PORTLAND, Ore. — The Portland Trail Blazers exercised fourth-year options today on the contracts of forward LaMarcus Aldridge and guards Sergio Rodriguez and Brandon Roy.

The Blazers also said exercised their third-year option on center Greg Oden, who missed last season following microfracture surgery on his right knee after being selected No. 1 overall in the NBA draft.

The moves, announced 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.
