NEW YORK, United States—Danish fourth seed Caroline Wozniacki was ousted from the US Open on Thursday by 149th-ranked Czech Petra Cetkovska, leaving only three of the top-10 women in the event.
Cetkovska outlasted Wozniacki 6-4, 5-7, 7-6 (7/1) in a night match at Arthur Ashe Stadium to book a third-round match against Italian 26th seed Flavia Pennetta.
With the departure of former world number one Wozniacki, the US Open runner-up in 2009 and last year, the only top-10 seeds remaining in the year’s final Grand Slam tournament from the original draw are top-ranked Serena Williams, Romanian second seed Simona Halep and Czech fifth seed Petra Kvitova.
