The Golden State Warriors clamped down in the fourth quarter to pull away to a 121-109 victory over the Portland Trail Blazers on Sunday in game one of their NBA playoff series.
Golden State, aiming to get back to the NBA finals for a third straight year and regain the crown they surrendered last season to the Cleveland Cavaliers, had 32 points from Kevin Durant in his first playoff game as a Warrior.
Stephen Curry added 29. Draymond Green was everywhere, finishing with 19 points, 12 rebounds, nine assists, five blocked shots and three steals for the Warriors.
Meanwhile, Jimmy Butler scored 15 of his 30 points in the fourth quarter as the Chicago Bulls held on to beat the Boston Celtics 106-102 in the opener of a first-round Eastern Conference series.
Golden State withstood 75 combined points from the Trail Blazers duo of Damian Lillard and CJ McCollum to triumph in a game that saw 22 lead changes.
They were tied at halftime and knotted at 88-88 after three quarters.
But the Warriors opened the fourth frame with a 15-2 scoring run to seize control.
Backup point guard Ian Clark contributed seven points in the flurry, but it was increased defensive pressure that really turned the tide.
"We let them get to their spots in the first half," Warriors coach Steve Kerr said. "they still made some tough shots, which they're going to do. I thought we did a better job in the second half of being a little more physical."
The Trail Blazers pulled within 105-99 with 5:16 to play. But Green tipped in a Curry miss and Durant produced three straight baskets to stretch Golden State's lead to 113-99 with 3:36 remaining.
Durant, acquired as a free agent after the Warriors' loss to the Cavs in last year's finals, connected on 12 of his 20 shots and also pulled down 10 rebounds.
Game two of the series, a rematch of a Western Conference semi-final last season, is on Wednesday.
Elsewhere in the West, the Rockets and Oklahoma City Thunder tipped off in a series featuring the top contenders in the Most Valuable Player race -- Thunder star Russell Westbrook and the Rockets' James Harden.
- Wall leads Wizards -
Sunday's Eastern Conference action got under way in Washington, where John Wall scored 15 of his 32 points in a dominant third quarter to lead the Wizards to a 114-107 victory over the Atlanta Hawks in their series opener.
Wall also handed out 14 assists while teammate Bradley Beal scored 22 points and Markieff Morris added 21.
German guard Dennis Schroder led the Hawks with 25 points and Paul Millsap had 19. Atlanta made 32 of 39 free throws, but connected on just 43.6 percent of their shots from the floor and turned the ball over 21 times.
In Boston, Butler scored five points during an 8-0 run midway through the final period that put the Bulls in control on an emotional night at the Boston Garden.
Celtics point guard Isaiah Thomas played the day after his younger sister, Chyna, was killed in a car accident.
Thomas led the Celtics with 33 points, hitting a layup with seven seconds left to cut Chicago's lead to 104-102.
But Butler dribbled off a few seconds and sealed the victory with a two free throws with just three seconds on the clock.
Game two of the series is Tuesday at the Garden.
