Piastri on top as grass fires, crashes disrupt practice at Suzuka

Oscar Piastri went fastest Friday for a McLaren one-two in a chaotic second practice for the Japanese Grand Prix that was red-flagged four times and saw Jack Doohan crash heavily.

- 

Two of the red flags were for trackside grass fires during a badly disrupted afternoon session in which Australia's Piastri clocked a best lap of 1 min 28.114sec.

Hepipped teammate and championship leader Lando Norris by 0.049sec in dry but blustery conditions at Suzuka, where home hero Yuki Tsunoda showed promise on his Red Bull debut.

Piastri and Norris - who went quickest in first practice -have won one grand prix each in a dominant start to the season from McLaren.

Piastri, who won last time out in Shanghai, called it "a bit of an up-and-down day" after being 15th in first practice.

"But there's definitely been positives in there," he added.
