Former Australia captain Ricky Ponting has called for the ball change which occurred during Australia's second innings in the ongoing fifth Ashes Test at The Oval to be investigated, a move which he termed as a ‘huge blunder’. After Mark Wood hit Usman Khawaja on the helmet with a bouncer on the first delivery of the 37th over, umpires Joel Wilson and Kumar Dharmasena changed the ball, citing that it had gone out of shape. But the replacement ball looked newer than the previous ball, as Khawaja, David Warner and Marnus Labuschagne were dismissed in quick succession in Australia’s chase of 384.
