San Antonio at Mavericks
(7 p.m. Sunday, American Airlines Center, Dallas)
TV: Bally Sports Southwest
Radio: ESPN 103.3 FM (Univision 1270 AM, Spanish)
About the Mavericks (29-22): If they want to slam a door in the Western Conference standings, this would be the opportune moment. The Mavericks have a nice lead over the Spurs and Memphis Grizzlies in the Southwest Division. A win Sunday night will give them the tiebreaker against the Spurs and a five game lead in the loss column over the Spurs, although Memphis still remains just two games back in the loss column .
