Jiří Lehečka

Lehečka's record is that of a player who has arrived quickly and is still climbing. He reached a career-high ATP singles ranking of world No. 12 on 25 May 2026, having been outside the top 100 only a few seasons earlier, and he holds the No. 1 position among Czech men. His 2026 season produced a first Masters 1000 final in Miami, an ATP 500 final in Tokyo and a Davis Cup run with Czechia to the Finals after beating the United States in Prague. The two ATP singles titles on his resume came by 2025. For a player who turned 24 in November 2026, the list of deep runs at the biggest events outside the Grand Slams is already longer than most of his peers can match.
