Wikipedia
Strike rate refers to two different statistics in the sport of cricket. Batting strike rate is a measure of how frequently a batsman achieves the primary goal of batting, namely scoring runs. Bowling strike rate is a measure of how frequently a bowler achieves the primary goal of bowling, namely taking wickets (i.e. getting batsmen out).
Both strike rates are relatively new statistics, having only been invented and considered of importance after the introduction of One Day International cricket in the 1970s.
