Despite suffering a mechanical near the finish, Rock Racing's Oscar Sevilla scored a win in the opening stage of the San Dimas stage race, a 3.8-mile uphill time trial in San Gabriel Canyon.

While losing more than 30 seconds as he fixed his bike, Sevilla managed a seven-second win over second-placed Peter Stetina (VMG-Felt), who now leads the under-25 category.

In the pro women's division, team High Road's Mara Abbott and Kimberly Anderson took top honors, finish first and second, with times of 15:27 and 16:13 respectively.
