Maine native Cooper Flagg scored a season-high 43 points and grabbed 10 rebounds in the Dallas Mavericks’ 125-122 win over the Indiana Pacers.

Flagg, 19, of Newport, also finished Monday’s game in Dallas with a team-high six assists and three steals while also blocking a shot.

According to the Mavericks’ basketball communications department, Flagg became the second teenager in NBA history to record at least 40 points, 10 rebounds and five assists in a game. The first player to achieve that feat was Kevin Durant, who finished with 42 points, 13 rebounds and six assists for the Seattle SuperSonics in a over the Golden State Warriors on April 16, 2008.

This also marked the fourth straight game in which Flagg has finished with a double-double. Flagg recorded 19 points and 10 rebounds in a 112-111 loss to the San Antonio Spurs on Nov. 4; 21 points and 10 rebounds in a 112-100 win against the Utah Jazz in an NBA Cup game on Nov. 6; and 25 points and a career-high 12 assists in a 130-93 victory against the Brooklyn Nets on Sunday.

“Whenever I get out there on the court, it just goes back to being a competitor and trying to make as many winning plays as I can and trying to make the easy, right basketball play out there,” Flagg said after Monday’s game.

The 2025-26 NBA Rookie of the Year is off to a strong start in his second NBA season. Entering Tuesday, Flagg is tied for 11th in the league in scoring with an average of 25.9 points per game. He is shooting 50% from the field and is averaging 6.9 rebounds, 6.9 assists, 2.2 steals and 0.8 blocks per game.

Flagg and the Mavericks will be back in action on Thursday, when Dallas faces the Minnesota Timberwolves on the road.
