Jelly Belly's Jeremy Powers spent most of stage four at the Amgen Tour of California in the break with former cyclo-cross rival Lars Boom (Rabobank). The two helped form the day's major escape on the early climb of Sierra Road and moved out to a lead of 6:30, before being brought back by the peloton with less than 10km-to-go.
