The Dallas Mavericks opened their NBA Summer League campaign with a commanding 97–87 victory over the Oklahoma City Thunder on July 17, 2026, at the Cox Pavilion in Las Vegas. The Mavericks used a balanced scoring attack and a key second-half surge to pull away from a young Thunder squad featuring several high-upside rookies and second-year players.

Match Overview

Both teams traded baskets through the first half, with Oklahoma City holding a slim 45–43 lead at the break. The Thunder’s aggressive transition offense kept the Mavericks on their heels early, but Dallas tightened defensively in the third quarter, outscoring OKC 30–18 to seize control. The Mavericks’ bench provided a crucial spark, and their veteran summer-league core — including returning second-year players — showed poise in closing out the game.

Key Moments

• Third-quarter turnaround: After a sluggish start to the second half, Dallas went on a 14–2 run capped by a steal-and-dunk from guard Jaden Hardy, forcing a Thunder timeout with 5:34 left in the period.
• Free-throw efficiency: The Mavericks converted 22 of 26 free throws (84.6%), while the Thunder managed just 17 of 26 (65.4%) — a difference that proved critical in the final five minutes.
• Late-game composure: With Oklahoma City cutting the deficit to six points at 90–84 with 2:10 remaining, Dallas responded with a pair of tough mid-range jumpers from rookie wing Olivier-Maxence Prosper to seal the win.

Tactical Story

Dallas head summer-league coach God Shammgod emphasized defensive switching and contested three-point attempts. The Mavericks held Oklahoma City to 32.1% from beyond the arc (9-of-28) and forced 15 turnovers, converting them into 18 points. Offensively, the Mavericks spread the floor with multiple ball handlers, creating driving lanes for Hardy and second-year center Dereck Lively II, who finished with 12 points and 9 rebounds. The Thunder, meanwhile, relied heavily on the pick-and-roll play of guard Cason Wallace and forward Ousmane Dieng, but struggled to generate consistent offense when their initial action was blitzed.

Standout Players

• Jaden Hardy (DAL): The explosive combo guard led all scorers with 23 points on 8-of-16 shooting, adding 5 assists and 3 steals. His ability to create his own shot in the half-court was the difference-maker.
• Olivier-Maxence Prosper (DAL): The third-year forward contributed 17 points and 7 rebounds, knocking down 3-of-5 from three-point range. His defensive versatility allowed Dallas to switch 1-through-4 effectively.
• Cason Wallace (OKC): The second-year guard posted 19 points, 6 assists, and 4 rebounds, showing improved poise in running the offense. He kept the Thunder competitive with a series of pull-up jumpers in the first half.

Summer League Context

While the NBA Summer League standings are less about final rankings and more about player evaluation, the Mavericks’ win places them in the upper tier of the Las Vegas bracket. For Oklahoma City, the loss provides a learning opportunity for their young core, which includes 2025 lottery pick Nikola Đurišić (11 points, 4 rebounds). Both teams will play again within 48 hours as they continue to fine-tune rotations and audition players for regular-season roles. The Thunder will look to improve their interior defense and free-throw consistency, while Dallas aims to build on a promising start that showcased their depth and defensive identity.
