Oscar Piastri's lead in the Formula 1 drivers' championship has been reduced to 15 points, but it could have been much worse after a hair-raising moment with a backmarker in Austria.
Piastri finished second behind McLaren teammate Lando Norris at the Austrian Grand Prix on Sunday evening, AEST, following an epic duel between the championship rivals.
The battle for the drivers' championship appears to be down to the McLaren duo, after Red Bull's Max Verstappen retired on lap one after being taken out by Mercedes teen Kimi Antonelli.
Piastri battled hard in the early stages of the race. The Australian briefly led on lap 11 of 70 down the back straight, before Norris was able to take the inside line into the tight corner.
A fortnight on from Norris running into the back of Piastri, the Australian came perilously close to crashing on lap 20. He went for an audacious lunge inside Norris, locked his wheels, and just managed to stop the car before collecting his teammate.
"I tried my absolute best, probably could have done a better job when I just got ahead," Piastri said.
"A good battle, probably pushed the limits a little far. Close, but not quite enough."
Piastri had another heart-in-mouth moment on lap 54 when trying to pass backmarkers.

Piastri approached the back of a battle between Red Bull's Yuki Tsunoda and Alpine's Franco Colapinto.
Tsunoda and Colapinto were required to allow Piastri through, but the battle between the two put the Australian in the middle of their fight.
Going down the back straight Colapinto, who told he team he could not see the McLaren driver, pushed Piastri wide and forced the Australian to have his right wheels on the grass.
Colapinto darted to the left just in time, allowing Piastri to get back on the track, but the time loss took away the Australian's realistic chance of catching his teammate ahead.
The Austrian Grand Prix had chaos before the race commenced.
As the drivers went off for the formation lap, Williams driver Carlos Sainz remained stationary on the grid.

Sainz told his team his car was stuck in first gear and would not move.
The Spaniard was finally able to get moving as the other 19 cars were approaching the grid for the race start — which was aborted.
Drama turned to bedlam when Sainz was able to make it around the circuit and go into the pits. From there, Sainz's car then caught fire.
That ended the Spaniard's day as team members and marshals fighting to extinguish the flames.
Neither Williams driver was able to finish the race, with Alex Albon retiring early in the grand prix.

Thank-you to those who joined me throughout the evening.
I look forward to the next blog we share.
Thank you Michael for another wonderful description and commentary on a brilliant and at times frustrating race.
Oscar did very well to probably even finish the race let alone coming a sensational second so everyone should be very proud.
Cheers David
Thanks for burning the midnight oil with me David.
Oscar Piastri has two heart-in-mouth moments.
He nearly crashed into Lando Norris on lap 20, and then was forced off the track on lap 54 byFranco Colapinto.

Ferrari has had a great weekend.
Charles Leclerc finished third, while Lewis Hamilton was fourth.
"I rate our weekend as a team really well," Leclerc says.
"Unfortunately, the pace today was not enough. I think [McLaren] were too fast for us to stay in second, third was the best we could do.
"I don't regret anything we did today, we did the maximum."
There was a brief moment when Oscar Piastri led the Austrian Grand Prix.
He took the lead into turn 3 on lap 11, but then Norris was able to open his rear wing and retake the lead into turn 4.
"I tried my absolute best, probably could have done a better job when I just got ahead," Piastri says.
"A good battle, probably pushed the limits a little far. Close, but not quite enough."
From the start, it was clear this was a battle between the two McLarens.
Oscar Piastri had some chances in the opening 20 laps of the race.
The Australian could not make the move stick, and from there, Lando Norris was excellent.
"It was a tough race, pushing the whole way through, tricky and tiring," Norris says.
"We had a great battle. It was a lot of sun, a lot of stress, but a lot of fun. A nice battle, so well done to Oscar."
Great job by both Lando and Oscar. Thank you, Michael Doyle, for your commentary
