HOUSTON — Dirk Nowitzki scored 31 points, Jason Terry added 24 and Brandan Wright had a career-high seven blocks to help the Dallas Mavericks beat the Houston Rockets 101-99 in overtime Saturday night.

Shawn Marion had 12 points and a season-high 15 rebounds for the Mavericks, who beat Houston for the fifth straight time.

Goran Dragic scored 24 points, and Luis Scola added 19 for the Rockets, who had all five starters in double figures.

The Mavericks came into the game with only a half-game lead over Houston, Utah and Denver in the tightly bunched Western Conference standings. The game had a playoff feel, with 17 lead changes, 15 ties and a louder-than-usual crowd with the in-state rival in town.
