- Former world number one Ana Ivanovic became the second top 10 seed to suffer a shock early US Open exit when she was knocked out by Karolina Pliskova of the Czech Republic on Thursday.
Ivanovic, the eighth seed, lost 7-5, 6-4 to the 42nd-ranked Pliskova who has reached the third round at a major for the first time.
The Serb followed fourth-seeded Agnieszka Radwanska out of the tournament after the Pole had been beaten by Peng Shuai 24 hours earlier.
Ivanovic came into New York as a potential title contender having captured trophies at Auckland, Monterrey and Birmingham this year while returning to the top ten for the first time in five years.
But the former French Open champion was undone on Thursday by 29 unforced errors while facing 13 break points as she crashed to her earliest exit in New York in six years.
