Ashes 2023: Ricky Ponting alleges discrepancy in ball-change, demands investigation

Ricky Ponting told Sky Sports. Usman Khawaja and David Warner were playing well against the old Duke's ball as it was not swinging much. Against the new ball, the Australian players managed to survive for the day as the rain interrupted Day 4 and on the final day when the ball was still new, England's bowlers were more successful dismissing both Usman Khwaja and David Warner in quick succession.

"As soon as they changed that ball, I knew straight away that ball was very different. I went up to (umpire Kumar Dharmasena) and asked, 'How old is this ball? It feels like it's eight overs old.' You could see the writing on both sides, and it hit my bat so hard. I've opened the batting in every single innings this Ashes series, and I haven't felt a ball hit my bat as hard as that ball.

I said to the boys coming in, 'Be careful, this new ball is going to be tricky,'" Usman Khawaja told Channel 9 after the match. "Some things you can't control in this game, and it's disappointing for us because it felt like we had a real stranglehold on that game. That ball was at 90 overs and it was still hooping around corners and the keeper's taking it above his head.
