Mark your calendars for a thrilling match at the 2025 US Open women's singles Round of 16, where World No. 2 Iga Swiatek will face off against the talented Ekaterina Alexandrova. This showdown is sure to be one for the books! Taking place in the iconic Louis Armstrong Stadium, this encounter is more than just a fourth-round clash—it is a duel of styles, resilience, and momentum.

The former WTA World No. 1 and current Wimbledon champion, Swiatek, has moments of untreated spark, though intermittent, and has not been as steady in New York as she could be. Not so in the case of Alexandrova, who seems to be enjoying one of the most stellar seasons of her career, as she slices through the early rounds of the tournament with brazen ease.

Iga Swiatek has displayed some of her customary tenacity, but she has not appeared invincible in New York.

Her third-round battle against Kalinskaya highlighted Swiatek’s vulnerability. She trailed 1-5 in the opening set and had to fend off multiple set points before clawing back to force a tiebreaker. Despite hitting 33 unforced errors and struggling with her first-serve percentage (43%), the Polish star found a way to win—an attribute of champions.

Swiatek’s transformation since the grass-court season has been remarkable. Winning Wimbledon boosted her confidence, and her aggressive style now translates more effectively to fast hard courts. Still, she knows her margin for error against Alexandrova is slim.

Alexandrova has been in blistering form at the US Open, sweeping past opponents with little resistance.

Her third-round demolition of Siegemund was a statement. Alexandrova hit 19 winners, committed only 2 double faults, and broke her opponent six times en route to a 57-29 point dominance. She has dropped just nine games across three matches—arguably the cleanest path to the Round of 16 in the women’s draw.

At 30 years old, Alexandrova is playing the most consistent tennis of her career. With her flat groundstrokes, sharp angles, and improved serve, she has become a genuine threat to top players.

Their matches have been extremely competitive, particularly on hard courts, where Swiatek's topspin-heavy strokes collide with Alexandrova's aggressive baseline game. In Miami, Alexandrova defeated Swiatek in straight sets the last time she faced the opponent.

Swiatek edges Alexandrova in return games and consistency, while Alexandrova holds an advantage in raw serving power.

With determination and aggression, take on the second serve from Swiatek.

Over 20.5 games: Expect a tight battle with at least one long set.

This match is closer than rankings suggest. Swiatek is the more accomplished player, but Alexandrova’s current form and aggressive style make her dangerous.

The Swiatek vs. Alexandrova showdown is a clash of styles: Swiatek’s controlled aggression and topspin-heavy play versus Alexandrova’s flat, first-strike tennis.

If Swiatek plays at her best, she should progress to the quarterfinals. But Alexandrova’s red-hot form suggests this won’t be straightforward. Expect momentum swings, a possible deciding set, and plenty of fireworks at Louis Armstrong Stadium.

• Betting Recommendation: Swiatek to win in three sets, over 20.5 games.

In the 2025 US Open Round of 16, there are interesting pairings, but none more so than Iga Swiatek vs. Ekaterina Alexandrova. Swiatek wants to expand her collection of Grand Slams. Alexandrova wants to nail her first major quarterfinal. The stakes are high.
