DALLAS (CBSDFW.COM/AP) — It’s the first time in more than 20 years that Mavericks fans didn’t head to the season’s first game at the American Airlines Center and expect to see Dirk Nowitzki.

The reins have officially been passed and Wednesday night Luka Doncic won a showdown with Bradley Beal because the star Dallas guard stayed in the game while his Washington counterpart was ejected after the last of several fourth-quarter exchanges between the two.

Not long after, Kristaps Porzingis had a one-handed dunk on an alley-oop to help the Mavericks turn away a late rally by the Wizards.

Perhaps not exactly how the Mavericks saw the European pair tag-teaming on the way to a win in their long-awaited first game together, but effective nonetheless.

Doncic had 34 points and nine rebounds, Porzingis finished off his 23 points with the game-sealing dunk in the final minute and the Mavericks beat the Wizards 108-100 in the season opener.

“It’s just hoops,” Beal said. “You see it when I got kicked out, he came over and he was the first one to dap me. We weren’t fighting. That was just basketball, trying to frustrate him. He was kicking our butt. Had to do something.”

Washington rookie Rui Hachimura, the first Japanese-born player drafted in the first round, had 14 points and 10 rebounds. The ninth overall pick out of Gonzaga scored his first points before Porzingis hit his first bucket as a Maverick.

The Wizards had cut a 23-point deficit going into the fourth quarter to seven when Doncic and Beal were called for double technicals with 1:09 remaining. Beal was ejected when he was almost immediately whistled for a second technical.

Doncic missed the free throw and a 3-pointer, but the Mavericks kept the ball alive and Jalen Brunson found a cutting Porzingis for the slam.

Porzingis missed his first four shots before taking a break and coming back to score nine points in the final 2:45 of the first quarter. The 7-foot-3 Latvian acquired in a blockbuster deal with the New York Knicks before the trading deadline last season was 7 of 16 from the field.

Doncic and Porzingis traded long 3-pointers throughout the game, finishing 7 of 16 between them (4 of 9 for Doncic, 3 of 7 for Porzingis). Doncic was 12 of 19 overall to help the Mavericks win their opener for the first time in four years.

The Slovenian guard and reigning NBA rookie of the year could have played with Porzingis last season, but the Mavericks decided to let the 2018 All-Star continue recovering from a knee injury in what ended up being his final game for the Knicks 20 months ago.

“It’s finally here,” Porzingis said. “I just want to enjoy the moment. I don’t want to put too much pressure on myself when I’m out there. Most importantly I’m here to win. I’m not here to chase something individually.”

Beal scored 19 points less than a week after the All-Star guard signed a $72 million, two-year extension that will go through the 2022-23 season, with a player option after that. The Wizards are without his backcourt mate, John Wall, who tore an Achilles tendon last December.

“Give our guys credit, they battled back and then they cut the lead to a respectable number,” coach Scott Brooks said. “Brad came in and almost made it more interesting than the final score.”
