Vienna Open Kicks Off with Khachanov-Griekspoor Showdown as Headline Act

Vienna, Austria – October 21, 2025 – The Erste Bank Open in Vienna commenced on Monday with a high-stakes clash between fifth-seeded Karen Khachanov and Tallon Griekspoor drawing significant attention. The tournament, an ATP 500 event held at the Wiener Stadthalle, promises a week of intense competition with a stacked field of ATP Tour stars.

Khachanov, currently ranked world No. 10 and last year’s Vienna Open runner-up, entered the match against Griekspoor aiming to reverse a recent slump in form. After a strong summer highlighted by quarterfinal appearances in multiple tournaments and a final in Toronto, the Russian player suffered an early exit at the Almaty Open, marking his fourth consecutive loss since the US Open.

Standing in his way was Tallon Griekspoor, the world No. 27 from the Netherlands. While Griekspoor secured a title in Mallorca and reached the final in Marrakech earlier this year, his hard-court record stands at 13-14 this season, and his recent form has been inconsistent. He lost in a tight three-setter at the Stockholm Open prior to Vienna.

The match held added intrigue due to a previous encounter in Rotterdam, where Griekspoor defeated Khachanov in three sets. Despite this head-to-head advantage, Khachanov was considered the betting favorite. Sportsbooks gave Khachanov a 66.7% implied probability of winning.

Khachanov’s strengths lie in his solid service game, winning 81.7% of service games on hard courts this season. Griekspoor’s return game, though slightly less impressive, could prove crucial if he can capitalize on any vulnerabilities in Khachanov’s confidence. Griekspoor has won 19.8% of return games this season, which is slightly less impressive than Khachanov.

The opening day also featured Alex de Minaur, Alexander Bublik, Luciano Darderi, Aleksandar Kovacevic, and Matteo Arnaldi.

Both Khachanov and Griekspoor are seeking to gain valuable ranking points and momentum as the season nears its conclusion. Griekspoor has been confident coming into the match with the quote, “I know I can beat him—I’ve done it before. It’s all about bringing my best tennis when it matters.” The winner will advance to the Round of 16.
