OKLAHOMA CITY — Kevin Durant scored 33 points, Russell Westbrook had a triple-double, and the Oklahoma City Thunder beat the Memphis Grizzlies 120-109 on Saturday night in Game 7 of their first-round Western Conference playoff series.

Westbrook had 27 points, 16 assists and 10 rebounds. His assist total tied the franchise record for a playoff game set in 1987 by Nate McMillan when the team was still in Seattle.

The gritty Grizzlies, playing without leading scorer Zach Randolph because of a suspension, led by 11 points in the first half before the Thunder overwhelmed them and shot 66 percent after the break.

Marc Gasol led Memphis with 24 points. Grizzlies point guard Mike Conley had 20 points and nine assists while playing with a strained right hamstring.

It was Westbrook’s second triple-double in the past three games. He made 10 of 16 shots from the field, both of his 3-pointers and five of his six free throws.

Durant, slowed for much of the series, looked like his normal self. The regular-season scoring champion made 12 of 18 field goals and all five of his 3-pointers after struggling from long range throughout the series.

Guards Tony Allen and Mike Miller started for the first time in the series in place of Randolph and Tayshaun Prince, and the Grizzlies beat the Thunder at their fast-paced game in the first quarter. Memphis shot 60 percent in the opening period to take a 36-27 lead.

Oklahoma City chipped away in the second quarter, and the Thunder finally took a 51-50 lead on a 3-pointer by Durant.

Durant hit another 3-pointer with 3.7 seconds left to give the Thunder a 61-58 lead at the break. He scored 21 points in the first half and Westbrook had 13 points and eight assists.

Gasol scored 15 points in the first half, but he and Allen both had three fouls at the break.

The Thunder opened the second half on a 10-2 run. Durant hit a 3-pointer to give Oklahoma City a 71-60 lead. Durant hit another 3 that gave Oklahoma City a 78-63 advantage and led to a Memphis timeout.

Back-to-back 3s by Derek Fisher and Westbrook and a breakaway dunk by Caron Butler gave the Thunder a 92-76 lead, and Oklahoma City took a 94-81 edge into the fourth quarter.

PACERS 92, HAWKS 80: In Indianapolis, Paul George scored a playoff career-high 30 points and Roy Hibbert finally came up big to lead Indiana past Atlanta in Game 7.

Indiana staved off elimination for the second time in three days.

It’s the first time since mid-March the Pacers’ regular starters have won back-to-back games.

Instead of becoming the sixth top seed to lose in the first round of the current 16-team playoff format, the Pacers will be back on their home floor Monday night against Washington in the Eastern Conference semifinals.

Kyle Korver scored 19 points and Jeff Teague had 16 for Atlanta, which won just 38 games in the regular season but proved to be a tough opponent for the Pacers.

The game turned on a 24-6 run over a 10:02 stretch that spanned the second and third quarters.

That gave Indiana a 57-40 lead it never surrendered.

Hibbert, who scored 20 points total in the first four games, had a series-high 13 points and seven rebounds. Lance Stephenson finished with 19 points, 14 rebounds and five assists.

George added 11 rebounds for his sixth double-double in the playoffs.
