Sydney: Young local Cameron Davis upstaged Jordan Spieth and Jason Day by shooting an eight-under-par 63 in benign morning conditions for a two-shot lead after the first round of the Australian Open on Thursday.
Day, playing his home Open for the first time since 2013, also had an early start and carded a five-under 66 for a share of third, but defending champion Spieth struggled to a one-under 70 in the afternoon wind.
Davis, 22, could hardly have made a better start to the day under bright blue skies at The Australian Golf Course with six birdies in his first seven holes, including a chip-in at the seventh.
