It's not recorded just how well Rinky Hijikata played in practice on the eve of his first Wimbledon second-round match against American big gun Ben Shelton - but if the Australian was rubbish, he will probably have been whooping with delight.
The Sydneysider says it's become a bit of a habit with him to practise dismally one day and then produce an impressive performance the next, particularly in big matches.
Indeed, before his first-round match against David Goffin on Tuesday, he played a set-and-a-half in practice against his fellow Australian, the country's No.1 Alex de Minaur, and got filleted 6-0 3-0.
