WIMBLEDON, England (AP) Ash Barty's winning streak is over, and so are her chances of winning a second straight Glam Slam title.
The top-ranked Australian had won 15 matches in a row, including the French Open title, but she lost to Alison Riske 3-6, 6-2, 6-3 at Wimbledon on Monday, giving the unseeded American a spot in the quarterfinals of a major tournament for the first time.
''I haven't been starting out fantastic in all my matches, but I knew I had the confidence that if I could manage my service games I was going to get looks on her serve,'' said Riske, whose best previous showing was reaching the third round at Wimbledon and the fourth round at the 2013 U.
