A UZR-less 2012
If you visit FanGraphs or Baseball-Reference during the baseball season, it's tough to avoid exposure to defensive statistics like UZR, DRS or TZ. They feature prominently on individual player pages and leaderboards. Their existence is mostly beneficial, especially in the long term. A look at the...
Tuesday Rockpile: Carlos Gonzalez - Glove of Gold or Pyrite?
Carlos Gonzalez sure looks pretty playing the outfield. He has a laser arm (led the league with 12 assists), can play all three positions, has good speed, and isn't afraid to slide, jump, crash or dive in order to haul in a fly ball. He does this. He is all you can want toolwise as an outfielder,...
Early UZR Check: Royal Outfield Looking Surprisingly Bad
Let's get this out of the way: 1) it's early 2) small sample 3) defensive stats are sure crazy aren't they? This year's defensive outfield can help us understand why the Royals have had so much trouble getting to .500. Over at Fangraphs you can look at the UZR numbers for an outfield as a whole....
Defense and the 2010 Giants
I don’t know quite how to read this chart: Well, I have a guess as to how it should be read – it involves some peyote, an Emerson, Lake, and Palmer album, and an experienced guide – but that’s just a guess. It seems, though, that it means good things for the Giants....
Is Nyjer Morgan's Defense Off This Season?
When I took a look at advanced fielding stats last week, I noticed that Nyjer Morgan was well below league average at CF--for the second update in a row. "Coincidence," I thought, "statistical fluke." UZR takes time to settle down, and a few early misplays might skew things. Then I saw last...
Royals UZR/150 Projections for the 2010 Season
Earlier this year I released my own set of UZR/150 projections. Now that the Royals have finally set on the basics of a roster, let's look at how the players project to do defensively this season. Here is a list of how each player projects to do at each position they have played previously over...
Is There Any Hope For Luis Castillo's Defense?
It appears Luis Castillo will be the Mets' primary second baseman in 2010, despite reported attempts by the front office to trade him this offseason. Moving Castillo for basically anything (except Gary Matthews Jr.) and targeting Felipe Lopez or Adam Kennedy was/is the smart play, but there haven't...
Saber 101: Ultimate Zone Rating
Perhaps the most coveted part in Sabermetrics -- that is the study of baseball through advanced mathematics and statistics -- is quantifying defense. This isn't a new fascination, either. More than 110 years ago, a simple journalist set about to try to quantify what runs should be credited to the...
Project Jason Bay's Defense
Defense will play a pivotal role in determining if 31 year-old Jason Bay is worth his massive contract. Given the following information, project his corner outfield defense: (he played about 150 games each of the last three seasons) UZR -13 runs in 2009, -42.9 runs from 2007-2009 Fans projection:...
