Born on 8 November 2001 in Mladá Boleslav, the son of a swimmer and a track and field athlete, Lehečka grew up in Kněžmost and admired Tomáš Berdych and Radek Štěpánek. As a qualifier on his ATP debut he reached the Rotterdam semi-finals in 2022, and a year later he made the Australian Open quarter-finals. He won ATP titles in Adelaide in 2024 and Brisbane in 2025, reached the 2025 US Open quarter-finals and became the Czech No. 1. In 2026 he reached his first Masters final in Miami and a career-high ranking of No. 12. On grass that summer he reached the Stuttgart semi-finals, lost his opening match at Queen's as second seed, and matched his best Wimbledon result with a fourth round.

Anecdotes
The person behind the player.
Kněžmost, 2000s
A family of athletes
His father was a swimmer and his mother a track and field athlete, and as a boy he skied, cycled and swam. He first held a racquet at three. His grandmother, who had played at national level, was teaching his older sister, so he wanted to play too. He grew up admiring Tomáš Berdych and Radek Štěpánek, and Roger Federer.
Against Daniil Medvedev in his first Wimbledon fourth round, he hit a shot in the eighth game that dropped straight into a spectator's drink. The crowd laughed, and the spectator held the glass up for everyone to see. The rest of the afternoon went less well: he needed a medical time-out and retired after two sets.
A day after his 100th tour-level win, he beat the home favourite Jack Draper 6-4, 4-6, 7-5 to reach his first grass final, the first by a Czech man on the tour since Tomáš Berdych at Wimbledon in 2010. On court he thanked the crowd for being fair: "You don't beat a player like Jack every day."
He won the first-set tie-break against Ben Shelton 7-4 and held two match points in the second. Shelton saved both and took the tie-break 16-14 on his eighth set point, then won the third-set tie-break 8-6 after 2 hours 54 minutes. Shelton went on to win the title the next day.
Two sets down to Alexander Zverev at 3-3 in the third, he walked off at 10:55 p.m. when the referee Denise Parnell halted play before the 11 p.m. curfew. When they returned he won three games in eight minutes to take the set, then lost the fourth-set tie-break 8-6. It was, he said, the first time it had happened to him.
