So, Degenkolb denied the 10th Vuelta win of his career but what a victory for Sbaragli and MTN-Qhubeka, whose dream season continues.
JJ Rojas (Movistar) took third and Tosh van der Sande of Lotto-Soudal fourth.
And it's MTN-Qhubeka's Sbaragli! That was unexpected... but the Italian held off Degenkolb's late surge.
A fast and messy sprint ends with a photo finish between Degenkolb and Kristian Sbaragli...
Degenkolb is there but boxed in and quite far back...
LottoNL-Jumbo attack and Luis Leon Sanchez counters for Astana... into the last kilometre.
It's all a bit messy at the moment, with none of the trains having assembled yet.
No Adam Hansen is driving the pace for Lotto-Soudal - and he's ridden clear with a team-mate... Hang on, no, that's the similar red jersey of Tom Dumoulin, reeling him in. What a legend.
The three leaders have been caught ahead of the 4km-to-go banner.
Giant are in control for their man Degenkolb. Surely this is the ideal opportunity for the German to take his 10th career victory on the Vuelta.
Just eight seconds for Sicard, Elissonde and De Marchi. Brambilla has been caught. The small pack is about 40-strong.
Terrible luck for Henao, who will lose a lot of time today. Kiryienka stopped to help out, but the Colombian was fairly bloodied and bruised.
The three leaders have 24 seconds over the pack, with Brambilla in between.
CRASH: Sergio Henao has gone down hard on a tight corner and it looks like he's lost his bike underneath the barrier and down the side of the mountain.
Elissonde is caught by the two other escapees on the descent. Brambilla is being reeled in by some other riders off the front of the pack. It's all going to come back together. In fact, it's Dumoulin leading the chase like a true patron.
This descent (7.8km at 4.4%) could be key or it could be uneventful. You choose...
Red jersey Tom Dumoulin comes to the front of the pack as Etixx-QuickStep's Brambilla attacks. Further up, Elissonde has a small gap over Sicard and De Marchi as he crests the summit. But the gap back to the pack is just 20 seconds.
Elissonde catches De Marchi and Sicard and wastes no time before dancing clear. Back with the pack it's Tinkoff-Saxo and Giant on the front.
The French duo of Elissonde and Coppel has the leaders in their sights. Coppel drops back his pint-sized compatriot surges clear to make contact.
Mikel Landa (Astana) has already been dropped. The Spaniard, third in the Giro, shipped 15 minutes yesterday.
Sicard is about to join De Marchi on the front. They have 40 seconds over the peloton with a duo in pursuit - Kenny Elissonde (FDJ) and Jerome Coppel (IAM).
They're onto the hairpinned Cat.2 Alto del Desierto de las Palmas (7km at 5.6%) and Alessandro De Marchi (BMC) has attacked. He has Romain Sicard (Europcar) in pursuit.
Front wheel change for Henao after a puncture. The Colombian from Team Sky was in the break earlier - which may be why it was never allowed to stay out (he's just 3:13 down on Dumoulin on GC).
Movistar, Sky, Tinkoff-Saxo and MTN-Qhubeka are all near the front, but it's the team-mates of Senors Valverde and Quintana who are controlling things.
Before the climb there's the small matter of the intermediate sprint - and, to be fair, it is a small matter because, unlike the Tour de France, no one seems to contest the sprints here in Spain. The average speed was up to 44.5kmph after two hours of riding.
It's all over for Terpstra as Tinjkoff-Saxo now come to the front. The pace is high ahead of the final climb, the summit of which comes 17km from the finish.
Now Astana are driving the pace as Terpstra looks to have sat up. The Dutchman has only eight seconds to play with now...
Now that break has been reeled in, as Movistar continue the pace-setting. Terpstra, the lone leader, has 25 seconds.
Just as two riders - including Cofidis' Geoffrey Soupe - join the small break, they are reeled in by the pack. Or practically - they have about 30 metres to play with. Meanwhile, Terpstra still has 18 seconds out ahead.
Roche is still trying to fight back onto the back of the peloton with three Sky team-mates following that crash.
BREAK: Five riders - including two from Tinkoff-Saxo - ping off the front. Niki Terpstra, the Dutch national champion, is there - and it's the Etixx-QuickStep rider who then soloes clear on his own.
It's that man Chaves who wears the green jersey after conceding his red yesterday to Dumoulin. The Colombian is on 71 points - one point ahead of Alejandro Valverde and four points ahead of Dumoulin.
A reminder that Caleb Ewan has withdrawn today. The 21-year-old Australian has one of Orica-GreenEdge's three stage wins in this race, with Esteban Chaves taking the other two.
Luka Mezgec of Giant-Alpecin spoke to Eurosport this morning: "It's going to be hard to control today because a lot of guy will want to get into the break. It will be hard to control for the sprint so we hop some other teams will help out - possibly Trek for Boy Van Poppel." So far, so right for Mezgec.
CRASH: Nicolas Roche goes down heavily on a roundabout. The Irishman has Sky team-mate Salvatore Puccio with him but looks fairly shaken. Roche came down yesterday too, and will add another bloody elbow to his collection.
And that's it, this 40-man split in the peloton has been neutralised and the race is back as one. The Giant-Alpecin team of red jersey Tom Dumoulin and sprinter John Degenkolb set the tempo on the front of the pack. Trek, Movistar and Astana are all near the front too.
Those two groups have come back together but they have just 20 seconds to play with.
The riders have passed through the feed zone. Six riders now lead the race: Vorganov, Montaguti, McCarthy, Puccio, Cummings and Erviti. Then there's 24 riders between the leaders and the peloton, which has caught those intial 10 riders to have dropped back.
The peloton are within one minute now of the leaders, with Giant-Alpecin doing all the chasing for their man John Degenkolb.
