Dallas Mavericks advance to the Western Conference finals for the first time since 2011 with a 123-90 Game 7 win over the top-seeded Phoenix Suns.
Dallas won the series after winning the first six games at home, dominating in a hostile environment from start to finish.
The playoff-tested Suns, who reached the NBA Finals with a similar roster last season, were a no-show.
Doncic put the Mavs ahead with his first three shots, including two 3-pointers. Dallas led 27-17 in the first quarter and 57-27 at halftime.
The Suns looked overwhelmed in Game 7. They missed shots they usually make, made bad passes they don't, and looked nothing like the NBA-best 64-win team.
Individual games weren't as close as the series. Three of the first six games were decided by 20 points or more, and none were decided on the final possession.
In Game 7, the road team did all the damage. Doncic shot 12 of 19 from the field and 6 of 11 3s. Dinwiddie scored 21 points on 7-of-10 shooting, including 4 of 5 3-pointers, in the first half.
