SAN ANTONIO (Ticker) -- After two straight home victories, the Seattle SuperSonics must figure out how to win at the site of the league's best home-court advantage.

The SuperSonics, who won back-to-back games on their home floor to knot the series at 2-2, visit the San Antonio Spurs in Game Five of the Western Conference semifinals on Tuesday.

Ray Allen scored 32 points and Luke Ridnour added a playoff career-high 20 for Seattle in a 101-89 triumph in Game Four on Sunday.

Ridnour, who made all seven of his shots, scored 15 points in the third quarter and helped spark a 12-1 run after the game was tied, 54-54.

Antonio Daniels scored 19 points and Damien Wilkins came off the bench to add 15 to help offset the loss of Rashard Lewis, who sat out with a sprained left big toe. Lewis is listed as questionable for Game Five.

The Spurs return to the place where they went 38-3 during the regular season and hope to recapture the magic that led them to a pair of double-dight victories to open the series.

Tim Duncan scored 35 points and grabbed 10 rebounds for San Antonio, which committed a season-high 23 turnovers and lost Sunday despite a 40-32 rebounding edge. Manu Ginobili scored 15 points and Tony Parker added 12 for the Spurs.

The series heads back to Seattle for Game Six on Thursday.
