Ultimate Zone Rating (UZR) is which type of empirical analysis of baseball, especially baseball statistics that measure in-game activity, statistic used to measure fielding?
Ultimate zone rating Ultimate Zone Rating (UZR) is a sabermetric statistic used to measure fielding. It compares the event that actually happened (hit/out/error) to data on similarly hit balls in the past to determine how much better or worse the fielder did than the "average" player. UZR divides a baseball field into multiple zones and assigns individual fielders responsibility for those zones.
Injured reserve list The injured reserve list ( IR list) is an official designation used by the National Football League (NFL) and National Hockey League (NHL) for athletes who become injured and temporarily unable to play. It is analogous to the injured list in the Canadian Football League (CFL) or the disabled list in Major League Baseball (MLB). The National Basketball Association (NBA) does not have a direct analog to an injured reserve list, instead using a more general-purpose "inactive list" that does not require a player to be injured.
