The Boston Celtics beat the Washington Wizards 123-101 to move to within a game of a place in the NBA's eastern conference finals.
The hosts started strongly at TD Garden on Wednesday and never looked back, sealing a win which moved them 3-2 ahead in the seven-game series.
Avery Bradley led the scoring for Boston with 29 points to make sure Washington need to win game six at home at the Verizon Centre on Friday to keep alive hopes of facing the Cleveland Cavaliers in the finals.
Al Horford added 19 points, seven assists, and six rebounds. Isaiah Thomas was also active, scoring 18 points and handing out nine assists.
If the Celtics win on Friday night they would move on to host the Cleveland Cavaliers to open the eastern conference finals.
Game seven would be in Boston on Monday.
Boston led by as many as 26 points, negating Washington's physicality by spreading the floor and knocking down 16 three-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, including three times in the first quarter.
Washington had a 16-0 spurt to start game one, a 22-0 run in game three and 26-0 burst in game four.
During Boston's first-quarter spurt on Wednesday, the Wizards missed eight-straight shots before it was ended by Otto Porter's basket.
Boston also did a good job of sharing the ball, getting assists on 12 of 13 baskets in the opening 12 minutes.
Thomas had five assists, more than Washington's entire team (four) in the period.
The Wizards responded with more energy after half-time, but each of their mini-runs were quickly beaten back by Boston, which continued to share the ball and take advantage of their fast break opportunities.
