Madison Keys, who lost to seventh-seeded Samantha Stosur in the second round of Indian Wells, says she understood what she need to do to improve on the plane back from Australia. The 18-year-old was unable to beat Angelique Kerber in a tight third-round match.

“Moving better serving better and making better in tight situations,” said Keys, who has been focusing on taking deep breaths in between points. “I feel like when the nerves come I start making errors. I have a tendency to go faster and faster so I’m working on trying to slow down to keep my head clear so I can think.”
