Quick answer: Strike rate is runs per 100 balls — it measures speed. Average is runs per dismissal — it measures survival. In T20 the scarce resource is balls, not wickets, so neither number means much alone. Read them together, with the phase the batter operates in and the number of innings behind the figure.
Cricket statistics have never been more visible or more misused. A clip goes viral, a caption attaches a number to it, and within an hour the number is being quoted as though it settles an argument. Most of the time it does not, because the figure has been detached from the context that made it meaningful. This Jai Club guide is a plain-English tour of the T20 batting metrics you will actually encounter, what each one measures, and the specific ways each can mislead you.
Strike Rate: Speed, and Nothing Else
Strike rate is runs divided by balls faced, times 100. A batter making 45 from 30 balls has a strike rate of 150. That is the whole calculation, and its simplicity is both its strength and its weakness. It tells you how fast someone scored. It tells you nothing about whether they lasted, when they batted, or what the situation demanded.
The classic trap is comparing strike rates across phases. A finisher arriving at the seventeenth over faces bowlers under pressure with the field spread and licence to swing at everything; an opener faces the new ball with fielding restrictions but also a hard, moving ball. A middle overs anchor may be batting on a collapsing scorecard where survival is worth more than tempo. Three very different jobs, three very different expected strike rates, and a raw comparison between them is close to meaningless.
Average: Survival, in a Format That Barely Rewards It
Batting average is runs scored divided by times out. In Test cricket that is close to the single most important number a batter has, because the binding constraint is wickets. In T20 the binding constraint is balls — there are only 120 of them — and a batter who protects their wicket by scoring slowly can lose a match while improving their own average.
Two more wrinkles. Not-outs inflate the average of finishers, because a batter who is unbeaten in a chase never has that innings counted as a dismissal. And a small number of very large scores can carry an average upward while the median innings stays modest. Average is worth reading; it is not worth reading first.
| Metric | What it measures | Its main blind spot |
|---|---|---|
| Strike rate | Scoring speed per 100 balls | Ignores dismissals and phase |
| Average | Runs per dismissal | Rewards slow accumulation; inflated by not-outs |
| Boundary % | Share of runs or balls hit to the rope | Undervalues running between wickets |
| Balls per dismissal | How long a batter survives | Says nothing about tempo |
| Phase splits | Where in the innings runs come from | Needs a decent sample to stabilise |
Boundary Percentage and Balls Per Dismissal
Boundary percentage answers a question the headline numbers skip: how is this batter scoring? Two players can both strike at 140, one by hitting a six every eight balls and rotating little else, the other by finding gaps and running hard. Those are different skills with different reliability — boundary hitting is more pitch- and ground-dependent, running is more repeatable but caps out lower.
Balls per dismissal is the quiet companion to strike rate. Speed with no survival produces a batter who dazzles occasionally and fails often. Survival with no speed produces a batter who is technically not out and practically a liability. Looking at the two together is most of what “impact” means before anyone builds a fancier model for it.
Reading a Scorecard in Order
- Check the sample size first — How many innings sit behind the figure? Six innings is an anecdote; sixty starts to describe a method.
- Identify the role and batting position — Opener, anchor, spin-hitter or finisher — the expected numbers differ enormously by job.
- Read strike rate and balls per dismissal together — Speed without survival, or survival without speed, are both incomplete pictures.
- Split by phase — Powerplay, middle overs and death produce different scoring conditions. Compare like with like.
- Look at boundary percentage — It tells you whether the runs come from power or from placement and running.
- Check the competition level — Age-group, domestic, franchise and international records are not interchangeable.
- Verify at the source — Confirm any figure on ESPNcricinfo before repeating it — captions get numbers wrong constantly.
Where to verify: ball-by-ball records, phase filters and career summaries are maintained by ESPNcricinfo. For the format’s rules and history, the Twenty20 International reference is a reasonable starting point.
The Traps That Catch Most People
Four recur constantly. Cherry-picked splits: a statistic filtered until it flatters someone — “since 2024, in away matches, batting second” — is usually a sample of four innings wearing a suit. Level mixing:age-group numbers quoted next to international numbers as though the bowling were comparable. Recency: two big scores producing a permanent reputation. And outcome bias:judging a shot or a selection by whether it happened to work rather than whether it was the right call given the situation.
All four appear heavily around a young player having a breakout run, which is why our Vaibhav Suryavanshi guide and our young T20 batting core guide deliberately describe roles and shapes rather than freezing figures into the page.
- Balls are the scarce resource in T20 — that single idea explains most of the metrics.
- Role first, number second. A finisher and an anchor are not comparable on strike rate.
- Sample size is context, not a footnote.
