Watch: NBA guard Bennedict Mathurin claims Gilbert Arenas' son Alijah Arenas is "scared" of him on the court

During the offseason, NBA players seldom practice in open runs. Alijah Arenas was joined by Indiana Pacers' star Bennedict Mathurin in a similar open run and the competition got intense.

While Arenas gave Mathurin a tough fight, the NBA star had the upper hand. To push Arenas to his limit, Mathurin started trash-talking him mid-game, calling him "scared." Popular social media handle Swish Cultures recorded the open run and posted some highlights on Instagram.

While the duo were going at it, they showed their two-way abilities after scoring and locking down each other. At the beginning of the video, Mathurin is heard trash-talking the 17-year-old to push him:

"Scary a**. He f**king scared… Get the f**k out the way."

Alijah Arenas plays shooting guard for Chatsworth High School in California. He ranks fourth in the 2026 ESPN 60 Recruiting Class and first in his position. According to MaxPreps, Arenas averages 31.8 points, 8.8 rebounds, 2.5 assists, 1.4 steals, and 1.2 blocks per game for Chatsworth.

He has received offers from Kansas, New Mexico, Texas, Nevada, Fresno, UCLA, Xavier, Washington, Ole Miss, Washington, Arizona, California, Nebraska and Virginia.

In Chatsworth High's inaugural game of the season, Arenas broke the Division IV record with 44 points, with his father Gilbert Arenas sitting on the sidelines. However, Chatsworth lost that game 74-66 at the Golden 1 Center.

"I am very grateful. I am very blessed to be in this situation. I felt good knowing that I did something leaving," said Arenas after the game. "I wish I could have left here with the win. I could have left here knowing I could have done that for my team. And I feel like we really played hard and gave it all."
