Deuce Tatum, Jayson Tatum’s son, is a big fan of the Boston Celtics.

You can often see the 4-year-old boy cheering for his dad from the sidelines at TD Garden when he’s not on the court or with the team. As of Wednesday night, the Celtics were ahead 2-0 in the first round of the NBA playoffs against the Brooklyn Nets.

Following behind 24-year-old Jayson, Deuce skipped through the locker room after the game, which Boston won 114–107. The Celtics posted a video of this on their Instagram page.

Marcus Smart, the Celtics’ point guard and 2022 Defensive Player of the Year, yelled, “Yeah Deuce!” with excitement as Deuce came on, which made all of his peers cheer.

Before sitting down, Deuce got a high five from Daniel Theis, a center for the Celtics. In the clip, someone says, “He’s got a little skip to him!”The Celtics also took a picture of Jayson and Deuce sitting next to each other in the locker room. Deuce was sitting on a black chair next to his dad’s locker, and they posted the picture on social media.

Jayson liked the picture so much that he tweeted it Thursday morning with the words “Nothing better than this dad s—t.”

A clip from ABC6 in Providence that was shared on Twitter shows Deuce having fun with a basketball on the court at TD Garden before Wednesday’s game.On December 6, 2017, Jayson had his son. He was 19 years old and in his first season with the Celtics. Since then, Deuce has become a big hit with players all over the NBA, not just the Celtics.

Jayson told reporters at the 2022 NBA All-Star Weekend in February that he didn’t think his son would be so well-known.He said in a video clip that The Boston Globe shared on Twitter, “It’s cool, and he likes it.” “People cheer every time he comes to a home game.” When he comes to games, both on the road and here at All-Star Weekend, people yell his name. There is something unique about him.

Jayson also said that one “plus” of having a son at age 19 is that he and his son are “growing up together.”

The Celtics star told the Globe, “I think it’s cool that he’ll be able to see me as my career goes and, since he’s getting older now, remember certain things and interact and things like that.” It’s in fact a plus.”

Afterward, he said, “On the court, I want Deuce to remember me as a competitor who always craved victory.” He sees that I give it my all every time he comes to the game and do everything I can to help us win. Being a winner is the most important thing in team sports as he gets older; everything else will come after.
