Coco Gauff eased into the second round of the Australian Open on Monday, beating unseeded Anna Karolina Schmiedlova 6-3, 6-0 in a one-sided affair on centre court. The American, bidding to become the first woman since Naomi Osaka in 2018-19 to win the US Open and Australian Open back-to-back, made a nervy start. But she still had too much for her struggling Slovakian opponent, who failed to win any of her seven service games. Fourth seed Gauff broke Schmiedlova, ranked 68, four times in the opening set with two holds proving decisive for the 19-year-old, who defended her Auckland title earlier this month.
