Nyck de Vries topped the Formula 2 free practice session at Spa-Francorchamps, 0.01 seconds ahead of Sergio Sette Camara.
Prema driver de Vries, who took his first F2 feature race win last time out at the Hungaroring, set his fastest time inside the first 10 minutes of the 45-minute session.
Hungaroring pole-sitter Sette Camara came second ahead of the two main championship protagonists George Russell and Lando Norris.
Points leader Russell was 0.475s away from de Vries’ time and 0.179s ahead of Norris, who jumped into his Carlin F2 car straight after making his Formula 1 practice debut for McLaren, with just 25 minutes between the two sessions.
Ralph Boschung was fifth fastest for MP Motorsport, with his new team-mate Dorian Boccolacci 15th in his first outing in an F2 car.
Luca Ghiotto was sixth ahead of Antonio Fuoco, Alex Albon, Maximilian Gunther and Jack Aitken.
