Irish duo Nicolas Roche (Sky) and Dan Martin (Cannondale-Garmin) have finished third and fourth in stage two of la Vuelta a Espana and have assumed the same positions in the general classification.

Stage two was won by Colombian Esteban Chaves (Orica) in 3:57:15, with Tom Dumoulin (Giant-Alpecin) second, just one second behind. 

Roche finished nine seconds behind and Martin 14 seconds down.

Chaves now wears the overall leader's red jersey, with Roche 15 seconds behind and Martin 24 seconds behind in the GC respectively.

2015 Tour de France winner Chris Froome (Sky) finished seventh, 30 seconds behind Colombian Chaves' and losing four seconds to sixth-placed Nairo Quintana in the process.

The victory for Chaves was his first in a grand tour stage, and gives him the lead of the general classification by five seconds ahead of the Netherlands' Dumoulin, whom he edged out in a sprint finish on the 158.7km ride from Alhaurin de la Torre to Caminito del Rey.

Chaves' compatriot Quintana, of Movistar, took an early lead in pursuit of the general classification victory ahead of rival Froome, who is attempting to become only the third man to win the Tour and the Vuelta in the same year.

"I felt this was my moment to do it for the team, I felt like I was in a good position, and in the end I did it, I got this, the [red] jersey," Chaves said.

"[Orica GreenEDGE] talked among ourselves, about how to deal with everybody around us. The main thing we needed to do was just attack these guys, so that's what we did.

"Roche and Dumoulin were good company, and we got there in the end.

"At this point I've just got to keep going and be happy about this day, and think about tomorrow."
