MELBOURNE, Australia (AP) Madison Keys advanced to her first Grand Slam quarterfinal with a 6-2, 6-4 win over good friend and fellow American Madison Brengle in a battle of the Madisons at the Australian Open on Monday.
The 19-year-old Keys dominated the match, hitting 38 winners to just three for Brengle and breaking her opponent four times.
It was the first time since Jennifer Capriati played Amy Frazier at the 2002 U.S. Open that two Americans besides the Williams sisters played each other this late in a Grand Slam.
Keys said after the match, ''You know it's always hard just even being in this situation, then on top of it playing a friend.''
Keys, who had never previously been beyond the third round of a major, is now coached by three-time major winner Lindsay Davenport.
