The VANDA Pharmaceuticals Berlin Tennis Open, a WTA 500 grass court event, moved into the round of 16 on Tuesday with a mix of seeded players advancing and some notable results.
Eva Lys defeated Magdalena Frech 7-6(5), 6-3. Linda Noskova beat qualifier Renata Zarazua 6-1, 6-4. Madison Keys topped Wang Xinyu 7-6(4), 6-1. These wins kept several established names in contention at the Steffi Graf Stadion.
Karolina Muchova also advanced comfortably, beating Zhang Shuai 6-1, 6-3. She is scheduled to team up with Serena Williams in doubles later in the day against Giuliana Olmos and Erin Routliffe. Williams is making her competitive return in the doubles draw.
The tournament, which runs through June 21, serves as an important tune up for Wimbledon on the grass surface. Top players including Aryna Sabalenka, Elena Rybakina, and Coco Gauff remain in the singles field, though some withdrawals earlier in the week affected the original lineup.
Earlier in the event, wildcard Nikola Bartunkova produced an upset by knocking out ninth seed Diana Shnaider in three sets. The Berlin Open continues with more round of 16 action scheduled throughout the day.
