came on this year. And you are correct. Rolen is solid at 3rd base...and Pujols does benefit from that. I think Pujols is a good all-around player and quite possibly one of the best hitters to come along during this generation of hitters. However, his defense is above average and I think he receives way too much hype for it (thank you Tony LaRussa). He's not a butcher, but he doesn't have a vacuum cleaner in his glove. Off the top of my head, Lee and Helton are the defensive class of the 1Bs in the NL. I haven't been paying enough attention elsewhere around the NL to know if there are any other really good ones, though. Ditto the AL, for that matter. Errors are typically subjective in their nature and in Lee's case, my memory is that both errors he's been charged with this season were correct in their scoring (especially since one was a strangely dropped ball). I remember being shocked seeing those two errors, as a matter of fact. That said, there is a lot to be said for having excellent defense on the infield. Having guys like Vina, Renteria, and Rolen (and on occasion Matheny) can really help your image, ya know? Especially considering that Rolen is probably the best defensive third baseman of this era (with great consideration for Eric Chavez). Pujols hasn't had to dig out or leap for as many errant throws as Lee, so it's been hard to judge his effectiveness in that regard. Lee, on the other hand, has had to deal with some utter lunatics in the infield. Almost all Cubs fans will tell you that he's saved this team an incredible number of errors because of his extraordinary instincts and reach. I never got that impression from Pujols when he's had to make extraordinary efforts to field a bad throw. How's Pujols' arm, out of curiosity? That's one of the most underrated aspects of Lee, his surprisingly strong and accurate arm. It really helps when it comes to turning the 3-6-3 DP. I'm curious as to whether Pujols' is comparable.
