Julian Arredondo of Trek Factory Racing won the second stage of the Tour De San Luis in Argentina.
The second stage of this 2.1 race was a 170.6 stage from La Punta to Mirador del Potrero and saw 153 riders starting.
Chile's Jonathan Guzman, Sebastian Tolosa of the Buenos Aires team, Sebastian Trillini of the Argentina national team and Christian Martínez & Jorge Giacinti of the San Luis team were the first to escape, taking a 3.22 lead after 15kms.
With a lead of 4.20, the first Meta Sprint of the day at Pasa por El Durazno came after 41.6kms of racing and saw Guzman take the points.
As Leo Messineo abandoned and Trillinihad been shed by the escapers, the lead steadied around the four minute mark, Cristian Martinez was first over the category three La Florida summit with ninty kilometres of the stage remaining.
The quartet continued on their way with Sebastian Tolosa taking the Meta Sprint at el Durazno ahead of Guzman and Giacinti.
With 55kms to go, the quartet still had a lead of 4:25, there was almost a crash between team cars when Antony Delaplace stopped to change his wheel.
Tom Boonen decided that this was the right time to try and split the peloton and around thirty riders went with him but they were not near enough to prevent Tolosa from taking the Meta Sprint at Va de la Quebrada ahead of Giacinti and Guzman.
That was it for Tolosa and he dropped back towards the peloton, leaving Giacinti, Martinez and Guzman who had a 2.41 break going into the final thirty four kilometres and heading towards the Mirador climb.
With ten to go, only Guzman and Giantini were still out front with a lead of just over a minute and just before the climb up to the Mirador del Potrero started, it was groupo compacto and the escapers time in the lead was over for another day.
The final 4.8 kilometres on the 1270m Mirador del Potrero de los Funes offered a 6.7% gradient.
BMC's Peter Stetina and Julian Arredondo of Trek attacked with three to go and they got into the final bend and Arredondo sped away to take the victory with Stetina second and Nairo Quintana third, followed by Atapuma, Pozzovivo, Zubeldia, Santamorita, Caruso, Rubiano and Sepulveda.
Stage One winner Phillip Gaimon continues to lead the race, with a 1.47 lead over Marc De Maar and a 3.56 lead over third placed Christian Meier.
