Kallis appears to be the only anomaly in Mangan’s study
According to a study conducted by professor John Mangan, all of the world’s greatest batsmen, whether they be past or present, hit their peak at 29.875 years.
The study was conducted after veteran Australia batsman Ricky Ponting horrendous series against South Africa, during which he announced his retirement from international cricket.
Mangan’s thesis, titled ‘Ageing and Test Cricket Averages; A Statistical Note’, provided an insight into the batting averages of many of the world’s greatest batsmen and showed how their numbers started to decline as they continued to play into their late 30s.
The paper, which included cricketers such as Ponting, Michael Hussey, Sir Donald Bradman, Sachin Tendulkar and Brian Lara revealed that all these legendary batsmens’ averages peaked at the age of 29.875.
Speaking about Ponting, Mangan noted that since the 2006-2007 Ashes series, where the former Australian captain averaged 59.99 with that bat, he has been involved in 59 more Test matches and accumulated 4,107 runs at an average of 41.07.
However, Mangan revealed that there was one anomaly with his data as veteran South Africa all-rounder Jacques Kallis had an outstanding record throughout his 30s, while all the other batsmen started to cool down, and added that he may even be getting better at the age of 37.
“I can’t imagine anybody except Kallis has got better at 35 or 36,” Mangan said.
