Dennis Johnson scored 23 points and Larry Bird had 22 points and 18 rebounds as the Boston Celtics beat the Los Angeles Lakers, 105-99, yesterday in Inglewood, Calif.

Boston opened a 10-point lead early in the fourth period and then held off the Lakers to register a sweep of the defending NBA champions in their two-game series this season.

The Lakers, led by James Worthy's 35 points, missed seven straight shots in the final minute.

Boston, winning its third straight and 15th of 16, got critical help from three reserves -- Jerry Sichting had 11 points and Rick Carlisle and Bill Walton each had 10.

The Lakers' Magic Johnson had 12 assists but failed to make a field goal.

The game was interrupted three times by flaring tempers in the second quarter. First, Lakers guard Byron Scott had to be restrained after receiving a technical foul for throwing the ball at Sichting. Just 35 seconds later, players again had to be held apart after Celtics reserve Greg Kite fouled Michael Cooper hard from behind on a layup try. In the final minute of the half, Kite sent Abdul-Jabbar to the floor with another hard foul. Spurs 113, Kings 94

Jeff Lamp, midway through a 10-day contract, scored 16 points as San Antonio's reserves scored 51 points at home against Sacramento.

Lamp made six of 10 shots and had five rebounds in relief of Mike Mitchell. Ray Williams, also with the Spurs on a 10-day contract, had 10 points in the third quarter. The Spurs' Alvin Robertson had eight steals. Mavericks 120, Bulls 114

Rolando Blackman scored 13 fourth-quarter points -- including two baskets and three free throws in the final two minutes -- to lift Dallas to victory in Chicago. It was Chicago's sixth straight loss. Hawks 110, Trail Blazers 101

Reserve Cliff Levingston stepped in for all-star Dominique Wilkins (sprained left knee) and scored 25 points to lead visiting Atlanta. It was Portland's sixth straight loss.
