Lampre-Merida's Nelson Olivera has won stage thirteen of the Vuelta a Espana.
A 178km stage from Catalayud to Tarazona saw a group of around fifty riders get clear but the peloton which included race leader Fabio Aru soon chased them down.
Sylvain Chavanel, Iljo Keisse and Jimmy Engoulvent were the next three to try to break but their time on the front was also short-lived.
Ruben Plaza of Lampre-Merida took the first climb of the day as a part of a group which included Arashiro, Chavanel, Cherel, Coppell, De Marchi and Nelson Olivera took a lead ahead of a chasing group of eight riders which included Nicholas Roche of Team Sky, who were ahead of another chasing group of seven riders.
Everyone, including MTN Qhubeka’s British rider Steve Cummings and Nicholas Roche joined up to form a twenty three man break and after seventy one kilometres, they were 2.16 ahead.
With Romain Sicard of Europcar, the best placed rider at 6.41 down on Aru, the peloton were reluctant to let this group get too far away and immediately started to bring them back.
However, the group pushed on and extended their lead as the winds got up to 4.30.
A minute had been knocked off when Gianluca Brambilla took the sprint before breaks started to happen in the front group and Pavel Poljanski of Tinkoff-Saxo went away with 34kms left and took the points on the category three climb.
On the twenty kilometre long descent, and Nelson Olivera took over the lead, riding at speeds of 76kmh and pulled out a lead of 54 seconds with 12.4kms to go.
Olivera extended that lead and was 1.03 clear as he headed for the flam rouge and then the finish line to take the win in 4.14.01.
Julien Simon of Cofidis was second with Nicholas Roche third, followed by Chavanel and Rojas.
The pelotn finished 4.47 down and means that Fabio Aru retains 27 second lead over Rodriquez.
