Measuring speed in baserunning wasn’t a precise metrics for many years.
Today they define this category as a statistic that takes stolen bases, caught stealing and other baserunning plays into account and turn them into a value above or below league average.
How is BaseRunning (BsR) calculated?
Weighted stolen bases+Ultimate Baserunning+Weighted Grounded into Double Plays Runs.
The next question is, what is (wSB)weighted Stolen bases?
It uses the league stolen base data to estimates the number of runs above or below average a player contributes to his team by stealing bases or getting caught stealing.
(UBR) not to be confused with the ride sharing service UBER.
This gives credit for advancement on the bases relative to the frequency with which the league average runner advances in the same situation.
Weighted Grounded into Double Play (wGDP)
this calculate the extra out a player saves or costs his team by hitting into fewer or more double plays than the average player with the same number of opportunities.
Why is this used? with stolen base attempts on a continual decline- and the are of baserunning extending beyond stolen bases- it better to look at a context driven and encompassing stat.
Since I mentioned a decline in stolen bases, let’s look at it historically.
