WTA roundup: Clara Tauson upsets Diana Shnaider in Bad Homburg

June 23 – Clara Tauson needed less than two hours to record the biggest upset of first-round play at the Bad Homburg Open on Monday in Bad Homburg, ​Germany.

The 25th-ranked Tauson, who hails from Denmark, defeated Russian seventh seed ‌Diana Shnaider 6-4, 6-4 in an hour and 45 minutes, converting four of 10 break points and scoring six aces to Shnaider’s two. The victory snapped a seven-match losing streak ​for Tauson, whose last victory came in March at the BNP Paribas ​Open.

Shnaider, who won the Bad Homburg title in 2024, has lost ⁠back-to-back first-round matches on grass after Nikola Bartunkova of the Czech Republic knocked ​her out of the Berlin Tennis Open.

An ankle injury forced Iva Jovic to ​withdraw from her scheduled match against China’s Xinyu Wang. Mexico’s Renata Zarazua took Jovic’s spot in the match, which Wang won 6-1, 6-2.

Japanese sixth seed Naomi Osaka rolled past Poland’s Magdalena ​Frech 6-4, 6-1 in a match that was suspended on Sunday because ​of rain. Osaka, winner of four Grand Slam titles, won 60% (21 of 35) of her second-serve ‌points ⁠to Frech’s 21.4% (6 of 28).

Russia’s Anna Kalinskaya, China’s Qinwen Zheng, Romania’s Irina-Camelia Begu and Belgium’s Elise Mertens also advanced Monday.

Colombia’s Emiliana Arango took advantage of a last-minute opportunity when she filled in for Switzerland’s Viktorija Golubic, who withdrew with an ⁠injury. Arango, ​ranked No. 101, defeated Australia’s Maya Joint 7-6 (2), ​6-4.
