FEW would be so bold as to go bald when the world is watching. But that's what doubles partners Croat Goran Ivanisevic and Italian Andrea Gaudenzi did at the Marlboro Championships at Victoria Park yesterday. The duo spent $400 each on skinhead cuts at the Marriott Hotel, but the reason will remain a secret. Law student Gaudenzi would reveal only that they had had a bet six months ago in Rome that if a certain event happened they would shave their heads. 'It has happened and we got a cut. But we cannot tell anyone. Not ever. Not Goran's coach, not my coach, not even my mother knows. 'I can tell you it has nothing to do with football and Vialli [the popular shaven-headed Italian soccer player]. Nobody will ever know.' 'My mother will kill me when she sees me,' said Ivanisevic. The pair wore bandanas for their match, revealing their baldness only after their three-set doubles defeat to India's Mahesh Bhupathi and Australian Mark Philippoussis. Interrogators tried every trick to persuade the pair to shed some light on the secret, but they chimed: 'We're not saying.' Gaudenzi said he felt a bit miffed at having to pay for being shorn. 'You lose all your hair and then you have to pay as well,' he said. 'I asked for a discount because I took the razor myself and helped her cut it. But I didn't get one.' One thing the haircuts did do was produce a Samson-like loss of strength - the pair were beaten by Philippoussis and Bhupathi 7-5, 2-6, 7-6 (7-2).
