Teenager Mika Stojsavljevic Shocks Sofia Kenin at 2026 Hong Kong Open On One Hour's Notice

Teenager Mika Stojsavljevic Shocks Sofia Kenin at 2026 Hong Kong Open in one of the most startling upsets of the season.

The 17-year-old British prospect arrived at the venue on Wednesday with no expectation of playing in the main draw.

She had already been eliminated in the opening round of qualifying earlier in the week.

Yet by Wednesday afternoon, the London teenager found herself standing across the net from a Grand Slam champion.

Over the course of two hours and 19 minutes, Stojsavljevic produced the match of her young career to defeat Sofia Kenin 6-3, 4-6, 6-4.

The victory marks the teenager's very first win in a WTA Tour main draw.

It also brings an abrupt first-round exit for Kenin, who lifted the Australian Open trophy in 2020.

A LAST-MINUTE SUMMONS

Stojsavljevic was not originally scheduled to step foot on the match court on Wednesday.

Canadian star Leylah Fernandez had been slated to face Kenin in an anticipated opening-round contest.

Fernandez, best known as the 2021 US Open runner-up, was forced to pull out of the tournament shortly before the scheduled walk-on.

A left shoulder injury prevented the Canadian from competing.

Under professional tennis rules, when a main-draw entrant withdraws after the draw is made, tournament organizers look to the qualifying draw for a replacement.

Players who lose in the final rounds of qualifying frequently sign in on site as lucky losers, remaining on standby in case a main-draw player withdraws.

Stojsavljevic, who fell in the first round of qualifying in Hong Kong, was suddenly awarded that reprieve.

The call came with almost no runway to spare.

The Londoner was granted roughly 60 minutes to gather her gear, wrap her mind around the occasion, and devise a game plan against a former major champion.

"I only knew an hour before that I was going to be playing," Stojsavljevic said after the match.

"I kind of just went out and swung," she added.

"We didn't have much time to prepare."

FACING THE RANKING GAP

On paper, the matchup presented an overwhelming mountain for the teenager to climb.

Kenin entered the contest ranked 224 places higher than the British prospect on the WTA computer.

Stojsavljevic arrived in Hong Kong holding a world ranking of No. 411.

Kenin possessed years of experience on the sport's biggest stages, backed by her 2020 Grand Slam crown in Melbourne.

Despite the massive disparity in ranking and pedigree, Stojsavljevic took to the court without fear.

"Obviously, I know she's a Grand Slam champion so it was never going to be an easy match," Stojsavljevic said.

"I kind of just went out and swung today," the 17-year-old repeated.

"I believed in myself and it worked out."

A WILD ROLLERCOASTER ON COURT

From the opening service games, the match developed into a fierce, volatile tug-of-war.

Neither player was able to establish complete comfort on serve in the humid Hong Kong conditions.

Over three tense sets, the contest featured a staggering 11 service breaks between the two competitors.

Stojsavljevic leaned heavily into her aggressive baseline style right from the start.

Her height allowed her to generate free points on serve and attack short balls with heavy groundstrokes.

The Brit struck six aces during the encounter and fired six clean winners.

She proved opportunistic when opportunities arose, converting six of her 13 break-point opportunities against the American.

Stojsavljevic seized the opening set 6-3 with aggressive ball-striking that constantly kept Kenin behind the baseline.

She carried that momentum immediately into the second set, racing to an early break and establishing a 3-0 lead.

KENIN FIGHTS BACK

A former major winner rarely surrenders without a response, and Kenin began to dig into the baseline exchanges.

Stojsavljevic momentarily lost her way from that 3-0 advantage as unforced errors crept into her high-risk strategy.

Kenin mounted a determined comeback, breaking back twice to turn the second set completely around.

The American leveled the set score by claiming the second frame 6-4, shifting all psychological momentum to her side of the court.

Many teenagers playing their first tour-level match would have crumbled under the weight of such a blown lead.

Stojsavljevic, however, reset her focus ahead of the deciding set.

THE DECIDER

Stojsavljevic reclaimed the upper hand immediately in the third frame with another burst of powerful groundstrokes.

She broke Kenin's serve early and surged out to a commanding 4-1 lead in the decider.

Kenin refused to concede quietly, using her counterpunching skills to claw back one of the breaks and narrow the deficit.

With the match hanging in the balance at the finish line, Stojsavljevic held her nerve.

Serving for the match, the 17-year-old created two match points.

Kenin erased the first, but Stojsavljevic slammed the door shut on her second opportunity.

With a final winner, she secured the 6-3, 4-6, 6-4 triumph and celebrated the biggest result of her fledgling career.

A MILESTONE IN A BREAKOUT YEAR

The victory over Kenin provides another major highlight in what has been a breakout 2026 campaign for Stojsavljevic.

The Londoner first captured international attention as a junior competitor in 2024.

That season, she captured the US Open girls' singles title in New York.

The triumph made her the first British player in 15 years to win the US Open junior crown, matching the feat accomplished by Heather Watson in 2009.

Stojsavljevic then transitioned that junior promise directly onto the senior stage throughout 2026.
