Piastri sets pace in chaotic Singapore GP practice session

Championship leader Oscar Piastri went fastest Friday in a chaotic second practice session for the Singapore Grand Prix punctuated by two crashes, red flags and a bizarre pit lane shunt.

Piastri sped round in Imin 30.714sec, 0.132sec ahead of RB's Isack Hadjar with Max Verstappen's Red Bull third just O.11sec further back.

It was a return to form for the Australian, who crashed last time out in Baku but managed to avoid the trouble at the Marina Bay Circuit to top the time sheets.

"I found my feet on the medium at the end there and then the soft felt good," said Piastri, who lamented that 22 minutes of the session were lost to stoppages.

"Obviously not much representative race running," said the Australian, who leads the title race by 25 points from his McLaren teammate Lando Norris, and by 69 over Max Verstappen in third.

"But the car's been in a good place and I feel like I've learned a lot today. That's the aim of practice. So it's been a good day."

The session was first halted by George Russell crashing his Mercedes at turn 16.
