OAKLAND, Calif. (AP) -- The Golden State Warriors have exercised their third-year option on shooting guard Klay Thompson.

The announcement Thursday will keep Thompson with the Warriors through the 2013-14 season.

The 22-year-old played in all 66 games last season. He averaged 12.5 points, 2.4 rebounds, 2.0 assists and 24 minutes to earn first-team All-Rookie honors.

Golden State drafted Thompson 11th overall out of Washington State. He led all rookies in 3-point percentage at 41 percent, and 3-pointers made with 111.

The Warriors open the regular season Wednesday night at Phoenix. Thompson is expected to start at shooting guard this season.
