Johann Zarco has passed teammate Jorge Martin to claim a thrilling first MotoGP victory in his 120th premier-class start.

Martin led every lap but the last in what was close to a perfect performance, but the Spaniard gambled his victory chances on the soft rear tyre that let him down in the final 10 laps.

The Pramac rider was a sitting duck as his seemingly insurmountable 3.5-second lead in the middle of the race was whittled down to nothing by a four-rider pack that smelt blood.

Title leader Francesco Bagnaia has failed to directly qualify for the top 10 on the grid for the second week in a row in a crucial timed practice session headed by KTM teammates Brad Binder and Aussie Jack Miller.

Bagnaia had been off the pace all session and found himself needing to set a competitive time in the last three minutes of the hour.

Championship rival Jorge Martin, among a gaggle of other riders, disrupted his rhythm by picking up his slipstream on his first lap. Bagnaia attempted to shake the pack but in doing so compromised his first lap, which ended with an unrepresentative time.

It was a funny atmosphere on Phillip Island on Friday night.

Nothing had really changed, but at the same time everything had changed.

Practice had gone ahead without a hitch, the circuit basked in glorious sunshine. But the forecast was close at hand for every team and rider, with brows furrowed about the viability of holding a grand prix in the high winds predicted for Sunday.

Daniel Ricciardo returns to the cockpit for this weekend’s United States Grand Prix with little on the line but much to prove.

Ricciardo’s grand plan to find himself a place at a race-winning team is coming together. He spent the months after being axed from McLaren deconstructing and rebuilding himself in the Red Bull simulator as a reserve driver, and after just 10 rounds he got the nod to replace the ousted Nyck de Vries at sister team AlphaTauri.

His first two races were promising, but the run ended suddenly with a practice crash in the Netherlands that broke his left hand and left him unable to drive until this weekend.

MotoGP has brought forward the Australian Grand Prix to Saturday afternoon in a bid to avoid inclement weather forecast for Sunday.

The 27-lap grand prix will now take place at 3:10pm tomorrow instead of the sprint, less than three hours after the conclusion of qualifying.

The sprint will be moved to 2:00pm on Sunday in the feature race’s original slot.

Jack Miller is hopeful his upgraded KTM can take the fight to dominant Ducati at his home Australian Grand Prix this weekend.

Miller has had a roller-coaster of a first season with the Austrian brand, bursting from the blocks with a podium in the fourth round but losing his way through the middle of the campaign.

Ducati, meanwhile, has won all but three of 15 races so far this season, with Miller’s former factory team taking six of those via title leader Francesco Bagnaia.

Reigning Australian Grand Prix winner Álex Rins has cast doubt on the running of this year’s race, with high winds forecast to disrupt Sunday running.

Phillips Island has basked in warm and sunny weather on Thursday, but conditions are set to deteriorate over the weekend.

Fresh winds and light showers and will arrive for qualifying and the sprint on Saturday, while Sunday’s radar predicts up to 6 millimetres of rain and strong winds of up to 45 kilometres per hour. Gusts could be as strong as 70 kilometres per hour.
