Monta Ellis had a season-high 37 points and assisted on the go-ahead basket to spoil Dwight Howard's best offensive night for Houston, and the Dallas Mavericks rallied to beat the Rockets 123-120 Wednesday night.
Dallas was down one when Ellis drove and zipped a pass to Shawn Marion in the corner for the go-ahead 3-pointer with 47 seconds left.
Houston's James Harden had a chance to tie it with 9 seconds left but missed the second of two free throws. Jose Calderon made two free throws after a Houston foul, and Harden shot an airball on a 3-point try in the final seconds.
Howard made his first 11 shots and scored a season-high 33 points.
