The 2013 AMA Pro Supercross season starts Saturday at Angel Stadium with the first of 17 rounds. Browse through our season preview gallery for a look at the riders and storylines to watch this year.

Recovered from knee surgery, Ryan Villopoto goes for his third Supercross title in a row beginning Saturday.

Ryan Dungey, front right, team manager Roger DeCoster, front left, and their team won the AMA Pro Motocross championship in 2012, but KTM hasn't won a Supercross title … yet.

Justin Barcia has two 250SX championships and a Monster Energy Cup to show he's ready to run with the big boys in the 450 class of Supercross in 2013.

Angel Stadium in Anaheim, Calif., will be the site of the 2013 Supercross season opener Saturday and two later rounds this year.

When he's healthy, James Stewart (in the Red Bull helmet) is always a good bet to make the podium. "None of us will have the luxury of a bad weekend this year," Stewart says.

One of the top rookies to watch is Dean Wilson, a former Lucas Oil Pro Motocross champion in the 250 class, a two-time runner-up in 250SX and one of ESPN The Magazine's NEXT athletes in action sports.

Justin Brayton moves to Joe Gibbs Racing for the 2013 Supercross season.

Perennial Supercross contender Chad Reed returns from surgery to repair the ACL in his left knee.

Kevin Windham's consecutive main event start streak ended last season, but the 34-year-old rider is 24 starts behind Mike LaRocco's all-time Supercross record (228).

Davi Millsaps finished second overall and was one of just three riders to compete in every main event in 2012.

As they did here in February at the San Diego Supercross, from left, Ryan Dungey, Ryan Villopoto and Chad Reed should be battling it out for podium spots all season long.
