LOS ANGELES, Aug. 23 (Ticker) -- Lisa Leslie collected 28 points and 12 rebounds as the Los Angeles Sparks celebrated their fourth straight regular-season Western Conference title with an 83-70 victory over the San Antonio Silver Stars.

The Sparks actually clinched the top seed in the Western Conference earlier Saturday when Houston lost at Seattle. Los Angeles will open the postseason against fourth-seeded Minnesota, a team it has beaten 16 straight times.

San Antonio pulled within 63-57 on Margo Dydek's basket with 6:39 left. But Los Angeles answered with six straight points and Shaquala William's basket with 5:36 to go made it 69-57.

Mwadi Mabika scored 16 points and Nikki Teasley added 15 and nine assists for Los Angeles, which closes the regular season Monday against Houston.

San Antonio concluded its first season in Texas with a 12-22 mark, including a 3-14 road record. The season was marked by the firing of coach Candi Harvey on July 26 and interim coach Shell Dailey guided the struggling team to a 6-6 mark to close the season.

Last season, the then-Utah Starzz reached the Western Conference finals before they were swept by the Sparks.

Margo Dydek poured in 23 points for the Silver Stars.
