Coco Gauff has made improvements to her serving and her forehand. And the strides in both of those areas are among the reasons she's considered one of the few women ready to challenge two-time defending champion Aryna Sabalenka for the title at the Australian Open.

Coco Gauff continued her recent winning streak with a 6-3, 6-3 victory over former Australian Open champion Sofia Kenin on Monday at Rod Laver Arena.
