What's included

Professional men's T20 with six-ball overs — the IPL, Big Bash, PSL, Vitality Blast, Caribbean Premier League, T20 internationals and many more.

Tests, one-day cricket and The Hundred are deliberately excluded rather than blended in: a Test strike rate near 50 and a T20 strike rate near 140 mean different things, and “death overs” only has meaning in a 20-over innings. The Hundred uses five-ball overs, so its rates aren't comparable either. Women's T20 needs its own baselines and will get its own section.

Around a fifth of deliveries are bowled by players with no published bowling style. Those balls are left out of the bowling-type splits rather than guessed, so a batter's total balls faced will exceed the sum of their type rows.

How the splits are calculated

• Strike rate is runs off the bat per 100 balls faced. Wides are not counted as balls faced; no-balls are.
• Run-outs are not credited to the bowler, nor are retirements or obstruction.
• Super overs are excluded — a handful of extreme-tempo overs would distort every aggregate.
• Phase of innings uses each innings' stated powerplay bounds rather than fixed over numbers, so rain-shortened matches stay correct. Death is the last four scheduled overs.
• A split needs at least 30 balls to appear. Below that it is noise, not a finding.
• Shading compares a batter to the league average against that same bowling type — comparing to a global average would only re-measure that spin is harder to score off.
