Tennis Australia CEO Craig Tiley has a grand slam of a plan to turn the Australian Open into a huge event – he says “not just in the southern hemisphere, or in January, but the biggest sporting event in the world.” It would involve increasing the prize money, extending its duration and enhancing the spectator experience through technology. And like Saudi money is changing golf, Tiley says tennis has to be open to it to make the circuit what it could be. Talk of a ‘premium tour’ has been around for ages, and Tiley is at the forefront of the push for change. But for the next fortnight, his focus will be on a smooth Australian Open. Today, the big game to look out for is Alex de Minaur’s match against Milos Raonic. C’mon Aussie… Naomi Osaka is also making her big return against Caroline Garcia later tonight.
