Aryna Sabalenka clashed with Rebeka Masarova in the opening-round of the 2025 Berlin Open. The 3-time Grand Slam winner was leading 6-2 when her opponent approached the umpire complaining of dim natural light and slippery grass as the dew built up.

Sabalenka was unhappy at the decision and both player had a discussion with the supervisor at the net.

At the end of their discussion Sabalenka let out a laugh in mock disbelief.

"So you're stopping the match because she said on that side it's slippery? I just played two games on that side," she said [at 1:15].

However, the supervisor stood his ground and asked the match to be suspended. The crowd made their feeling known by booing the chair umpire as he made the announcement. A visibly exasperated Sabalenka calmly packed her kit and eventually walked out of the Steffi Graf stadium with her opponent.

The match will resume on Thursday, June 19. Meanwhile Paula Badosa, Ons Jabeur and Liudmila Samsonova have secured a spot in the quarterfinals of the 2025 Berlin Open.
