SEATTLE (Ticker) -- The Western Conference-leading San Antonio Spurs continue on their five-game road trip as they pay a visit to the Seattle SuperSonics on Sunday.

Brent Barry scored 23 points, including seven 3-pointers, off the bench and Manu Ginobili added 16 as the Spurs posted a 98-79 victory over Portland on Friday. San Antonio was deadly from beyond the 3-point line, draining 12-of-21 shots.

The Spurs are in a heated battle with Dallas (54-16) for the best record in the West and also with Detroit (55-13) for the NBA's top spot and home-court advantage throughout the postseason.

Luke Ridnour recorded 18 points, nine rebounds and eight assists and second-year center Robert Swift scored a career-high 17 points and pulled down 11 boards in Friday's 117-104 loss to Denver.

In its last six contests, Seattle - which is the worst defensive team in the league - is allowing more than 111 points per game.

San Antonio has won three straight and 10 of the last 12 meetings against the SuperSonics, including a 103-78 triumph on February 21. The All-Star duo of Tony Parker and Tim Duncan combined to collect 43 points and pull down 17 rebounds in the winning effort.
