Jayson Tatum drain game-winner, Celtics hold off Pistons for win

Getting split in a series against the previously winless Pistons was not the Celtics’ weekend goal, but it took a Jayson Tatum game-winner to keep it from being much worse.

Tatum pulled up from the midrange and drained the 15-footer with 2.9 seconds left on Sunday to give Boston a 122-120 win over Detroit.

“We haven’t been good, especially down the stretch, executing-wise,” Marcus Smart said postgame (he had 17 points on the night). “We got to our spots, we got the ball where we wanted it, and those two players made great shots and great reads. They won us the game.”

Jaylen Brown led Boston with 31 points — he shot 13-of-16 for the game — and hit a critical three late that set up the Tatum game-winner. It was redemption for Brown following a rough outing Friday in Boston’s loss to Detroit, including a late miss that sealed the loss.

Jerami Grant led the Pistons with 22 points, while Sviatoslav Mykhailiuk had 15 points off the bench in the second half.
