Rock Racing swept the top four places in Saturday’s prologue time trial at the Tour of Colombia.

Santiago Botero, like he did last year in winning the race, won the 8.3 km time trial, followed by Rock teammates Victor Hugo Peña (seven seconds behind), Oscar Sevilla and Tyler Hamilton (both 14 seconds behind).

Rock Racing is one of three non-Colombian teams (out of 15) in the 15-day race. Results of the prologue can be found here.
