Switzerland's Belinda Bencic, the 17-year-old protégé of Grand Slam champ Martina Hingis, beat No. 9 seed Jelena Jankovic Sunday night to reach the U.S. Open quarterfinals. She overcame a stuttering start to defeat Jankovic, 7-6 (6), 6-3.
Jankovic had a chance to serve out the first set, but Bencic broke her twice, then took the tiebreaker. Bencic seemed to get stronger as the match -- 2 hours and 2 minutes for two sets -- wore on before a thin but enthusiastic crowd at Arthur Ashe Stadium. "It was a dream to always play on this court since I was a child," Bencic said in an on-court interview. "Everything is so huge and I had to get used to it."
Bencic, who eliminated No. 7 seed Angelique Kerber in the third round, is the youngest player remaining in the main draw.
