In a surprising upset at the Mexican Open, 23-year-old Serbian player Miomir Kecmanovic defeated world No. 5 Alexander Zverev in three sets. This marked Kecmanovic's first victory over a top-five ranked opponent, highlighting Zverev's ongoing struggles in key moments of high-profile tournaments.

Why it matters

Zverev, considered one of the finest players never to have won a Grand Slam, has faced persistent questions about his approach during critical phases of matches. This latest defeat to the rising Kecmanovic adds to the debate over who is the best ATP player without a major title.

The details

Despite holding a 4-3 lead in the decisive third-set tiebreaker, Zverev faltered by dropping the last four points, a sequence that ultimately cost him the match. Kecmanovic emphasized his own strategic edge, stating he was "more aggressive when it mattered" and served better than usual.

  • The match took place earlier this week at the 2026 Mexican Open.
  • Zverev will next compete at the Indian Wells Masters 1000 tournament starting on March 4.

What’s next

Zverev enters the upcoming Indian Wells Masters 1000 tournament with an opportunity to approach his game differently, as he is defending just 10 ranking points and the slower court speed may present a chance to test a more aggressive strategy.

The takeaway

This match highlights Zverev's ongoing struggles to capitalize on critical moments, a weakness that has prevented him from claiming a coveted Grand Slam title so far in his career. The loss to the rising Kecmanovic adds to the debate over who is the best ATP player without a major championship.
