NEW YORK (AP) Wimbledon champion Petra Kvitova was stunned in the third round of the U.S. Open by a scrambling, moon-balling qualifier ranked No. 145.
Aleksandra Krunic, a 21-year-old Serb who until this week had not taken even a set from a player in the top 30, crumpled to the court in celebration and shock Saturday when she pulled off the 6-4, 6-4 upset of the third-seeded Czech.
"Of course, I didn't expect to win," said Krunic, the second qualifier to pull off such a shocker after 121st-ranked Mirjana Lucic-Baroni beat No. 2-seeded Simona Halep on Friday.
