Balls per Wicket: Balls divided by Wickets
Total number of Balls faced by a Batsman, which is divided by his Wicket(dismissal) in an Inning.
This indicator is very useful and informative for Test matches, as Batsmen can be measured for their staying ability, and one can find out the Average number of balls they prize themselves to get dismissed per inning.
Example
M.Slater vs Pakistan (Aust in Pak 1998)
Inns : 5
Dismissed (Wkts) : 5
Total Runs 238
Total Balls faced: 567
FORMULA
Balls / Wkt : 567 / 5 = 113.4
