Lindsay Davenport has revealed her excitement about the future of Madison Keys as the American teenager continues to impress at the Australian Open.
Davenport, a three-time Grand Slam winner, started working with Keys in October, and she claims that the 19-year-old has the potential to continue dominating opponents with her power after coming from behind to beat Casey Dellacqua in the second round of the Australian Open on Thursday.
"It sounds weird but I hadn't seen her that much, even though I cover tennis on TV, because she's not always on the main show courts," Davenport is quoted as saying by The Telegraph.
"So when I first hit with her the last few days of October, it was like, 'Oh my god, this is huge', and I played against people whose shots were considered heavy at the time, Venus [Williams] or Maria [Sharapova] or Serena [Williams].
"So I'm finding myself playing with someone who's only 19, who has these amazing weapons, who is pretty technically sound. What's holding her back? Maybe mentally how she approaches matches, or how she plays the bigger points, and she could do with some extra margin on some of her shots. But I feel everything she can improve on is coachable."
Keys will meet Petra Kvitova in the fourth round on Saturday.
