Anyway, here is some fielding data. I've replaced the in-season cumulative UZR with Chris Dial's Defensive Runs Saved. You can find an explanation of what he's up to here. UZR/150 is the current UZR extrapolated to 150 games. RZR is Revised Zone Rating, which is like a fielding average but counts balls hit into a zone, rather than those the fielder actually reached.

Harper commented after the last fielding review on how we need more like three years' data to get a sense of a player's talent as a fielder. This is true, but one of my old-fashioned sabermetric principles is that we should be more interested, as fans, in what happened rather than what we can expect to happen. Over three years, Dunn might turn out to be the worst first-baseman in the league. However, for the moment he's been doing better than I thought we had any right to expect. I'll keep singing praises for his effort and dedication so long as he keeps that up — and even if he starts having difficulties, because he's clearly trying his best. Jolly good show!
