Stephen Curry and Giannis Antetokounmpo led their teams to series-clinching wins on Wednesday.
Curry scored 30 points in his first start of the play-offs as the Golden State Warriors earned their place in the Western Conference semi-finals.
The Warriors defeated the Denver Nuggets by a score of 102-98.
The Milwaukee Bucks beat the Chicago Bulls.
The Boston Celtics will play the Milwaukee Bucks in the Eastern Conference semifinals.
Curry, who has been out with a foot injury, made five three-pointers, five rebound and five assists, setting up a Western Conference clash with the Minnesota Timberwolves or the Memphis Grizzlies.
"Steph Curry is a special, special player and you will probably never see another player like him again," said Warriors shooting guard Klay Thompson.
Some of the threes he made were so incredible, also getting to the rim and making the pocket pass.
The two-time NBA most valuable player scored 30 points for the third time in the last four games as the Bucks defeated the Bulls.
The victory gave Milwaukee its first post-season series win over the Bulls since 1985.
The team knew what the deal was after the second game, according to Antetokounmpo.
We had to be desperate, we knew what we had to do. We had to compete at a high level.
We have to do it as a team. It isn't a one-man show or two-man show.
We are going to play a different team, a very good team, and hopefully we can do it again.
