The Dallas Mavericks’ decision to part ways with Nico Harrison seemed to have paid dividends, as Dallas won their first game since his departure, defeating the Portland Trail Blazers 138-133 in overtime on Sunday night at the American Airlines Center. The victory was led by 18-year-old rookie Cooper Flagg, the Mavericks’ No. 1 pick in the 2025 NBA Draft.
Flagg recorded a historic stat line of 21 points, eight rebounds, five assists, two blocks, and one steal. No 18-year-old in NBA history has ever posted those numbers in a single game. Only LeBron James has matched the four non-block categories on three occasions. This also marked Flagg’s first career overtime win, according to StatsMuse.
Flagg’s impact was most visible in the second half and overtime. After entering halftime with just two points, the rookie unleashed a 10-point third quarter. Highlights included a steal, a behind-the-back dribble, and a Euro-step finish through contact for a three-point play. In overtime, he contributed four points, two rebounds, and an assist — including a full-court outlet to PJ Washington that led to a transition dunk, giving Dallas a 132-129 lead with 1:39 remaining.
Washington also had a strong performance, scoring 21 points, with 18 of those coming from five made three-pointers. Daniel Gafford added a season-high 20 points along with six rebounds and three blocks. Off the bench, Klay Thompson provided an impactful scoring boost, hitting five three-pointers en route to 19 points.
Other notable contributors for the Mavericks included Brandon Williams, who finished with 15 points and six assists, and Max Christie, who added 14 points. In total, seven Mavericks scored in double figures as the team shot an efficient 50.5% from the field and 44.1% from three-point range, overcoming seven turnovers in the first quarter.
On the Blazers’ side, Shaedon Sharpe led the way with 36 points and six assists. Deni Avdija contributed 29 points and seven assists, while Jerami Grant added 26 points and five rebounds. Donovan Clingan recorded 16 points and 11 rebounds, and Toumani Camara chipped in a double-double with 11 points and 10 boards.
The victory ended a three-game losing streak for Dallas and improved their record to 4-10. The Mavericks played without Anthony Davis, who continues to recover from a left calf strain and has now missed nine consecutive games.
Dallas will look to carry this momentum into Monday’s road game against the Minnesota Timberwolves.
