Stephen Curry top-scored with 21 points as he helped the Golden State Warriors beat the Dallas Mavericks 112-87 in their Western Conference final opener.
The Warriors restricted Dallas star Luka Doncic to 20 points in what was his lowest score of the play-offs.
"We did what we were supposed to do - protect home court, win the first game," said Curry, who also had a game-high 12 rebounds.
"We had a specific game-plan coming in, and for the most part, we executed it."
Andrew Wiggins scored 19 points for the Warriors and was also key in limiting Doncic's impact.
