Fabio Quartararo made MotoGP history at the Spanish Grand Prix after becoming the first rider to secure four consecutive pole positions at the Jerez circuit.

The 22-year-old Monster Energy Yamaha rider, who won on each of the last two occasions he clinched pole at Jerez, set an early benchmark with a time of one minute and 36.807 seconds.

He was nearly toppled from top spot by his former team-mate Franco Morbidelli, who at one point got to within 0.005 seconds of a provisional pole position. 

Frenchman Quartararo's first time ultimately would have been enough to secure pole, but he went even better with a later run.

He ended the session with a best time of one minute and 36.775 seconds to secure first spot on the front row, with a 0.057s advantage over Petronas Yamaha's Morbidelli.

"It felt really good today," Quartararo told his team's official website. "Jerez is one of the tracks that I really like. I have ridden a Yamaha four times at this track and four times I got pole position. It's quite an amazing moment, I'm really happy about this.

"But I will say that today's Q2 session was a qualifying where I was more on the limit. I thought I was going to crash in turn six and turn 13. I made a mistake in turn six, but ultimately what matters is that we got the pole position today.

"Tomorrow it's not going to be easy, but I feel prepared and that I have good potential. The medium and hard tyres are both working well, so we will use the warm-up tomorrow to decide which one we will use."

Ducati team-mates Jack Miller and Francesco Bagnaia will start in third and fourth respectively, ahead of LCR Honda rider Takaaki Nakagami in fifth.

Repsol Honda's former world champion Marc Marquez, meanwhile, put in a career-worst qualifying performance and will start Sunday’s race in 14th.

Fabio Quartararo overcame a poor start to win a dramatic Portuguese Grand Prix that saw Marc Marquez finish seventh on his long-awaited return.

Marquez said he was ready to "suffer" in his first race since sustaining a season-ending broken arm last July, but the six-time MotoGP champion enjoyed an encouraging comeback after making an early move from sixth to third.

However, it was Quartararo who took the victory, despite dropping down the field from pole position in a pulsating start, after Johann Zarco and Alex Rins crashed out in quick succession at the Algarve International Circuit on Sunday.

Quartararo took over from Zarco as championship leader after sealing back-to-back wins following his triumph in Doha, with Francesco Bagnaia and Joan Mir taking second and third place respectively.

Maverick Vinales could only finish back in 11th place on a great day for Quartararo.

Zarco darted up the inside in a dream start from third on the grid to take the lead from Monster Energy Yamaha rider Quartararo, with Marquez also impressing during the opening laps in Portimao.

Quartararo dropped back to sixth and Marquez caught the back of Mir's Suzuki as he slipped back following a promising beginning to the race.

Rins, who started in second, moved passed Pramac Racing's Zarco in a flash at Turn 13 to hit the front before Jack Miller and Miguel Oliveira - winner on home soil last year - crashed out.

Quartararo had ominously put a disappointing start behind him to apply the pressure, becoming the latest leader of the race with 17 laps to go.

Rins tried his best to cut the gap in second place but spun off 11 laps from the end at Turn 10 after Valentino Rossi had crashed out from 11th place.

Quartararo was in complete control when Rins spun and a second-placed Zarco hit the deck, with Ducati rider Bagnaia holding off Mir for second, having been back in 11th, as the early championship lead changed hands.

Marc Marquez will start from sixth on his MotoGP return, but there was drama and controversy at the front of the grid in Portuguese Grand Prix qualifying on Saturday.

Six-time champion Marquez will race this week for the first time since the 2020 season opener.

The Repsol Honda superstar broke the humerus in his right arm in that event in Jerez and failed in his bid to make a swift comeback, instead watching the remainder of the campaign from the sidelines as Joan Mir claimed his crown.

Marquez has taken precautions at the start of the new MotoGP year, too, missing the first two races, but he is back in action at the Algarve International Circuit.

His previous appearance in Portugal, at Estoril in Moto2, ended in victory in 2012.

Still recovering his fitness, Marquez said: "Tomorrow I'll suffer. But then next week I can recover, then Jerez be a little bit stronger."

A solid Q2 time of one minute and 39.121 seconds was sixth-fastest to ensure a competitive Sunday start, although Marquez would have only made seventh had Francesco Bagnaia's sensational time not been struck off.

Bagnaia, who claimed a first career pole at the season opener, believed he was set to start from the front of the grid again after shattering the track record. The Italian already has three fastest laps over the past two seasons.

But the factory Ducati rider passed through a yellow flag zone following Miguel Oliveira's crash in completing a 1:38.494 lap.

Fabio Quartararo was the beneficiary when that effort was cancelled, promoted to pole as Bagnaia fumed.

"For sure [the flag position is a problem], because you are coming from the downhill and the yellow flag was on the right side," said Bagnaia, whose strong start to the season has included 26 points from two races. He had 47 from 11 in 2020.

