The 2025 Next Gen ATP Finals lost one of its biggest names in Czech Jakub Mensik.
The 20-year-old world No.19 pulled out of the event due to injury. Mensik had a breakout 2025 season, winning the Miami Open title to become the second youngest champion in that tournament’s history.
Mensik will be replaced by Germany’s Justin Engel, the world No.187, in the event which takes place from December 17-21 in Riyadh, Saudi Arabia.
18-year-old Engel enjoyed a solid season both on the ATP Tour and the Challenge tour in 2025. At Stuttgart he became the second-youngest player, after Rafael Nadal, to claim a tour-level win on all three surfaces (since 1990).
Engel will join Learner Tien, Alexander Blockx, Dino Prizmic, Martin Landaluce, Nicolai Budkov Kjaer, Nishesh Basavareddy and Rafael Jodar in Jeddah, Saudi Arabia. The 20-and-under event takes place from 17-21 December.
Here are all the previous winners at the Next Gen ATP Finals, a list which includes Carlos Alcaraz, Jannik Sinner, Joao Fonseca and Stefanos Tsitsipas.
