The affectionate sobriquet is just about the only piece of puffery applied to Spanish tennis phenom Carlos Alcaraz. And Carlitos might be the only obstacle capable of stopping Novak Djokovic in his history-making tracks at Wimbledon. He recently fired a warning to challengers by posting a clip of himself on social media, nibbling on the grass at Wimbledon. The last time, at Roland Garros, Djokovic handed Alcaraz his hat with a 6-3, 5-7, 6-1, 6-1 semifinals ouster, though Alcaraz had been struck with full-body cramps. And there’s the swashbuckling Aussie Nick Kyrgios, who made his maiden major final at Wimbledon a year ago, losing to Djokovic.
