Maybe I'm crazy but didn't castro finish 2nd in the NL in errors last year despite missing April. I'd say that's quite bad 2nd in the majors, actually. Two things worth noting: 1) All of the players in the Top 7 of that list are shortstops. Here are the 2010 UZR numbers for those players at SS... Ian Desmond: -8.8 Starlin Castro: -2.1 Cliff Pennington: 9.9 Erick Aybar: -2.0 Alcides Escobar: 3.8 Alexei Ramirez: 10.8 Josh Wilson: -2.1 I don't see much of a correlation between the two sets of numbers, good or bad. Errors some value when viewed in context with other numbers, but they are also highly subjective and should not be the sole basis on which a player should be judged defensively. 2) Starlin Castro just accumulated 500 plate appearances at the age of 20 in a season. Most players his age are either in short season A, low A, or are playing their sophomore seasons in college. You're telling me he's not going to improve? I mean, I can understand if you think he has some defensive issues that he needs to iron out, but he's not even old enough to drink. It's a little early to give up on him as a shortstop. I'm not ready to write him off but I'm not ready to consider him Adam Everrett reborn yet either. I'd rather have a good defensive 1b to help limit potential confidence ruining errors.
