Not so much a trick as his actual training method when he was a youngster. According to the Sydney Morning Herald, Clarke is featured in the latest TV commercial in Australia doing it. If anyone has a video, or link, do share.
FIRST it was The Don. Now it is Pup’s turn. Michael Clarke has emulated Donald Bradman’s golf-ball-and-stump practice technique in Cricket Australia’s new television advertising campaign promoting the 2007-08 season.
In the first television ad of the “Hungry for it” campaign, Clarke replicates the famous footage of The Don sharpening his skills by throwing a golf ball at the base of a water tank and batting it back and forth with a stump – just as he did as a child in Bowral. Cricket Australia said the campaign focused on the new breed of stars who were steering Australian cricket into the future.
Clarke, who still uses the technique to fine-tune his batting, said he was honoured to be featured in the advertisement.
