SAN ANTONIO — Spurs guard Brent Barry opted out of his contract and became a free agent today.

Barry was part of a February trade with Seattle that sent him, center Francisco Elson and a 2009 first-round draft pick to the SuperSonics in exchange for forward Kurt Thomas. Barry, 36, re-signed with the Spurs in March.

Barry, a career .407 3-point shooter, averaged 7.1 points in 31 games with the Spurs last season and 5.2 points during the playoffs.

Jacque Vaughn, 33, who has backed up point guard Tony Parker, exercised his option, meaning he'll be under contract with the Spurs through next season.

Free agents who were with the Spurs last season include forward Robert Horry, who will turn 38 in August and last week told a Houston television station that he wants to play a 17th season, 35-year-old guard Michael Finley and Thomas, who is also 35.
