UZR on Fangraphs: using BIS on Ichiro

By Tangotiger

If this isn’t the greatest news since the launch of Fangraphs itself: UZR, going back to 2002, available on Fangraphs. The very first guy I went to was Ichiro.

UZR, using BIS as the source, since 2003, has Ichiro as +33 runs in RF (+7 runs per season) and 0 in CF. Using STATS as the source, he’s +14 in RF (+3 per season) and -24 in CF (-13 per season).

That, ladies and gentlemen, is the reason that fielding metrics are considered so untrustworthy.
