Cooper Flagg scored 26 points and recorded eight assists as Dallas defeated Oklahoma City 120–96 on October 28, handing the Thunder their first loss of the season.
The Mavericks improved to 3–2, while Oklahoma City slipped to 4–1. Dallas used an 11–0 run early in the third quarter to pull away after taking a 65–59 halftime lead. The Thunder managed 37 points in the second half and shot 30% after the break, according to Field Level Media.
Flagg added five rebounds and finished without a turnover. P.J. Washington contributed 18 points and nine rebounds as Dallas received double-digit scoring from eight players.
Three-point shooting created a substantial gap. Dallas made 16 of 45 attempts, including 11 before halftime, while Oklahoma City finished five of 32. The Mavericks’ lead reached 27 in the fourth quarter.
Kyrie Irving scored 15 points, with 13 coming in the first half. It was his first home regular-season appearance since the March 2025 game in which he tore his left anterior cruciate ligament. He had sat out this season’s home opener on the second night of a back-to-back.
Ajay Mitchell led Oklahoma City with 29 points, and Shai Gilgeous-Alexander added 21. The Thunder played without Jalen Williams, Cason Wallace, Chet Holmgren and Alex Caruso.
The victory was Dusty May’s first home win as Dallas coach. Both teams next play Houston: the Mavericks host the Rockets on Friday, and the Thunder visit Houston on Saturday.
