Cooper Flagg produced a night for the record books on Sunday as the Dallas Mavericks routed the Brooklyn Nets 130-93 at American Airlines Center, becoming the first teenager in NBA history to record at least 25 points, 10 assists and five rebounds in under 30 minutes of playing time.

The 19-year-old finished with 25 points, a career-high 12 assists and five rebounds in just 28 minutes, shooting 8 of 13 from the field and 6 of 6 from the free-throw line. He did not play after the 8:28 mark of the fourth quarter, with the result long since settled.

Flagg sets the tone from the start

Flagg had 20 points and seven assists by half-time, and Dallas never trailed after the opening minutes. The Mavericks led by as many as 37 points, scored at least 30 points in every quarter and shot a season-best 57.1 per cent from the field on their way to a season-high points total.

The 37-point winning margin was Dallas's largest ever against Brooklyn and its biggest in any game since October 2022. It was the Mavericks' second straight win, lifting them to 6-4, while the Nets fell to 2-8.

Kyrie Irving added 21 points against his former team and Daniel Gafford scored 18 on 7-of-8 shooting, with six different Mavericks scoring off Flagg passes. Michael Porter Jr led Brooklyn with 19 points and nine rebounds, while Julius Randle managed 13 and finished minus-33.

A career night for the teenager

The performance was Flagg's third consecutive double-double and his fourth of the season. His previous career high for assists was 11, set at Miami on 26 October, and he passed it with five assists in the third quarter alone after handing out seven in the second.

Flagg, last season's Rookie of the Year, also provided one of the highlights of the night early in the second quarter, throwing down a dunk over Nets forward Noah Clowney that brought the home crowd to its feet.

Head coach Dusty May, who joined Dallas in June after winning the 2026 national championship at Michigan, has watched Flagg grow quickly into the team's creative hub. Six teammates scored from his passes on Sunday, and his 12 assists came with only a handful of turnovers in a controlled display.

What comes next for Dallas

The Mavericks stay at home to host the Indiana Pacers on Monday night to close a back-to-back, having already beaten the Pacers 121-105 on 23 October. Brooklyn, meanwhile, must regroup quickly after a second heavy defeat in a difficult start to the season.

For Flagg, the record is another marker in a rapid rise. He has now scored 20 or more points in a half 16 times in his young career, and Sunday showed he can run an offence as well as finish it. If he keeps producing nights like this, the Mavericks' season may be remembered as the year their teenager became a star.
