2008 Team Defensive Ranking by UZR

The chart below is a ranking of every Major League Baseball team by UZR. UZR is one of the best statistical measurements of defense yet created. Please note however that defense statistics stil have a long way to go. Still, examining this chart and ones like it that you can find on sites like FanGraphs, Baseball Prospectus and others when your ranking your potential pitching selections can be quite valuable when it comes to guessing on potential breakouts and sleepers.

A team that has dramatically improved it's defense is more likely to findpitching breakouts than the other way around. For those of you unfamiliar with UZR I've borrowed a description from Baseball Think Factory (this link is a good one to read) :

UZR rate is expressed as a fraction of 1, the same as a simple ZR (ZR). A UZR rate means essentially the same thing as a simple ZR � namely the number of balls fielded (turned into at least one out) divided by the number of chances; however, UZR rate is a weighted average of a player�s ZR in each of several zones.

As you will see, UZR rate is really a by-product of UZR runs, and UZR runs is the heart of the UZR system. It represents the value of a fielder�s performance expressed as runs saved or cost, in comparison to an average fielder (actually in comparison to the mean performance of all fielders) at that position, in that player�s league, and during that particular year. UZR runs is the defensive counterpart of Palmer�s offensive linear weights (lwts); thus it can be combined with lwts (among other things) to give you an estimate of a player�s total offensive and defensive value. Any player with an average defensive performance will, by definition, have exactly zero UZR runs.
