Vladimir Radmanovic heads a list of 18 players extended invitations to try out for the Sonics' summer league team.

The Sonics' first game in Southern California Summer Pro League play is against Dallas Thursday in Long Beach, Calif. The schedule ends July 19.

The second-year veteran forward is assured a spot on the team along with first-round draft picks Nick Collison and Luke Ridnour. Ridnour won't play in games because of an avulsion fracture in his pelvic bone but will participate in non-contact drills.

The other Sonics guaranteed a position are forward Ansu Sesay and guard Ronald Murray. Second-round draft pick Paccelis Morlende will compete in the three-day camp in Seattle that begins Monday but will likely return to France.

Other notable invitees include former UCLA forward Matt Barnes, former Gonzaga forward Casey Calvary and guard Richie Frahm, Fresno State forward Hiram Fuller (who prepped at Tacoma's Stadium High) and former Washington guard Donald Watts.
