Why aren't T20 teams scoring bigger more often?

If more sides approached T20 less like traditional cricket forms and embraced all-out hitting without worrying about wickets, they would end up consistently pushing the envelope

Jarrod Kimber16-May-2019Andre Russell’s left foot pointing to midwicket, his right knee bent, and his arms swinging through a ball that’s about to be called a wide is not what you think of as a traditional cricket shot. Test batting has actually slowed down in recent years, meaning T20 cricket has never been less like it. The runs-per-over figure in the last three years for Tests is 3.2, for ODIs 5.3, and in all T20s it is 8.2.T20 has lit a fire under attacking batting, and for someone who believes Test batting is proper cricket, it’s hard to look at T20 hitting and not think it’s crazy. We’ve not only perfected the cow-corner hoick but the inside-out hockey-slap, the back-of-point slice, and a host of other shots where someone will lose their Adam’s apple. Players now understand how to hit the ball hard.But the actual gains in run rates across formats are pretty low. Players aren’t adding an extra run a year in T20, and ODI cricket hasn’t become as much like T20 as some would think. The highest run rate in ODIs over a year was in 2015 – 5.5 per over; and that included extras. Viv Richards scored at 5.4. In ODIs last year the economy rate was 5.3 (mocking the whole “300 is par” notion), though it had risen from 5.12 in 2009. Even if you look at the lowest yearly run rate in the last decade, 5.05 in 2012, against the highest, in 2015, it’s only an 8% rise.ALSO READ: Types of T20 teams: the six-hitting sideThe run rate in T20 has grown slightly more quickly. In the last decade, the lowest run rate was 7.48, in 2013; last year it was 8.4, which is an 11% rise. Unlike a good T20 innings, it has been steady rather than spectacular.And that is because T20 cricket is still anchored in what we might call “normal cricket”. In 2018 the T20 batting average for all batsmen was, at 25.06, the highest it has ever been, suggesting that batsmen are putting more value on their wickets now than in previous years. They might hit a lot of sixes, and they might get quicker with their scoring, but they still play T20 like normal cricket, just with more urgency. It has not truly become a sport in its own right just yet, although it is well on its way.In computing and science, people talk about theoretical limits. In nature, the theoretical limit to how fast something can travel appears to be the speed of light (about 300,000km/s). The fastest observed human is Usain Bolt, clocked at 44.72kph. So there appear to be natural limits depending on mass, physiology and other factors. For T20 cricket we have a theoretical limit of how fast batsmen could score if they did not worry about losing wickets – the scoring rate off free hits.Since 2008, the scoring rate off free hits stands at 12.54 (runs per over); so batsmen can’t score at much faster than two runs a ball. As T20 currently stands, 12.5 is our theoretical limit, which translates to an innings score of 250.At the moment the rise of the run rate off normal deliveries is fairly in sync with the run rate off free hits. A couple of years one has increased while the other has fallen – or vice versa – but overall they are rising fairly equally. (The free-hit run rate has swung more but that is mainly because there are so few free hits every year, amounting to a fraction of a percentage point of all runs scored.)
