THUNDER 95, MAVERICKS 79

DALLAS (AP) - Kevin Durant finally found his postseason shooting touch to get Oklahoma City off to a quick start, and the Thunder never trailed on the way to a 95-79 victory over the Dallas Mavericks on Thursday night for a commanding 3-0 series lead over the defending NBA champs.

After two close games on their home court, the young Thunder ran away with Game 3.

They will run away with the first-round series with one more win. Game 4 is Saturday in Dallas.

Durant finished with 31 points on 11-of-15 shooting. The three-time NBA scoring champion was a combined 15 of 44 in the first two games of the series, though he had a game-winning jumper with 1.5 seconds in the opener.

Russell Westbrook added 20 points for the Thunder.

Dirk Nowitzki had 17 points to lead Dallas.

HEAT 87, KNICKS 70

NEW YORK (AP) - LeBron James scored 32 points, including eight straight to start the fourth quarter and break open the game, and the Miami Heat took a 3-0 lead, sending the New York Knicks to an NBA postseason-record 13th straight loss, 87-70 on Thursday night.

The Heat held the short-handed Knicks to eight field goals in the second half and will go for the sweep Sunday afternoon.

Dwyane Wade added 20 points for the Heat and Mario Chalmers had 19, hitting consecutive 3-pointers in the fourth quarter when the Heat finally brought some beauty to what had been an ugly game.

Carmelo Anthony scored 22 points but shot 7 of 23 for the Knicks, who are playing without Amare Stoudemire, Jeremy Lin and Iman Shumpert.