Cameron Meyer, George Bennett, Riccardo Zoidl, Amael Moinard, Kenny Elissonde, Jerome Cousin, Luis León Sánchez, Ian Boswell, Rodolfo Torres and Pello Bilbao have all been dropped so we now have 30 riders out ahead. The gap is just 1:15.
This leading group is splitting up on the descent with smaller splinter groups forming. It looks like it will all come back together on the flat ride into the intermediate sprint and the final climb.
Zoidl and Verona are caught by the break, which now has just 1:25 over the peloton as they start a long downhill run into the Uxo valley.
After winning yesterday with Tom Dumoulin, Giant-Alpecin are going all in for John Degenkolb today, which is why this break may struggle. Team director Christian Guiberteau told lavuelta.com this morning: "It's true that I said yesterday I didn't believe in Tom Dumoulin for a stage he finally won but it was a way to wrong foot everybody. Even if I continue to think that the Andorra stage will be complicated, Tom is really incredible and actually we don't know what his limits are. He's a warrior but moreover he's clever and knows how to manage his efforts. His first attacks yesterday were a way to test his legs and the last blow he bore knowingly. Today we're going to defend the jersey, hoping for this work to also favour John Degenkolb."
Meanwhile, away from the Vuelta, Jonathan Vaughters has just confirmed that Etixx-QuickStep's Rigoberto Uran will be riding for Cannondale-Garmin next season. The Colombian - twice runner-up in the Giro - will fill the Dan Martin void alongside Pierre Rolland, who will fill the Ryder Hesjedal-shaped void.
Verona and Zoidl have 55 seconds over the chasing group and 1:30 over the peloton, so the gaps are still very small.
Finally we have confirmation of the top three over the earlier Puerto del Oronet Cat.3 climb: 1. Pello Bilbao, 2. Carlos Verona, 3. Sergio Henao. Bilbao doing his best to preserve the lead of his Caja Rural team-mate Omar Fraile in the polka dot jersey standings: Fraile has 18 points, with Dumoulin and stage 7 winner Bert-Jan Lindeman on 13.
Australian stage 5 winner Caleb Ewan has withdrawn from the race. The Orica-GreenEdge neo pro has been struggling with the pace today.
If you're struggling to get your head around who's in this leading group then this tweet from Movistar should do the trick...
Two of the leading group - Ricardo Zoidl (Trek) and Carlos Verona (Etixx-QuickStep) - have managed to break clear. They have about 15 seconds over the other 38 riders, who have two minutes over the pack.
So, Sky, Ag2R-La Mondiale, BMC and Caja Rural all have three riders in this break. It's quite an intriging one, with no major GC involved except that man Sergio Henao, who is only 3:13 down on Tom Dumoulin. The Dutchman leads the race after his victory yesterday by 57 seconds over Joaquim Rodriguez and 59 seconds over Esteban Chaves.
The coming together has occurred so we have 40 riders now out in front of the pack, with a 2:30 gap. Such is the size of this group - plus the weary legs out there - you have to give them a good chance of staying out. Unless the Giant-Alpecin team of John Degenkolb have their day. The German would be the favourite for the sprint in the absence of Messrs Sagan and Bouhanni.
Three chasers - Johannes Frohlinger, Jérôme Cousin and Jay McCarthy - are in pursuit and should bridge across soon.
News is patchy regarding the passage over the summit of the Puerto del Oronet, but that leading group - or split, really - contains: Dario Cataldo, Matteo Montaguti, Sergio Henao, Carlos Verona, Riccardo Zoidl, Tiago Machado, Daniel Navarro, Peter Velits, Lawson Craddock, Rubén Plaza, Martijn Keizer, Luis León Sánchez, Lawrance Warbasse, Imanol Erviti, David Arroyo, Natnael Berhane, Jurgen Van den Broeck, Romain Hardy, Tsgabu Grmay, Andrey Amador, Pello Bilbao, Eduard Vorganov, Carlos Quintero, Maxime Monfort, Ian Boswell, Salvatore Puccio, Benjamin King, Kenny Elissonde, Stephen Cummings, Cameron Meyer, Amael Moinard, George Bennett, Darwin Atapuma, Ángel Madrazo, Mickael Cherel, Davide Villella, Rodolfo Torres.
The likes of Sergio Henao (Sky), Dario Cataldo (Astana), Andrey Amador (Movistar), Jurgen van den Broeck (Lotto-Soudal), Darwin Atapuma (BMC) and Angel Madrazo (Caja Rural) are all in this big leading group, which is approaching the summit of the first climb.
We join the race on the first climb and there's a large group of 38 riders with about one minute over the peloton.
Sylvain Chavanel (IAM Cycling) tried his luck ahead of the first climb - but the French veteran was caught just before the Cat.2 Puerto del Oronet.
There's was crash in the peloton involving a cluster of riders, including Angel Vicioso (Katusha). They're all back up - and Kiryienka was then caught.
Vasil Kiryienka (Team Sky) managed to edge ahead of the pack after 15km.
Right from the outset Amets Txurruka (Caja Rural) was in trouble at the start of today's stage as the attacks came in thick and fast. The Spaniard was one of many riders caught up in the flurry of crashes in the past two days.
182 riders took to the start of today's stage from Valencia - the final task ahead of Tuesday's much needed rest day. It's yet another sunny day in Spain, but for a change we have the odd cloud in the sky. The temperature is in the early 30s.
Yesterday we enjoyed perhaps the most exciting finish to any stage in any Grand Tour this season as the race favourites traded blow after blow on the final climb at Cumbre del Sol, before Dutchman Tom Dumoulin rounded Chris Froome in the final 50m to secure the biggest win of his career and move back into the red jersey.
