Seth Curry scored 29 points, Harrison Barnes added 24 and the Dallas Mavericks beat Miami 96-89 on Monday night, handing the Heat just their third loss in 19 games. Curry looked a little like famous older brother Stephen Curry of Golden State by hitting two long 3-pointers in the fourth quarter, the latter giving Dallas a 90-89 lead. The Mavericks rallied from 14 points down in the first quarter and let an 11-point third-quarter lead get away.
