What's luck got to do with it: a control review of the World Cup

Why England were a pale shadow of their 2019 selves, and how Australia’s power-over-technique template paid off

Kartikeya Date14-Dec-2023Travis Head faced Jasprit Bumrah on the fourth ball of the third over in the second innings of the 2023 ODI World Cup final. Bumrah was bowling around the wicket to him. The delivery was aimed at the off stump from wide of the crease and moved away. Head, according to the ball-by-ball commentary on this site, “stays leg side of the ball and almost nicks it off”. Head was beaten on the inside or outside edge in this manner on the seventh, ninth, tenth, 18th, 19th, 22nd, 26th, 28th, 29th and 30th balls he faced. This included him inside-edging past leg stump, playing and missing outside off stump, and being beaten on the inside edge as he fell over. Before scoring 25, Head was beaten multiple times in nearly every single one of the ways it is possible for a batter to be beaten by a bowler in cricket. He played a false shot to ten of his first 30 balls.He went on to score a brilliant 137 off 120 balls, playing only ten false shots in his last 90 balls. When India batted earlier that day, Rohit Sharma played five false shots in his first 30 balls. He played his sixth to his 31st and was dismissed for 47. A few balls later, Shreyas Iyer stayed leg side of the ball and nicked off against Pat Cummins instead of merely playing and missing.Head’s survival and Iyer’s dismissal were not by the batter’s design. No player’s survival of a false shot is by design. It is a matter of that dreaded thing – luck. In cricket, luck is the accumulation of favourable outcomes for a set of actions to an extent that is significantly different from the average expected outcomes for that set of actions. It is only by accounting for luck that distinctions in skills can be located.Related

In addition to the three traditional measurements in cricket – runs, balls and wickets – ESPNcricinfo’s control measurement records whether or not the batter was in control of the delivery. Control makes three measurements possible:1. The frequency of a false shot (balls per false shot)
2. How often a false shot results in a dismissal (false shots per dismissal)
3. Runs per false shotThese measurements help us locate luck and skill (or efficiency). For instance, if Head had played only four false shots in his first 30 balls, to dismiss him, India would have needed one in four false shots to go their way. As it happened, they needed only one in ten to go their way in those first 30 balls. That is to say, they forced a false shot every third ball on average. In the remaining 90 balls, they created comparatively little jeopardy. In that early part of the innings, Head was lucky. But after his first 25 or so runs, India would have needed to be lucky to dismiss him.The control measurement is the hinge of the cricketing contest. It helps to measure how much jeopardy the bowlers create, how much risk the batter has assumed, how lucky the bowlers are, and how efficient the batter is. Before we use it to understand the 2023 World Cup and how its patterns were different from those of the 2019 tournament, it is worth reflecting on the patterns of the control measurement.A survey of the control record since January 1, 2016 shows that a dismissal occurs every 10.1 false shots in Tests, 7.7 false shots in ODIs, and 5.6 false shots in T20Is. A false shot occurs once every 5.6 balls in Tests, once every 4.8 balls in ODIs, and once every 3.3 balls in T20Is. Quicker scoring involves more frequent risks and also bigger risks (the average false shot is more likely to result in a dismissal in a T20 than in a Test). Within each format, the evidence suggests three things.First, a batter’s capacity to avoid false shots (Balls Per False Shot) and to survive them (False Shots Per Dismissal) depends on skill. The table below gives the rates for each by batting position in Tests and ODIs.
