Secondary average, or SecA, is a baseball statistic that measures the sum of extra bases gained on hits, walks, and stolen bases (less times caught stealing) depicted per at bat. [1] Created by Bill James , it is a sabermetric measurement of hitting performance that seeks to evaluate the number of bases a player gained independent of batting ...
Lead distance: Measures the distance between the base and the runner's center of mass at the time the pitcher goes into his windup on a pitch or pickoff attempt. Secondary lead: Measures the distance between the base and the runner's center of mass when the ball is released by the pitcher on a pitch or pickoff attempt.
The first is outcome oriented. This means that the result of a given pitch (i.e., walk, out, home run, etc.) is a component used to calculate the overall numeric value that describes the quality of the pitch. The other kind of pitch quantification does not consider the outcome of a pitch when calculating quality. Rather, it is batter ...
Base runs will sometimes project many more than three runners left on base per inning, despite the fact that three is the upper limit. For example, if walks have a B coefficient of .1, an inning with 10 walks and three outs will yield an estimate of 10*1/(1+3) = 2.5 runs, meaning that 7.5 runners must have been stranded.
Batting Park Factor, also simply called Park Factor or BPF, is a baseball statistic that indicates the difference between runs scored in a team's home and road games. Most commonly used as a metric in the sabermetric community, it has found more general usage in recent years.
Speed Score, often simply abbreviated to Spd, is a statistic used in Sabermetric studies to evaluate a baseball player's speed. It was invented by Bill James, and first appeared in the 1987 edition of the Bill James Baseball Abstract. [1] Speed score is on a scale of 0 to 10, with zero being the slowest and ten being the fastest.
In baseball statistics, fielding percentage, also known as fielding average, is a measure that reflects the percentage of times a defensive player properly handles a batted or thrown ball. It is calculated by the sum of putouts and assists, divided by the number of total chances (putouts + assists + errors). [1]
Extrapolated Runs (XR) is a baseball statistic invented by sabermetrician Jim Furtado to estimate the number of runs a hitter contributes to his team. XR measures essentially the same thing as Bill James' Runs Created, but it is a linear weights formula that assigns a run value to each event, rather than a multiplicative formula like James' creation.
