BOSTON — Avery Bradley scored a playoff career-high 29 points, and the Boston Celtics beat the Washington Wizards 123-101 on Wednesday night to take a 3-2 lead in the Eastern Conference semifinals.

Al Horford added 19 points, seven assists, and six rebounds. Isaiah Thomas was also active, scoring 18 points and handing out nine assists.

Game 6 is Friday night in Washington, where the Wizards easily won their two games. If the Celtics win, they would move on to host the Cleveland Cavaliers to open the Eastern Conference finals.

Game 7 would be in Boston on Monday.

Boston led by as many as 26 points, negating Washington’s physicality by spreading the floor and sinking 16 3-pointers.

John Wall had 21 for the Wizards, who haven’t won a playoff game in Boston since 1982.

The Wizards scored the first four points of game, but that was followed by 16-0 run by the Celtics.

It marked the fourth time in the series that one team has had a run of at least 16-0.
