Big Names Fall at Flushing Meadows
The 2026 US Open mixed doubles tournament delivered a major surprise when top seeds Novak Djokovic and Aryna Sabalenka were eliminated earlier than expected. The star pairing looked dangerous from the beginning, but Henry Patten and Katerina Siniakova produced a strong comeback to win their opening match. The defeat came by a 1-4, 4-2, 10-2 scoreline, sending the experienced doubles team into the quarter-finals.
Djokovic and Sabalenka had attracted plenty of attention even before stepping onto the court together. Djokovic brings 24 Grand Slam singles titles and enormous experience on the biggest stages, while Sabalenka entered as a four-time major singles champion and one of the leading names in women’s tennis. Their combination was expected to create plenty of excitement during the revamped US Open mixed doubles event.
Instead, the tournament produced an early upset that nobody had expected from the top seeds.
Strong Start Quickly Disappears
Djokovic and Sabalenka actually began the match in convincing fashion and took the opening set 4-1. Their powerful baseline games appeared to be working well against Patten and Siniakova during the early exchanges. The Serbian and Belarusian stars looked comfortable enough to suggest that the match could become a straightforward opening-round victory.
That feeling did not last particularly long.
Patten and Siniakova adjusted their approach during the second set and started putting much more pressure on their opponents. The Czech doubles specialist brought valuable experience into the contest, while Britain’s Patten also understood how quickly momentum can change in this unusual scoring format.
They eventually captured the second set 4-2 and forced the match into a deciding 10-point tiebreak. That short final stage became the biggest turning point of the entire contest.
Patten and Siniakova Take Control
Once the deciding tiebreak began, Patten and Siniakova looked completely comfortable. They moved quickly, attacked the important points and avoided giving Djokovic and Sabalenka much room to recover. The final score of 10-2 showed just how strongly the underdogs finished the match.
Siniakova then completed the upset with an ace out wide on match point. It was a fitting ending for a pair that had gradually taken control after losing the opening set.
Patten later acknowledged how unforgiving the format can be, particularly because one poor stretch can change an entire match. His comments highlighted an important difference between traditional Grand Slam doubles and the shorter mixed doubles structure being used at the US Open this year.
Why The Format Matters
The US Open mixed doubles competition has undergone a major transformation, with organisers moving the event into a standalone position before the main singles tournament. The changes were designed partly to attract more high-profile singles players who normally might not enter mixed doubles during a Grand Slam.
That strategy has clearly worked when it comes to attracting attention.
Djokovic and Sabalenka were among several major stars involved in the 2026 competition. Serena Williams teamed up with Carlos Alcaraz, while other notable combinations also appeared throughout the draw. The event has become a significant attraction during the early US Open week, rather than simply remaining a smaller competition running alongside the singles tournament.
The shorter format, however, can also create unexpected results.
One Bad Stretch Can Change Everything
Traditional tennis generally gives players more time to recover after a poor game or difficult set. The new mixed doubles format leaves much less room for that kind of recovery. Matches move quickly, and a team can find itself facing elimination after only a handful of bad points.
That appeared to be exactly what happened to Djokovic and Sabalenka.
They had enough quality to win the first set comfortably, but their opponents refused to panic. Patten and Siniakova stayed involved and waited for their opportunity. Once the momentum shifted, they were able to make the most of the deciding tiebreak.
This is also where specialist doubles knowledge becomes extremely important. Singles champions can have incredible groundstrokes and serving ability, but doubles requires different positioning, communication and point construction.
Siniakova Brings Doubles Expertise
Siniakova was particularly important in the upset because she has extensive experience as a doubles player. Her understanding of net positioning and fast exchanges helped her team handle the pressure created by Djokovic and Sabalenka.
Her ability to close the match with an ace also showed the confidence she developed during the comeback. Against players with the reputation of Djokovic and Sabalenka, finishing points under pressure is never simple.
Patten also played an important role by maintaining the team’s energy after losing the opening set. Instead of allowing the early setback to become decisive, the British player and Siniakova reset their approach and forced the favourites into uncomfortable situations.
That adjustment ultimately made the difference.
Djokovic And Sabalenka Had Big Expectations
The pairing had been one of the biggest talking points before the US Open mixed doubles competition began. Sabalenka and Djokovic had previously shared plenty of playful moments around tennis events, but this time they were entering the court with a genuine competitive target.
The official US Open had confirmed them as the top seeds before the tournament started. Their entry was part of a wider attempt to bring elite singles players into the mixed doubles competition.
Sabalenka also had significant doubles credentials despite being better known for her singles career. She previously reached the top of the doubles rankings and has won two Grand Slam women’s doubles titles with Elise Mertens.
Djokovic, meanwhile, has extensive experience handling pressure but has not built the same doubles career as some specialist players. That contrast made their partnership particularly interesting from the beginning.
Mixed Doubles Gets More Attention
The early elimination of Djokovic and Sabalenka is unlikely to reduce interest in the competition. If anything, the upset makes the remaining matches even more unpredictable.
The revamped tournament has already attracted major crowds and a collection of high-profile players. Organisers introduced the changes to make mixed doubles more appealing to fans and encourage leading singles competitors to participate. The format has generated strong commercial interest, although some established doubles players have criticised the changes for reducing opportunities for traditional doubles specialists.
There is also a significant financial incentive for the teams involved. The restructured event has helped place mixed doubles closer to the centre of attention during US Open week, rather than treating it as a secondary competition.
For fans, the shorter matches create another interesting element because almost every game can carry enormous importance.
What Comes Next For Both Stars
Djokovic and Sabalenka will now shift their attention back toward their singles campaigns. Their mixed doubles exit does not change their importance in the main US Open draws, where both players remain among the biggest names competing at Flushing Meadows.
For Djokovic, every Grand Slam appearance continues to attract enormous attention because of his historic record and long career at the highest level. Sabalenka also arrives with major expectations as one of the leading women’s players and a recent US Open champion.
The mixed doubles defeat may therefore become little more than an unexpected opening chapter before their main tournament campaigns begin.
For Patten and Siniakova, however, the victory means much more.
They have removed the top seeds and earned a place in the quarter-finals, giving them a genuine opportunity to push deeper into the tournament. Their confidence should also be high after recovering from a first-set loss against one of the most celebrated pairings in the draw.
A Reminder About Doubles Tennis
The Djokovic-Sabalenka defeat also offers a useful reminder that doubles tennis does not always follow singles rankings. A player can dominate the singles tour and still face problems against a specialist doubles combination that understands positioning and quick exchanges.
Patten and Siniakova showed exactly why experience matters in this format. They did not need to overpower their famous opponents from the first point. Instead, they stayed competitive, waited for opportunities and produced their best tennis when the match became most important.
That approach turned a seemingly unlikely result into one of the biggest surprises of the tournament so far.
Final Takeaway From The Upset
The early US Open mixed doubles exit for Novak Djokovic and Aryna Sabalenka has added another unexpected twist to an already star-filled competition. The top seeds won the first set but could not maintain their advantage against Henry Patten and Katerina Siniakova, who responded brilliantly and dominated the deciding tiebreak.
The result also highlights how unpredictable the revamped mixed doubles format can become. Shorter matches leave little space for recovery, while experienced doubles specialists can quickly exploit small openings. Djokovic and Sabalenka will now focus on their singles challenges, while Patten and Siniakova move forward with growing confidence. For tennis fans, the upset is another reminder that rankings and reputations never guarantee what happens once the match begins.
