Hello and welcome to live coverage of stage 9 of the Giro d'Italia - the first major mountain test as the riders tackle the infamous Blockhaus at the end of the 149km stage from Montenero di Bisaccia.

Quintana now holds a 28-second lead over Pinot on GC, with Dumoulin up to third place at 30 seconds. It's all to play for with that time trial on Tuesday after tomorrow's much-needed rest day.

Confirmation of the top ten in today's stage...

The moment Nairo Quintana won the stage and rode into pink...

Former race leader Bob Jungels comes home 3:30 down in the wheel of Jan Polanc, the maglia azzurra. That's his pink jersey gone. Tejay Van Garderen comes over about 3:55 down. Adam Yates, who was involved in that crash, finishes 4:38 back - his challenge as good as over. The same can be said of Geraint Thomas, who, bloodied and bruised, comes over 5:09 down on winner Quintana. What a day of drama...

Tanel Kangert of Astana comes home two minutes down for seventh, then Ilnur Zakarin at 2:14. Formolo and Amador come home before Kruijswijk, who loses 2:45 on a day to forget.

Thibaut Pinot outsprints Tom Dumoulin to take second place around 25 seconds down. Bauke Mollema then comes home at 40 seconds and Vincenzo Nibali at one minute. Domenico Pozzovivo arrives for sixth place at 1:18. They're going to arrive in dribs and drabs now...

Victory for Nairo Quintana of Movistar! 50 years after Eddy Merckx took the first win here on Blockhaus, the little Colombian moved into the race lead with a superb ride.

Under the banner for Quintana, who will win this stage and take the maglia rosa. What a ride it has been. But would Thomas or Landa have been able to keep up with him? We'll never know...

We're not getting any time checks for many of the riders - certainly not for Nibali - but Quintana still has 30 seconds on the chasers, Pinot and Dumoulin. The Dutchman could well take the pink jersey from Quintana, however, after Tuesday's time trial. It's wonderfully poised - just a huge shame that Team Sky's chances were dealt that cruel blow by the stationary police motorcycle.

Pinot has found another gear and drops Mollema and Dumoulin. But the Sunweb rider digs in and manages to close the gap.

What a ride by the Dutch duo - they have now caught Pinot.

Nibali is really cracking now - he's been dropped by Mollema and Dumoulin. Pinot trails lone leader Quintana by 26 seconds. The Colombia has entered a wooded section of this climb, which will offer some shade from the sun.

Pinot has launched an attack in pursuit of Quintana - and the Frenchman has dropped Nibali, who is about to be caught by the Dutch duo of Mollema and Dumoulin. Caught and passed, I may add!

Quintana has opened up a 13-second gap over Pinot and Nibali. He will be in pink today - and it's hard to see anyone else taking it from him over the course of the rest of the race. The Jungels group is 1:55 down and will soon be caught by Thomas, who is clawing back lost time after that huge crash at the foot of the climb.

We're onto the hardest part of the climb - which peaks at 14% - and it's here where Quintana attacks! He opens up a little gap, but Nibali stays seated and is not panicking. Further back, Van Garderen has been dropped by the Jungels group.

Quintana has another pop but to little avail. Now he swings back and lets Pinot and Nibali take up the slack. The three chasers are just 15 seconds back.

Thomas now has Deignan with him but it will be a difficult end to the stage for the Welshman - all about damage limitation. His elbow and knee are bloodied after that horrific crash with the motorcycle, which took out around a dozen riders.

Another unseated attack from Quintana, but Nibali doesn't panic and drags Pinot back onto the wheel of the Colombian. Behind it's Dumoulin, Mollema and Pozzovivo about 25 seconds back. Kruijswijk was with them but faded.

Now Pinot has a pop! The Frenchman surges clear but the others close it down.

ATTACK: Quintana has a dig and it blows the pack apart. Only Nibali and Pinot can follow him...
