APTOS, Calif. (AP) - Peter Sagan of Slovakia won his second straight stage with a powerful and unchallenged sprint and retained the overall lead Monday in stage 2 of the Amgen Tour of California.

      Sagan (Liquigas-Cannondale) was provisionally timed in the 117.1-mile road race from San Francisco in 5 hours and 2 minutes. He now leads the eight-day event by 8 seconds over Heinrich Haussler

      Haussler (Garmin-Barracuda) of Australia, a former Tour de France stage winner, was second for the second straight day, a half-dozen bike lengths behind.

      Leigh Howard (Orica-GreenEDGE) was third in the stage that took the starting field of 128 along the California coastline.

      Sagan was among 10 cyclists who crashed 73 miles into stage 2. All of the fallen riders returned to the field.
