Jaylen Brown scored 37 points as the Boston Celtics beat the Phoenix Suns 127-112 to extend their winning run to four games.
Jayson Tatum added 26 points and Al Horford 24 as victory at home edged the Celtics closer to securing the NBA Eastern Conference’s top seeding for the play-offs.
Devin Booker led the Suns’ scorers with 23 points, with Bradley Beal making 22.
The Celtics are clear leaders in the Eastern Conference with a 52-14 record.
Celtics coach Joe Mazzulla said: “Everything with [Brown] starts with his defensive intensity. Getting off to a great start defensively gets him going and that’s big for our team.
“And he can score on anybody at any time. He’s playing really well-rounded basketball on both ends. It’s fun to watch.”
The defeat for the 38-28 Suns places them seventh in the Western Conference, outside the top six automatic play-off places.
