Kyrie Irving poured in 28 points to help keep the Boston Celtics in first place in the Eastern Conference with a 110-104 overtime win against the host Washington Wizards 110-104 on Thursday night.
Irving's efforts were aided by 18 points from Jaylen Brown and 15 from Marcus Morris for Boston, which remained a game up on Toronto atop the East standings after the Raptors' win in New York.
Otto Porter Jr. had 27 points and Bradley Beal netted 18 for the Wizards, who were playing their seventh straight game without John Wall after the All-Star point guard underwent left knee surgery.
Boston bounced back from a 111-91 rout in Toronto on Tuesday to win for the fifth time in six games. Washington has dropped two in a row after its season-high, five-game winning streak.

After missed 3-point attempts by Beal and Porter, Irving claimed a rebound and was fouled by Beal with 15.5 ticks to go. Irving made both free throws to seal the win.
Boston trailed 51-49 at halftime but outscored Washington 26-19 in a pivotal third quarter to open a 75-70 advantage heading into the fourth.
Porter hit a pair of free throws with 12.8 second to go to in regulation give the Wizards a 98-95 edge. Irving was fouled by Markieff Morris on a leaning 3-point attempt with 9.8 seconds left and made all three free throws to tie it.
Beal's turnaround jumper at the buzzer was off target, forcing overtime.
