Both the men's and women's top-seeded players came up a match short of reaching the semifinals at the Fifth Third Bank Tennis Championships on Friday at the University of Kentucky's Hilary J. Boone Tennis Complex.
All four men's quarterfinal matches went to three sets, including Australia's James Duckworth defeating top-seeded Illya Marchenko of Ukraine 6-1, 5-7, 6-4.
Duckworth, seeded sixth, opened the match with what he called "one of the best sets I have played all year."
He said he had to regain his focus and calm after the second set. Despite his cool demeanor throughout the match, he let loose on the changeover after losing the second set, hitting a tennis ball into orbit and dropkicking his racket. He recovered quickly, though.
Never miss a local story.
"I really have to work to stay calm, and it's paid dividends," Duckworth said. "Last year I would have capitulated after the second set."
Duckworth will face American Bradley Klahn in the semifinals. Klahn defeated the lone qualifier left, American Tennys Sandgren, 6-4, 4-6, 6-3.
In the lower half of the draw, the only wild-card player left in the tournament, Filip Peliwo, upset eighth-seeded Malek Jaziri of Tunisia. The 19-year-old Canadian lost the first set 4-6, before going on to win the next two, 7-5, 6-2.
Peliwo will play Great Britain's James Ward in the semis.
On the women's side, 30-year-old Julie Coin of France defeated top-seeded Misaki Doi of Japan in straight sets 6-4, 6-3.
American Shelby Rogers defeated Catalina Castano 6-4, 6-4, on Friday, keeping the South Carolina native in contention for a U.S. Open wild card, which she will receive if she wins the tournament.
"The competition was a little rough today, up and down, but I got the win and that's what matters," Rogers said. "I'm excited to get through and still be in contention for the wild card."
