After losing to Ash Barty in the semifinals, Madison Keys decided to give her fellow American Danielle Collins a scouting report ahead of the Australian Open title match.
It won't be easy reading for Collins, who will try to prevent top-ranked Barty from becoming the first Australian woman in 44 years to win the Australian Open singles championship.
Barty goes into Saturday's final on a 10-match winning streak and having lost just 21 games in six matches without dropping a set. She has also won 81 of her past 82 service games.
Keys, who lost 6-1, 6-3 to Barty in the semis, isn't surprised by those statistics.
"You have a game plan in your head, but she's just executing everything so well," Keys said. "She's serving incredibly well, so you don't get any free points on that.
