Iga Świątek entered the 2025 U.S. Open with a strong case as one of the women most likely to win the title. She was the No. 2 seed, had already reached the Australian Open and French Open semifinals that year, and had just won Wimbledon for the first time.
New York did not end with another trophy. Świątek reached the quarterfinals before Amanda Anisimova beat her 6–4, 6–3. That result matters because Anisimova had lost the Wimbledon final to Świątek only weeks earlier. The U.S. Open became a reminder that even a dominant result in one major does not freeze the matchup in place.
Świątek Came to New York as the No. 2 Seed
Świątek’s 2025 season had already been unusually complete by the time she arrived in Flushing Meadows. She was known first for clay-court dominance, but the Wimbledon title changed the conversation about how broadly her game could travel across surfaces.
She also entered the U.S. Open as the 2022 champion, so New York was not unfamiliar territory. The question was whether the Wimbledon momentum could carry through another major only a few weeks later.
Her Early Rounds Were Mostly Efficient
Świątek moved through the draw with mostly controlled performances. She beat Emiliana Arango 6–1, 6–2 in the first round, Suzan Lamens 6–1, 4–6, 6–4 in the second, Anna Kalinskaya 7–6, 6–4 in the third, and Ekaterina Alexandrova 6–3, 6–1 in the fourth round.
The Lamens match was the obvious warning that the run would not be effortless, but by the quarterfinal stage Świątek had dropped only one set in four matches.
The official U.S. Open quarterfinal preview noted that she had spent just over six hours on court through the first four rounds. That put her in good physical position for the second week.
The Quarterfinal Was a Wimbledon Rematch
The quarterfinal against Amanda Anisimova carried an obvious storyline. At Wimbledon, Świątek had beaten Anisimova decisively in the final. In New York, Anisimova had a chance to answer on a faster hard court.
She did. Anisimova won 6–4, 6–3 and reached the U.S. Open semifinals for the first time.
That reversal is one reason tennis matchup analysis has to be cautious. A previous score can tell us what happened under one set of conditions. It does not guarantee the same pattern when the surface, confidence, serving, return position, wind, timing, and tactical choices change.
Anisimova Took Time Away From Her
Anisimova’s best tennis is built around clean, early ball striking. She can take the ball before an opponent has fully recovered and redirect pace without needing long preparation.
That matters against Świątek because Świątek is at her best when she can use heavy spin, depth, and movement to push an opponent into increasingly uncomfortable positions. Taking the ball early can shorten that process.
At the U.S. Open, Anisimova did enough of that work to keep Świątek from settling into the kind of repeated pressure that had broken the Wimbledon final open.
Hard Courts Reward Different Margins
Świątek’s forehand is built around heavy topspin and aggressive court positioning. On clay, that shape can push opponents backward and create awkward contact points. Hard courts generally give the ball a cleaner, faster response, which can help flatter hitters step in sooner.
That does not make Świątek a poor hard-court player. A U.S. Open title already proves otherwise. It simply means the tactical balance changes.
Serving Still Shapes the Entire Point Pattern
Świątek’s serve is most useful when it starts the rally on her terms rather than trying to win every point outright. A well-placed first serve can open the next forehand or keep an aggressive returner from stepping too far inside the baseline. Recreational players working on the same patterns can practice with a basic Wilson Federer tennis racket rather than assuming better technique starts with expensive gear.
Against strong first-strike players, second serves become especially important. A short or predictable second serve can hand the opponent immediate control.
That is where athletic preparation and repeatable movement patterns matter over a long tournament. Our guide to what sports conditioning really means explains why conditioning is not simply “being fit.” It is being physically prepared for the exact demands the sport keeps repeating.
The Return Is One of Świątek’s Biggest Weapons
Świątek is one of the strongest returners in women’s tennis because she reads the serve quickly and can put pressure on second serves before a point develops normally.
That pressure can make an opponent feel as though every service game starts slightly uphill. But against a player striking confidently and protecting the first ball well, the return advantage becomes harder to turn into repeated breaks.
The Women’s Field Was Deeper Than One Favorite
The original article framed Świątek as the player who “set the pace” for the tournament. That was too narrow. Aryna Sabalenka entered as the top seed and ultimately won the championship. Anisimova reached the final. Naomi Osaka made another deep run. Jessica Pegula was also in the quarterfinal mix.
That depth is what made the event compelling. A major is not a ranking exercise where the highest-rated player automatically advances. Seven matches create seven chances for conditions and matchups to change the story.
The Ranking Story Was Real, but the Tournament Was Bigger
Świątek and Sabalenka were also competing inside a larger rankings story. Strong major results can swing thousands of points, especially when players are defending different results from the prior season.
But ranking scenarios can distract from what is happening match by match. Players do not win a quarterfinal because a spreadsheet says the No. 1 position is available. They still have to serve, return, move, recover, and make decisions under pressure.
Fitness Is More Than Surviving Long Matches
Świątek reached the quarterfinal without an enormous workload, which is usually an advantage. Still, Grand Slam fitness is not just total hours played.
Players deal with heat, humidity, late finishes, warm-ups, practice sessions, travel around the grounds, media duties, recovery work, and the mental effort of preparing for a new opponent every other day. The same basic recovery ideas apply outside elite tennis, and this practical guide to post-workout food and recovery gives everyday athletes a simple way to think about refueling.
Knowing the difference between normal training stress and a warning sign is part of staying available. Our article on listening to your body in sport covers that principle for everyday athletes even though the professional setting is far more demanding.
One Loss Did Not Rewrite the Season
A quarterfinal defeat at a major feels large because the tournament ends immediately. It can still sit inside an excellent season.
Świątek had already won Wimbledon in 2025 and had reached the semifinals at both the Australian Open and French Open. The U.S. Open quarterfinal made it four deep Grand Slam runs in the same year.
That is why “greatest” debates need context. Our guide to how GOAT arguments work in sports explains why one tournament, one surface, or one head-to-head result rarely settles a broader legacy question.
Anisimova’s Response Was Part of the Story Too
The quarterfinal should not be told only as something Świątek failed to do. Anisimova earned the result.
She had already reached the Wimbledon final that summer, then responded to one of the most painful losses imaginable by beating the same opponent at the next major. She eventually reached the U.S. Open final and finished 2025 as one of the season’s biggest comeback stories.
What the 2025 U.S. Open Actually Showed
The tournament did not prove that Świątek had lost her edge. It showed how small the margins become when the field is deep and an opponent finds the right conditions for her game.
Świątek arrived as a legitimate title contender, played efficiently through four rounds, and lost to an opponent who struck the ball cleanly enough to prevent her from controlling the baseline patterns.
That is a better lesson than the pre-tournament prediction that one player would simply “set the pace.” At a Grand Slam, the favorite brings the résumé. The draw decides how much of it survives the next two weeks.