"I was already leaning for the corner and preparing for the corner, so it was impossible to see my side.

"[Luca] Marini, who was behind me, said to me the same. He also didn't see the yellow flags, so it was impossible."

Quartararo will be looking to protect his new position, having only finished on the podium in four of his past 16 races but won on all four occasions.

Fabio Quartararo claimed his first MotoGP race win since Catalonia last year as Monster Yamaha secured a second successive Grand Prix triumph in Qatar.

Quartararo has been open about his struggles with the pressure of mounting a championship bid in 2020 but, having worked closely with a psychologist in recent months, will be hoping his win in Doha is the start of something special.

It was already a momentous occasion for rookie Jorge Martin, who secured pole in just his second outing in qualifying for a premier-class event, and the Spaniard held firm at the front for much of the race.

With his Pramac Racing team-mate Johann Zarco for company at the front, Martin looked in good shape but there was always a sense some of the big hitters from further down the field were just biding their time.

Alex Rins (Team Suzuki Ecstar) was the first to make his move but ultimately lost out in his tussle with Zarco, while reigning champion Joan Mir (Team Suzuki Ecstar) and Jack Miller (Ducati Lenovo Team) engaged in some risky jostling as they looked to get themselves in position for a late surge.

The pair touched a couple of times, including a particularly hefty bump on lap 13 that saw them exchange gestures, though both stayed up.

Francesco Bagnaia (Ducati Lenovo Team) also looked a threat for a while but misjudged the first turn at the start of lap 17 and lost four places.

It was around this time that Quartararo, who started fifth, began to make his move as he looked to match his Monster Yamaha colleague Maverick Vinales' win last time out.

It did not take him long to get around Zarco and by the end of the 18th lap he had passed Martin, who quickly responded only to be overtaken once again by the persistent Quartararo.

Martin kept the pressure on but Quartararo never looked unduly worried in the final stages, while Zarco finally managed to pass his rookie team-mate to finish second and seal successive podium finishes.

Francesco Bagnaia targeted "a really great result" at the Qatar Grand Prix after setting a stunning lap record on his factory Ducati debut.

Third-year MotoGP rider Bagnaia had finished 15th and 16th in his two seasons with Pramac Racing but has quickly focused on loftier ambitions following his bow with the factory team.

Ducati - winners of the previous two Qatar GPs with the since-departed Andrea Dovizioso - had been fast all week at the season opener, with Jack Miller setting the practice pace in his 100th grand prix with a best time of one minute and 53.387 seconds ahead of second-placed team-mate Bagnaia.

But Bagnaia later suggested he had believed he could run in less than 1:53 in qualifying and so it proved, a magnificent 1:52.772 setting a two-wheel lap record at the Losail International Circuit.

That was enough for a healthy 0.266-second gap to Fabio Quartararo, while Bagnaia gave veteran Valentino Rossi - a four-time Qatar winner - a tow to take him to the front of the second row.

Rossi has 10 podiums at Losail and his next in MotoGP will make him the first to 200.

Even from his commanding position, Bagnaia could be forgiven for being pessimistic after his year-high six abandonments in 2020 - including five in the final eight races - but he was full of positivity following an outstanding display.

"I'm very happy," he said. "Already yesterday I was thinking it was possible today to arrive at (1:)52.

"In the second attempt, when I started pushing, I thought it was possible. After the third sector, I was very close to this lap time.

"I'm very happy; my first pole position in my first race with this team. I would like to make everything possible to finish the race tomorrow in the best way possible. I think we can make a really great result."

Miller had to settle for fifth, next to Rossi, as he pursues a third straight podium for the first time in his career following two to end 2020.

Quartararo also had reason to be disappointed with his day as he mistimed his second run and the chequered flag denied him the opportunity to challenge Bagnaia.

Another debutant at a factory team, Yamaha's Quartararo won the first two races of the season last year but has had only one podium in 12 outings since.

The 21-year-old, who has colleague Maverick Vinales - the 2017 Qatar winner - behind him in third, said: "It's a shame I couldn't do the second lap on my second run. I had the chequered flag for a second.

"But I'm quite happy. I think we did a great lap. We tried something in FP4 that was bad, honestly - I didn't feel great on the bike. But I feel that we have great potential for tomorrow.

"We will go with that bike for the race because it's the one that I feel good [on]. I think we made too much changes today, but I'm feeling happy.

"I think we did a great, great job in the qualifying. Now we're just missing the race. I can't wait."

Neither the Ducatis nor the Yamahas should have to worry this weekend about defending champion Joan Mir, who failed to capitalise on the absence of Repsol Honda great Marc Marquez.

Mir was forced to contend in Q1 and will start from 10th, having finished eighth in his only previous Losail entry in 2018.
