Jan Choinski

Born in Koblenz, Germany, in June 1996 to a British mother and Polish father, Jan Choinski took a long, unglamorous road to the ATP top 100 — and reached it later than most. He switched allegiance from Germany to Great Britain in 2019, and by mid-2026 stands as the country's No. 2 singles player. The junior pedigree was always there: a US Open boys' semifinal back in 2014 hinted at a ceiling it would take more than a decade of Challenger grind to approach.

At 6-foot-5 with a two-handed backhand, Choinski builds his game around a heavy serve and flat, first-strike hitting from the baseline. He's a hold-serve, redirect-the-rally type rather than a counterpuncher, and the height gives him cheap points on first serve when the toss is right — though the same frame can make him a step slow on the stretch against quicker movers.

The career has been built on the Challenger circuit, where he has stacked multiple titles, but the headline moments came at the majors. A 2023 Wimbledon wildcard delivered his first Grand Slam main-draw win, over Dušan Lajović in four sets, before 17th seed Hubert Hurkacz ended the run in the second round. The following season he beat a young Joao Fonseca in qualifying at the Estoril Open for his first tour-level win away from a Slam, and a 2025 return to Wimbledon ended in a five-set first-round loss to Luciano Darderi.

As of June 2026, Choinski has reached his career-high ATP No. 100, achieved on June 29, 2026 — at 30, the highest perch of a slow-burn career, secured just as he heads back into the Wimbledon main draw.
