Jayson Tatum of the Boston Celtics scored his 10,000th career point in the second quarter of Saturday’s 124-114 victory over the Brooklyn Nets.

Tatum, 25, is the youngest player in team history to reach 10,000 points. Antoine Walker, who was 26 at the time, held the previous record.

“It’s kind of hard to process,” Tatum said. “In the moment, it’s a huge accomplishment. I’m extremely blessed to be part of such a great franchise. And I’ve just been fortunate to be on some really good teams; have some really, really good coaches and obviously have some great teammates that have helped contribute to 10,000 points along the way.”

Tatum drove into the lane, turned, and made the layup with 5:05 remaining in the quarter while drawing a foul on Brooklyn guard Cam Thomas. Tatum subsequently made the free throw, giving Boston a 52-48 lead.

This season, Tatum, who was picked third overall in 2017, is averaging 29.8 points per game. He finished with 32 points and 11 rebounds, one of five Celtics in double figures for Boston, which advanced to 5-0 on the season.

“He shows up to work every single day,” Celtics coach Joe Mazzulla said. “He puts in the work and and he dedicates his life to it. He doesn’t miss days. He doesn’t miss practices, games. And just his open-mindedness and wanting to be coached and wanting to be held to a high standard. When you have guys like that — that you can coach — it also allows you to bring the best out of everybody else and so he’s one of the guys that sets the tone for us.”

Tatum joins LeBron James, Kobe Bryant, Kevin Durant, Carmelo Anthony, Tracy McGrady, Devin Booker, Bob McAdoo, Giannis Antetokounmpo, and Dwight Howard as the tenth player in NBA history to score 10,000 career points before the age of 26.
