Alexander Bublik joins Team Diadem — and builds his own racket
The career-high world No. 10 signed with Diadem in April 2026. Instead of endorsing a finished frame, he is developing one with Diadem's engineers.
Alexander Bublik, the Kazakh player with a career-high ATP ranking of No. 10, joined Team Diadem in April 2026. What makes the signing unusual is what comes with it: Bublik is not endorsing a finished racket. He is building one.
Project Bublik
Diadem calls the current version Project Bublik — a checkpoint in an ongoing development process between Bublik and its engineers. Every iteration goes on sale in the same form he tests, and he currently plays the Project Bublik 98.
A growing pro roster
Bublik joins a Team Diadem roster that Diadem says spans nine players across the ATP, WTA and pro pickleball tours, including Elina Svitolina (career-high WTA No. 3) and Yuta Funemizu, Japan's No. 1 pro pickleball player.
