Bowling average

Bowling average is a statistic measuring the performance of bowlers in the sport of cricket.

A bowler's bowling average is defined as the total number of runs conceded by the bowler divided by the number of wickets taken by the bowler, so the lower the average the better. For fast bowlers in Test cricket, most need to maintain an average of below about 30 to hold a place in the team. Bowlers who maintain an average of below about 25 over a long career are exceptional. The very best in the modern game have averages just over 20. Acceptable averages for spin bowlers tend to be a little higher ranging between 25 and 40.

Career records for bowling average are usually subject to a qualification of a minimum number of balls bowled or wickets taken, to avoid including artificially high or low averages resulting from a career spanning only a few matches. Under the usual qualification of at least 2,000 balls bowled, George Lohmann has the lowest Test bowling average, with 112 wickets taken at an average of 10.75. It should be noted that Lohmann played in the late 19th century, when pitch conditions were far more favourable to bowlers than is currently the case. Only 11 other bowlers have averages below 20 on this basis.

In terms of assessing the effectiveness of a bowler, the average gives a useful but not a complete picture. Another useful statistic is the bowling strike rate - the mean number of balls bowled between wickets.

Bowling averages in One-day Internationals are generally somewhat lower than in Test cricket because the batsmen need to score runs more quickly which makes it easier to get them out. In one-day cricket, the bowler's economy rate is another informative statistic.
