The Portland Trail Blazers exercised fourth-year options on the contracts of forward/center LaMarcus Aldridge, guard Sergio Rodriguez and guard Brandon Roy, while exercising their third-year option on center Greg Oden.

The moves, announced today by General Manager Kevin Pritchard, keep all four players under contract through the 2009-10 season.

The Trail Blazers acquired Aldridge, Rodriguez and Roy in 2006 draft day trades.

Portland selected Oden with the No. 1 overall pick in the 2007 NBA Draft.
