Billie Jean King Cup qualifiers 2026: Great Britain teenager Mika Stojsavljevic has pulled off a huge upset

The opening day of the 2024 Billie Jean King Cup qualifiers delivered one of the tournament’s earliest upsets, as 17-year-old British wildcard Mika Stojsavljevic defeated world No. 56 Australian rising star Talia Gibson in straight sets on Friday. The final scoreline of 7-6(0), 7-5 marked a career-defining victory for the teenager, who entered the matchup ranked 219 places below her opponent at world No. 275.

Gibson, who turned heads at the 2024 Australian Open after advancing to the second round of the main draw, entered the match as the clear favorite. The 21-year-old Australian showed flashes of the dynamic talent that has pushed her up the global rankings in the last 12 months, but a consistent string of unforced errors ultimately derailed her campaign. From the opening game, Gibson struggled to find consistent control of her groundstrokes, giving away cheap points that shifted momentum to her young opponent early.

The first set unfolded with an early exchange of breaks, as both players tested each other’s serve consistency before holding for the rest of the set to force a tiebreaker. It was here that Stojsavljevic demonstrated poise far beyond her 17 years, racing out to a 4-0 lead that Gibson never recovered from. The young Brit’s towering, powerful serve proved to be the decisive edge of the match: she landed four aces to Gibson’s single one, and closed out the opening set with a blistering ace down the T to seal the tiebreaker 7-0.

Stojsavljevic carried that momentum into the second set, immediately putting pressure on Gibson’s first service game by jumping out to a 0-40 advantage. Though Gibson fought back to hold serve and keep the set level, she could not resolve her unforced error issue or break through Stojsavljevic’s dominant service game. A critical unforced mistake from Gibson at 2-1 allowed Stojsavljevic to claim the decisive break, putting her up 3-1 in the set.

Speaking to broadcast commentators after the upset, former world No. 4 Jelena Dokic highlighted the mental dynamic of the match, noting that Gibson was still adjusting to the pressure of competing as a tournament favorite, while Stojsavljevic had nothing to lose and could play without restraint. Gibson mounted a late comeback push, and held five break points to take the lead in a tense marathon service game at 5-5. Even as fatigue began to show in the young Brit’s movement, she relied on her powerful serve to escape danger and hold serve, before closing out the match to claim the straight-set victory.

The upset win gives Great Britain an early advantage in their Billie Jean King Cup qualifying tie against Australia, setting the stage for the remaining singles and doubles matches to determine which nation advances to the next stage of the team competition.
