Max Verstappen, the other racer in the championship fight, sitting 36 points behind behind Norris, was classified in 17th position as his team opted for a alternative strategy.
His teammate the Japanese driver was the sole competitor to have an incident, though minor, when he lost control at the fourth corner soon after starting.
Tsunoda slid over the track edges before rotating through the escape zone, and was fortunate to avoid just a minor contact of the fence.
Ferrari's the seven-time champion also lost it, at the conclusion of the practice, spinning around through the high-speed corner approaching the final corner on to the start-finish straight.
The veteran ended the session in 19th, just behind team-mate the Monegasque driver.
