Batting Average in Cricket: How It's Calculated and Why It Matters
How cricket's batting average is calculated, why it's the primary batting statistic, its key limitations, and the highest Test batting averages in history — including Don Bradman's untouchable 99.94.
Batting average is cricket's oldest and most important individual batting statistic — a single number that attempts to capture a batter's overall run-scoring quality across a career or series. It is defined simply as total runs scored divided by number of times dismissed. A batter who has scored 5,000 runs in a career with 100 dismissals has an average of 50.00. Despite its simplicity — or perhaps because of it — batting average remains the primary lens through which batters are evaluated across all formats of cricket.
The Formula and the Not-Out Rule
Batting average = Total runs ÷ Number of dismissals. Critically, not-out innings are not counted as dismissals. If a batter scores 100* (not out) in one innings, that 100 is added to the total runs but the denominator (dismissals) does not increase. This has an important implication: lower-order batters who finish many innings not out — often tail-enders who bat at number 9, 10, or 11 and are frequently left stranded when the innings ends — have inflated averages compared to top-order batters. A tail-ender who averages 30 by virtue of many not-out scores of 15–20 is not genuinely equivalent to a top-order batter averaging 30 across full innings.
Why Batting Average Is the Primary Batting Statistic
Batting average is preferred over other metrics as the headline batting statistic for several reasons. First, it rewards consistency: a batter who scores 50 twice is more valuable than one who scores 100 once and 0 once — both have 100 runs, but the consistent batter has not thrown their wicket away. Second, it accounts for dismissals — unlike raw runs totals, it penalises batters who get out cheaply. Third, it accumulates meaning over a career: small differences in average become significant over hundreds of innings, distinguishing genuinely elite batters from good ones. A career average of 50+ in Tests has historically been the benchmark for greatness.
Limitations of Batting Average
Batting average has real limitations as a complete measure of batting quality. It ignores strike rate — a batter averaging 45 at 40 balls per dismissal is consuming more than twice the resources of one averaging 45 at 20 balls per dismissal in T20 terms. It does not capture conditions: averaging 45 in subcontinental batting paradises is not equivalent to averaging 45 on green English pitches. It treats all runs equally regardless of the match situation — a match-saving 50 in a crisis is not distinguished from a flat-track 50 in a winning position. Finally, the not-out inflation issue distorts comparisons between top-order and tail-order batters. Advanced cricket analytics have developed additional metrics (runs above average, batting impact, win probability added) to address these gaps, but batting average remains the starting point for any player evaluation.
Frequently asked questions
Is Don Bradman's 99.94 average genuinely impossible to beat, or could a modern player theoretically match it given modern pitches, equipment, and conditions?
Don Bradman's 99.94 Test batting average is almost certainly permanent as the record — the conditions that produced it are specific to Bradman's era and his particular genius, and no modern player is plausibly on a trajectory to challenge it. But the reasons why are worth examining carefully. The gap itself: the second-highest qualifying average (minimum 20 innings) is Graeme Pollock at 60.97 — a gap of nearly 39 runs per dismissal. To put that in modern terms, Steve Smith is one of the greatest contemporary batters and averages around 59–60. Even he, at peak, is 39 runs per dismissal behind Bradman. No active player is within 35 runs per dismissal of the record. Why the gap is so large: Bradman scored a century every 3rd innings across an 80-innings Test career — a conversion rate of centuries from innings that is roughly double the next best historical comparison. He had three separate innings of over 250 runs in Test cricket. His consistency was not just statistical noise; he was genuinely operating at a different level of run accumulation from every other batter in his era and subsequently. Modern conditions argument: pitches in Bradman's era were often prepared to assist batters (uncovered, but when dry, extremely flat), and some of his biggest scores came on Australian pitches that are faster and more bouncy than those he'd face in the subcontinent today. Modern Test cricket includes more away series in difficult conditions, which tends to depress averages. But Bradman also played in the hostile English conditions of 1948 and averaged over 80 in that famous Invincibles tour. Fairest conclusion: Bradman's average is not just a number to be approached with sufficiently good players and conditions — it reflects a rate of performance that has not been remotely approached in 80 years of Test cricket since. It is likely permanent in the way that some athletic records (Beamon's 1968 long jump, for instance) are not broken but rather made irrelevant by a singular performance that transcended the normal distribution of human achievement.
