Jiří Lehečka’s breakthrough run at the 2026 Miami Open delivered not only the biggest result of his career but also one of the tournament’s most heartfelt moments, as his girlfriend, Lucka Neumannová, was seen visibly emotional in the stands following his semifinal win.
The Czech’s dominant performance to reach his first ATP Masters 1000 final was punctuated by Neumannová fighting back tears, embracing members of his team, and applauding as the magnitude of the achievement set in.
Lucka Neumannová’s Emotional Reaction to Jiří Lehečka’s Miami Open Breakthrough
Lehečka is putting together the most significant run of his career in Miami, where he has advanced to his first ATP Masters 1000 final. Entering as the No. 21 seed, the 24-year-old Czech’s path to the final began with a 6-2, 7-5 victory over French Wild Card Moise Kouame in the second round, followed by a 6-3, 7-6(6) win against Ethan Quinn.
The Czech tennis star’s most notable statement came in the Round of 16, where he upset No. 6 seed Taylor Fritz in three sets, 6-4, 6-7(4), 6-2. He then ended the Cinderella run of Spanish qualifier Martin Landaluce in the quarterfinals with a 7-6(1), 7-5 win.
In the semifinals, Lehečka routed No. 28 seed Arthur Fils 6-2, 6-2 in just 75 minutes. As the final point was sealed, cameras quickly turned to Neumannová, whose teary-eyed reaction and embrace with the coaching team captured the emotional weight of the moment. The moment quickly gained traction online, with clips of Neumannová’s reaction circulating on social media shortly after the semifinal concluded at the Miami Open.

The couple, who have been together since around 2024, have often been seen supporting each other’s careers. Neumannová, a track and field athlete specializing in the 800 meters and 4×400-meter relay, frequently attends his matches at events like Wimbledon and the US Open. She also comes from an elite sporting pedigree as the daughter of Katerina Neumannova, the 2006 Olympic gold medalist in cross-country skiing.
Jannik Sinner vs. Lehečka: Head-to-Head History and Miami Open Final Outlook
Looking ahead, Lehečka will meet Jannik Sinner for the fifth time in his career. The Italian holds a dominant 4-0 head-to-head lead over the Czech, having won every set they have played across the Challenger, ATP, and Grand Slam levels. Their rivalry began in 2019 at the Ostrava Challenger third round, where Sinner won 6-4, 6-2, and continued into 2024 with quarterfinal victories for the Italian at both Indian Wells, 6-3, 6-3, and Beijing, 6-2, 7-6(6).
Their most recent encounter at the 2025 French Open was their most lopsided, as Sinner dismantled Lehečka 6-0, 6-1, 6-2 in a third-round masterclass. Despite this history, their upcoming 2026 Miami Open final presents a new challenge: while Sinner remains the favorite, Lehečka enters the match in career-best form, having not dropped his serve once throughout the entire tournament.
