Bobby Portis and Giannis Antetokounmpo combined to score 20 straight points during a 25-0 run midway through the first half and the Milwaukee Bucks coasted to a 135-102 rout of the NBA-leading Boston Celtics on Thursday.

Portis finished with 28 points and Antetokounmpo added 24 while both players had 12 rebounds. Damian Lillard had 21 points in his return to the Bucks’ lineup after missing a 132-116 loss to Utah on Monday for personal reasons.

Milwaukee led by as many as 43 points and its 75-38 lead at the break was the fourth-biggest halftime advantage in franchise history.

Payton Pritchard scored 21 points for the Celtics, who missed 16 of their first 17 3-point attempts and finished 9 of 34 from deep. Boston was back in action after beating Minnesota in overtime on Wednesday and looked fatigued.

The Celtics allowed their highest point total of the season and dropped their second straight road game.

Giddey leads Thunder to historic rout

Josh Giddey had a triple-double and Shai Gilgeous-Alexander scored 31 points as the Oklahoma City Thunder matched the fifth-largest rout in NBA history, 139-77 over the Portland Trail Blazers.

Jalen Williams scored 21 points on 9-of-10 shooting and Giddey finished with 13 points, 12 assists and 10 rebounds for Oklahoma City, which was on the wrong end of the NBA’s biggest blowout, a 73-point loss to Memphis on Dec. 2, 2021.

The Thunder’s 62-point win shattered their previous record for victory margin of 45 points, set twice during the 2012-13 season.

Portland shot a dismal 27.7 percent from the field and suffered its second-worst loss, having fallen by 65 to Indiana on Feb. 27, 1998.

Irving’s big game lifts Mavericks

Kyrie Irving poured in a season-high 44 points and Tim Hardaway Jr. added 32 to lead the short-handed Dallas Mavericks to a 128-124 win over the New York Knicks.

Josh Green scored 18 points, the last coming on a 3-pointer with 25 seconds left to give Dallas a 124-120 lead. Irving and Hardaway combined to make four free throws in the final 11.1 seconds to seal the win.

Dallas superstar Luka Doncic sat out with an ankle injury and Dereck Lively II and Dante Exum also missed the game.

Julius Randle scored 32 points and Jalen Brunson had 30 for the Knicks, who had a five-game winning streak snapped and lost for the first time since acquiring OG Anunoby from Toronto on Dec. 30.

Luka Doncic poured in 49 points and sank a tiebreaking 3-pointer with 26.3 seconds remaining to lift the Dallas Mavericks to a 125-120 win over the Brooklyn Nets on Friday.

Cam Thomas’ 3-pointer with 51 seconds left forged a 120-all tie but Doncic answered 25 seconds later when he banked in a 25-foot hook shot from the right sideline while tightly guarded as the shot clock was about to expire.

The Mavericks superstar shot 16 of 25 – including 9 of 14 from deep – and added 10 rebounds and seven assists.

The game was the first between the teams since the February trade that sent 10-time All-Star Kyrie Irving to Dallas in exchange for Dorian Finney-Smith and Spencer Dinwiddie.

Thomas scored 30 points in his seventh career NBA start, a game after setting a league record by scoring 36 points off the bench in a season opener.

Thomas, though, missed a potential tying 3-pointer with 16 seconds left, and Josh Green sealed Dallas’ win with two free throws three seconds later.

Irving finished with 17 points, seven rebounds and six assists and Tim Hardaway Jr. added 19 points.

Dinwiddie had 23 points and six 3s and Mikal Bridges scored 18 for the winless Nets.

Wembanyama sparks Spurs to OT win

Victor Wembanyama had 21 points, including the tying basket with 20 seconds left in regulation, and the San Antonio Spurs notched a 126-122 win in overtime against the Houston Rockets.

The No. 1 draft pick shook off a slow start and had 16 points, eight rebounds and three blocks in the second half and overtime in his first NBA victory.

Devin Vassell scored 25 points and Keldon Johnson added 20 for the Spurs, who bounced back after a season-opening loss to Dallas on Wednesday.

Wembanyama’s jumper early in overtime sparked a 6-0 run, and he made a pair of free throws with 1:45 left to give San Antonio a 120-115 lead.

Alperen Sengun led the Rockets with 25 points.

Celtics beat Heat in East finals rematch

Derrick White scored 28 points with five 3-pointers and the Boston Celtics defeated the Miami Heat 119-111 on Friday in a rematch of last season’s Eastern Conference finals.

Jaylen Brown added 27 points and Jayson Tatum had 22 for the Celtics, who followed Wednesday’s season-opening victory over the Knicks with a win in their home opener.

Miami squandered a 3-0 series lead against the Celtics last season before winning Game 7 in Boston to advance to its seventh NBA Finals.

Tyler Herro led the Heat with 28 points and sank five of his team’s 16 3-pointers. Bam Adebayo added 27 points and Jimmy Butler scored 14 on 3-of-11 shooting.

Neither team led by more than five points at the end of any of the first three periods and there were six ties and six lead changes in the game.
