Russell’s pole position – 0.8 seconds clear of the fastest non-Mercedes car – had sent shockwaves through the paddock on Saturday but the race was initially much closer than qualifying.
Both Ferrari drivers made their expected electric starts, and Leclerc vaulted from fourth on the grid to take the lead at the first corner.
Russell powered past the Ferrari on lap two between Turns 10 and 11 by using extra electrical energy.
But Leclerc was not to go down without a fight and drove past the Mercedes in a similar fashion on the run to Turn Nine on lap three.
Russell tracked Leclerc closely. He challenged for the lead into Turn One on lap nine only for the Ferrari driver to fend him off and leave Russell to fight to retain his position from Hamilton, who by now had joined the leading train of cars.
Antonelli, who had dropped to seventh at the start before fighting back past Norris, Lindblad and Isack Hadjar’s Red Bull, then joined them to make it four cars in the leading group after 10 laps, and they circulated together until Hadjar retired on lap 12.
The Frenchman, who had been running fifth, pulled off on the back straight, bringing out the virtual safety car, usually the trigger for teams to pit and benefit from the reduced time loss compared with pitting under racing conditions.
But while Russell and Antonelli pitted, Leclerc and Hamilton did not. Hamilton immediately questioned the call, saying over the radio: “At least one of us should have pitted.”
Instead, they ran long, sticking to their pre-race plan of a one-stop strategy.
By the time Leclerc pitted on lap 25, Russell was only five seconds behind him, and the Ferrari emerged 14 seconds adrift of the lead.
On fresher tyres, Leclerc might have been expected to narrow the gap to Russell, but he did not, and the fight at the front was over.
