Kawhi Leonard scored 36 points, Landry Shamet hit two clutch 3-pointers late and the Los Angeles Clippers beat the Dallas Mavericks 110-107 for their fourth straight win. Dallas ended a four-game winning streak, and more importantly, lost a key piece in center Dwight Powell just as they welcomed back Kristaps Porzingis. Porzingis scored 10 points on 4-for-17 shooting in his return after missing 10 games with right knee soreness. Late in the first quarter, Powell went down on a non-contact play with a right Achilles tendon injury.
