Piastri beats Norris in rain-delayed Belgian Grand Prix

SPA-FRANCORCHAMPS, Belgium :Oscar Piastri passed McLaren teammate and title rival Lando Norris with a bold early move to win the rain-delayed Belgian Grand Prix and extend his Formula One lead to 16 points on Sunday.

Charles Leclerc was a distant third for Ferrari as reigning champions McLaren celebrated their sixth one-two finish in 13 races and the third in a row.

The race at Spa-Francorchamps was red-flagged after an initial formation lap and delayed by an hour and 20 minutes due to the weather, with standing water and heavy spray affecting visibility.

Piastri was in no mood for hanging around when the racing got going with a rolling start after four laps behind the safety car to check conditions.

The Australian slipstreamed Norris through the daunting Eau Rouge and then scythed past down the Kemmel straight into Les Combes in a move of total commitment in the treacherous conditions.

"I knew lap one would be my best chance of winning the race. I got a good exit out of Turn One, lifted as little as I dared out of Eau Rouge," he said.

"The rest of the race we managed really well. I struggled at the end. Maybe the mediums were not the best for the last five or six laps. We had it mostly under control."

The win was his sixth of the season, making the 24-year-old the first Australian - on a list that includes past world champions Jack Brabham and Alan Jones - to triumph so many times in a single campaign.

Norris had a slight battery issue, the Briton asking over the radio why he had "no pack" before his race engineer assured him it was coming back, but he was not looking for any excuses afterwards.

"Oscar just did a good job. Nothing more to say. Committed a bit more through Eau Rouge, and had the slipstream and got the run," he
