Aryna Sabalenka did what top seeds are meant to do at the US Open, moving past Taylor Townsend 6-4, 6-3 on Arthur Ashe Stadium to reach the quarterfinals. The world No. 1 won 63 total points to Townsend’s 50 and turned the match into a return showcase. Despite landing fewer first serves, Sabalenka controlled the big exchanges and kept her error count down when it mattered.

Relentless returning set the tone

Sabalenka’s return was the match-decider. She won 38 points as the receiver compared to Townsend’s 21, a gap that powered seven breaks of serve. Against Townsend’s first delivery, Sabalenka collected 23 of 48 return points for 47 percent. She was even more effective against the second ball, taking 15 of 19 for a strong 78 percent. That pressure produced seven break points converted and tilted both sets her way.

Townsend’s serve had bite at times, highlighted by six aces, but the follow-up ball did not pay off often enough. She claimed just 12 of 33 first-serve return points against Sabalenka’s delivery and 9 of 13 on second-serve returns. Even when Townsend held, the weight of return games kept coming. Sabalenka also posted the match’s longest surge of points in a row at eight, an indicator of the sustained pressure on return. In a straight-sets match without tiebreaks, that much success on the return side usually writes the story.

Serve numbers in context at Arthur Ashe

The serve battle was more nuanced than the final score suggests. Sabalenka landed only 46 percent of first serves overall, well below Townsend’s 72 percent. Yet when the first ball did land, the top seed won 64 percent of those points, while Townsend managed 52 percent. Second-serve points were tricky for both, though Sabalenka still came out ahead 31 percent to 21 percent on those exchanges. It meant Sabalenka’s serve games were about surviving pressure, not stacking aces.

There is a quirky stat here: Sabalenka actually won fewer service points than Townsend, 25 to 29. The difference was that she converted those points in the right moments and protected five of her nine service games. Townsend held only three service games out of 10 as she faced 14 break points and saved seven of them. Double faults were close at 2 for Sabalenka and 3 for Townsend, with aces favoring the American 6 to 2. Stack it together and the story is clear. Townsend’s higher first-serve percentage did not translate to holds because Sabalenka won more of the consequential first-serve points and dominated the return.

Set-by-set: 6-4, then 6-3

The first set was a tug of war built on return games. Sabalenka’s first-serve percentage sat at 69 percent, while Townsend posted 79 percent, yet the Belarusian still took 56 percent of points behind her first ball. Second-serve points were scarce for both, 13 percent for Sabalenka and 11 percent for Townsend, which kept rallies short and returners interested. On the return, Sabalenka led 50 percent against first serves and 88 percent against second serves. She converted four break chances to Townsend’s three and won 25 receiver points to 15, a decisive edge in a 6-4 set.

The second set tilted more firmly Sabalenka’s way. She raised her first-serve percentage to 85 percent and won 71 percent of those points, a clear uptick in control. Against Townsend’s serve, she still held 47 percent on first-serve returns and 80 percent on second-serve returns. That balance delivered three more breaks for Sabalenka versus one for Townsend. The top seed also authored the longest game run in the match, taking five in a row at one stage. With service points 14 to 11 in Sabalenka’s favor and receiver points 13 to 6, the 6-3 scoreline fit the pattern.

Winners, errors and shot patterns

Shot-making numbers show why the favorite pulled away. Townsend actually finished with more total winners, 15 to 13, thanks in part to her aggressive serving patterns. Sabalenka’s forehand was the shot that most hurt, though, accounting for 8 of her 13 winners. Both players tallied three backhand winners, and groundstroke winners leaned Sabalenka’s way 11 to 9. There was no volley clinic here, as neither player registered a volley, lob, overhead or drop-shot winner on the stat sheet.

Errors ultimately separated the two. Sabalenka kept her total to 20, while Townsend finished on 30. Unforced errors were 14 to 17, with Sabalenka cleaner on the forehand side at 5 to 9. Townsend had more backhand errors overall, 15 to 7, and more groundstroke miscues, 27 to 20. In a match where return games were plentiful, fewer mistakes on baseline exchanges became a major edge. Sabalenka balanced measured aggression with control and let the numbers work in her favor.

What this win means at the US Open

For the top seed, this Round of 16 win sends her into the quarterfinals on hardcourt with a very clear blueprint. The return game traveled, and the error count stayed manageable. Even without a standout ace tally or a sky-high first-serve percentage, she found a reliable mix of first-serve point conversion and break-point finishing. That adds up deep in a Grand Slam draw, especially on the quick Arthur Ashe stage.

For Townsend, several positives remain. The serve generated free points, and the total of 15 winners showed she could take control of rallies. The next step is turning that first-serve percentage into more holds by winning a higher share of first-serve points and trimming errors in longer exchanges. At this level, holding serve consistently is the hardest needle to thread when the opponent is returning like this.
