(Basketball news) The Boston Celtics knocked out the defending Champions as they beat the Milwaukee Bucks in the final game 7 decider 109-81. For the Celtics, Grant Williams scored a career-high 27 points and hit seven 3-pointers, Jayson Tatum added 23 and Boston set a Game 7 record with 22 3-pointers as Jaylen Brown scored 19 points and Marcus Smart added 11 crucial points. For the Bucks, Giannis Antetokounmpo had 25 points, 20 rebounds and nine assists but he was just 3 of 11 in the paint in the second half, including 1 for 6 the fourth quarter as Jrue Holiday added 21 points and eight assists while Brook Lopez finished with 15 points and 10 rebounds. With this result, the Celtics will face top-seeded Miami beginning Tuesday in a rematch of the 2020 East finals. The Heat beat the Celtics in six games in that series at Walt Disney World.

''As much as it hurt to lose Game 5, I was looking forward to that challenge,'' Tatum said. ''I believe in myself, I believe in this team. I expected to play the way I did and for us to respond the way we did.''

''For me it was like, they're encouraging it, I might as well take advantage,'' Williams said. ''Each one as time went on got more comfortable.''

''Shots that I usually make weren't going in. That's basketball. That's sports,'' Antetokounmpo said. ''Sometimes you win. Sometimes you lose. There's a winner. There's a loser. You've just got to live with it.'

''This is what we played for, why we played the season out, to have home-court advantage in a Game 7,'' Udoka said. ''If you believe in the basketball gods, those things matter.''

Brown said their coach has been the catalyst to put them in this position. ''We didn't want it to be over. We didn't overcome all the stuff we did during the regular season for that to be it. .. At the end of the day, we wanted to come out, leave it all out there. I think we did.''

The Dallas Mavericks produced the upset of the season when they beat the best team in the NBA in game 7 as they took the series 4-3 with a 123-90 blowout victory over the Phoenix Suns. For the Mavericks, Doncic scored 35 points, Spencer Dinwiddie added 30 as both of them were the first teammates to have at least 20 points in a half in Game 7 since Patrick Ewing and Allan Houston did it for the Knicks in 1997. Doncic finished 12 of 19 from the field, including 6 of 11 on 3s. He also got some help in Dinwiddie who had 21 points in the first half with 7-of-10 shooting, including 4 of 5 from 3-point range. For the Suns, Booker finished with 11 points and shot 3 of 14 while Paul had 10 points and four assists as they shot just 37.9% from the field. With this result the Dallas Mavericks are going to face the Golden State Warriors in the Western Conference finals.

''A lot of people said it would be a blowout,'' Mavs coach Jason Kidd said with a grin. ''They were right.''

''We played all season to be in this situation,'' Suns guard Chris Paul said. ''It didn't work out for us.''

''I can't get this smile off my face,'' Doncic said. ''I'm just really happy. Honestly, I think we deserved this.''

''It's still kind of shocking,'' Dinwiddie said

''That group has a lot of character and integrity and I know how bad they wanted it,'' Suns coach Monty Williams said. ''We just could not execute tonight. Couldn't make a shot early, that messed with us a little bit and Dallas played their tails of from start to finish.''

''You could see some of the pressure was on them early,'' Kidd said. ''They missed some shots they normally make.''
