Aryna Sabalenka vs. Cristina Bucsa Preview, Prediction and Betting Odds for US Open 2025 Round of 16

Sabalenka is searching for her fourth Grand Slam title.

World No. 1 Aryna Sabalenka resumes her title defense against Cristina Bucca in Round-4 of the 2025 US Open. The top seed is into her fifth consecutive US Open second week, after dominating all three of her previous rounds. On the contrary, this is the deepest Grand Slam run of Cristina Bucsa’s career. The Spaniard has caused a run of upsets in her journey up until now. Will that continue? Let’s find out, using the most accurate odds from BetMGM.

Aryna Sabalenka vs Cristina Bucsa Match Preview

After a mediocre set of events, Aryna Sabalenka is close to her usual best at the US Open so far. The Belarusian’s serve, in particular, has become a sight to behold. Although she hasn’t blown away her opponents in typical Sabalenka fashion, the 27-year-old has come through some competitive battles without dropping a set. Currently on a 10-match unbeaten run at Flushing Meadows, Sabalenka is naturally heading into this match as a giant favorite.

This is where Spain’s Cristina Bucsa comes into picture. If Sabalenka is a giant favourite, then Cristina Bucsa has shown herself to be a giant slayer in this tournament. With some high quality wins over the likes of Alexandra Eala and Elise Mertens, the World No. 95 has emerged as one of the breakout stars of the competition. One of her key strengths lies in her style – she hits a flat ball with variable pace.

Aryna Sabalenka vs Cristina Bucsa US Open 2025 Prediction

If Cristina Bucsa can frustrate Aryna Sabalenka early on with her flat playing style, the top seed could give her some openings. However, the World No. 1 is a master at adapting to the evening conditions, which will provide a neutral playing field. Once she settles into the clash, the venom on her groundstrokes are likely to be too much for Bucsa to handle.

Prediction: Aryna Sabalenka in straight sets.
