Here are six greats of the game whose batting averages took a hit during the final years of their Test careers. In November 2009, Jayawardene’s career average had gone up to 55, but he averaged less than 40 in his last 40 Tests. At the start of 2016, half a decade into Warner’s Test career, his average stood at 51.34, having slammed ten Test centuries in the previous two years.
