Bowlers made hay, Root rose, Kohli fell, and debutants had a ball

All the stats highlights from 2021, when ball dominated bat in Tests, Pakistan called the shots in T20Is, and ODIs faded into insignificance

S Rajesh04-Jan-2022A tough year for battersIn the last 40 years, only once has the average runs-per-wicket figrure in Tests been lower than it was in 2021, when 28.78 were scored per dismissal. This one stat confirms that 2021 was another year when bowlers held sway, and batting was generally a difficult task.The only year in this period when bowlers dominated even more was 2018, when each wicket cost 27.58 runs. In fact, these are two of four years in the last 40 when the average has slipped below 30; the other two were 2000 and 1988.ESPNcricinfo LtdIf you look at more metrics, they all tell a tale of bowlers dominating and batters struggling: 17 team totals of 400-plus were scored in 44 Tests, a rate of one every 2.59 matches. Only thrice in the last 40 years have they been more scarce – in 2018 (2.67), 1992 (2.60) and 1988 (3.00). The story is similar in terms of innings per century: 28.53 in 2021; there have been just two instances of longer waits between hundreds, in 2020 (29.54) and 1988 (34.44).Two-hundred-and-fifty-three 50-plus scores were made in Tests in 2021, of which only 58 were converted into hundreds. That is a conversion rate of 22.92%, which indicates that batting wasn’t easy even after the batters got in. The rate was 20.63 last year, but that was a truncated year, which featured about half the number of matches as in a regular year. Before that, you would have to go back to 1995 to find a year with a poorer conversion rate of fifties to hundreds.ESPNcricinfo LtdUnlike in several other years, 2021 was one in which both fast bowlers and spinners flourished. The pacers conceded 27.14 runs per wicket – an average next only to those of 2018 and 2019 among the last 40 years – while spinners averaged 30.52, second only to 2018 in this period.Of the 24 bowlers who took 20 or more Test wickets in 2021, 20 averaged lower than 30, and eight under 20 runs per wicket. The 11 bowlers who picked up 30 or more wickets in the year included six fast bowlers and five spinners. At the top of the pile was R Ashwin, who had a phenomenal year, picking up 54 wickets at 16.64. Never has a spinner taken 50-plus wickets in a calendar year at a better average: the best before 2021 was Muthiah Muralidaran, who took 90 at 16.90. In fact, Ashwin is in the top five for all bowlers with a 50-wicket cut-off, and features twice in the top eight.
