MELBOURNE, Australia (AP) — Coco Gauff had a little difficulty adjusting to the sun at one end of Rod Laver Arena and dropped an early service game but quickly settled into a rhythm to start her Australian Open a 6-3, 6-3 win Monday over 2020 champion Sofia Kenin.

MELBOURNE, Australia — There’s a young woman who looks a lot like Coco Gauff at Melbourne Park for the Australian Open. She has the same fiery, competitive eyes, the same tendency to break out in a giggle in the middle of a sentence and the same number of titles.

The No. 3 seed Gauff committed at least one double fault in seven of her nine service games, yet was only broken once in a meeting of the two most recent American major champions.
