Marketa Vondrousova's return to competitive tennis was short-lived.
The 18th-ranked player in the world and the No. 2 seed at the Palermo (Italy) Ladies Open, Vondrousova fell to unseeded Slovenian teen Kaja Juvan in the first round Tuesday, 1-6, 7-5, 6-4.
Also falling among seeded players was No. 5 German Elise Mertens, who lost to Belarusian Aliaksandra Sasnovich 6-4, 6-1.
Top-seeded Petra Martic of Croatia fared much better, breezing past Belgian Alison Van Uytvanck 6-0, 6-3, and fourth-seeded Anett Kontaveit of Estonia also advanced by beating Romanian Patricia Maria Tig 6-3, 6-3.
The 21-year-old Vondrousova won 63 percent of the points and broke Juvan three times in the first set. But the 19-year-old Juvan tightened up her Czech opponent after that, breaking Vondrousova six times while being broken four times across the final two sets, recording all three of the match's aces.
The clay-court win was Juvan's first against a top-20 opponent.
"She started off really well, and I was a little bit nervous," Juvan said in her post-match news conference.
"The conditions were pretty hard, but then in the second and third set I kind of calmed myself and I started playing much better," Juvan continued. "She wouldn't let me go easily, but that's tennis, and I just tried to do my best."
The men's ATP Tour, also idle since early March due to the coronavirus pandemic, isn't due to restart until the Western Southern Open begins in New York on Aug. 22. The event, normally held in Mason, Ohio, was moved to the site of the U.S. Open, which will follow at the USTA Billie Jean King National Tennis Center the following two weeks.
