Dallas Mavericks Stun the Phoenix Suns in Game 7 Upset

The Suns had the best record in the N.B.A. in the regular season, and went to the finals last year. 

A Game 7 in the N.B.A. playoffs is supposed to be the most thrilling, intense type of game, where the high stakes bring out the best in both teams.

The top-seeded Suns lost to the No. 4-seeded Dallas Mavericks, 123-90, in Game 7 of the teams’ Western Conference semifinals series on Sunday in Phoenix.

Dallas, which led by 46 points in the second half and never trailed on Sunday, will face Golden State on Wednesday in San Francisco in Game 1 of the conference finals.

The Suns dominated the regular season and set a franchise record for wins with one goal in mind: return to the N.B.A. finals for a second straight year — and win the championship this time.

Doncic scored 35 points with 10 rebounds and 4 assists, without playing at all in the fourth quarter.

Spencer Dinwiddie added 30 points off the bench for Dallas, and Jalen Brunson scored 24.

Dallas' Luka Doncic, left, scored 27 points in the first half. So did the Phoenix Suns

The Suns were led by two All-Star guards: the 25-year-old Devin Booker, and the 37-year-old Chris Paul, in his 17th N.B.A. season.
