Measuring Success
One of the difficulties in determining how good a player is at stealing bases is whether to judge the cumulative number of steals or the success ratio of steals to caught stealing. Noted statistician Bill James has argued that unless a player can steal a high percentage of the time, then the stolen base is not useful, and can even be detrimental to a team. A success rate of 67 to 70% or better is necessary to make stealing bases worthwhile.
Judging the base-stealing abilities of players from earlier eras is also problematic, because caught stealing was not a regularly recorded statistic until the middle of the 20th Century. Ty Cobb, for example, was known as a great base-stealer, with 892 steals and a success rate of over 83%. However the data on Cobb's caught stealing is missing from 12 seasons, strongly suggesting he was unsuccessful many more times than his stats indicate. Carlos Beltrán, with 286 steals, has the highest career success rate of all players with over 300 stolen base attempts, at 88.3%.

Famous quotes containing the words measuring and/or success:
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. Strong and Sensitive Cats, Atlantic Monthly (July 1994)
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
