Isaiah Thomas had a double-double of 29 points and 12 assists in the series decider at TD Garden.
The Celtics now advance to face the Cleveland Cavaliers in the Eastern Conference finals. Celtics center Kelly Olynyk was the unsung hero of the night, finishing the night with 26 points, five rebounds and four assists.
The Celtics' reserves scored 48 points to only five for the Wizards' bench, with Kelly Olynyk doing the majority of the damage. Down by three, Isaiah Thomas hit two 3-pointers and Marcus Smart one in a 1:13 span to put the home team ahead to stay.
It was an incredible well-rounded display from the Celtics' entire rotation, but they were carried on the bouncy manbun of Kelly Olynyk, who had the game of his life. "We don't care what others say".
The Boston Celtics have advanced on to the Eastern Conference Finals after defeating the Washington Wizards 115-105 in Game Seven. It is the Celtics' first appearance in the conference finals since 2012.
Now, the challenges gets stiffer with the defending National Basketball Association champion Cavs coming to town.
Olynyk also played football in high school for the South Kamloops Titans. "The game wasn't always what we wanted it to be and it wasn't a ideal game". "We really believe that".
Beal led the Wizards, who have not reached the conference final since 1979, with 38 points. Beal said after the loss. "The only thing that matters is getting a win".
Markieff Morris contributed 18 points and Otto Porter Jr. dropped 20 points also in the game. John Wall and Co. were never able to get over the hump as the Celtics kept them at an arm's length the rest of the way, hitting timely baskets again and again. The run grew to 22-5 in the opening minutes of the fourth quarter as the Celtics' lead became 94-81.
By this point, the Celtics know what the Wizards want to do, and the Wizards know what the Celtics want to do. The Celtics continued their dominance of the Wizards in Boston, beating Washington for the ninth straight time, dating to 2014. Let all of that sink in, and then take in the next part.
Thomas had 9 points in that stretch for Boston. "He was the difference today - a huge difference". The NBA has grown men playing for a team called the Wizards maybe just as bad as the Pelicans. Washington coach Scott Brooks fell to 2-1 coaching in seventh games. He rattled home an open three to start the run and made winning plays all over the floor to keep it rolling.
Thomas, as he has done all season, played his best when the Celtics needed it most. The Wizards need offense from him - or even forward Bojan Bogdanovic, who can provide a spark with his three-point shooting off the bench. "They are going to give them a hell of a fight, and it is going to be an interesting series for you guys to watch".
"Don't come to my city wearing all black talking about it's a funeral", Wall said on ESPN after that game. "So it's a not a satisfied season to me".
With the game tied at 17, rookie Jaylen Brown came off the bench to spark a 7-0, including a 3-pointer and a pair of free throws.
