INDIANAPOLIS — David West scored 21 points and Lance Stephenson had his league-best fifth triple-double of the season, leading Indiana past Oklahoma City 102-97 Sunday — putting the Pacers one win away from clinching the Eastern Conference’s top seed.

The Pacers (55-26) lead two-time defending champion Miami by half a game with one to play and hold the tiebreaker based on conference record.

“We’re going to treat it (the season finale at Orlando) like a playoff game. We have to get that No. 1 spot,” Stephenson said. “That’s what we wanted from the beginning of the season.”

Kevin Durant finished with 38 points for Oklahoma City (58-22) on a day it could have locked up the second seed in the West.

PORTLAND — LaMarcus Aldridge scored 26 points, including the go-ahead jumper in overtime, and the Portland Trail Blazers defeated the Warriors 119-117 despite a season-high 47 points from Golden State’s Stephen Curry.

With the victory, Portland (53-28) was assured of at least the fifth seed in the playoffs. Golden State sits behind the Blazers in sixth.

Notes

Mike Conley scored 24 points and Memphis pulled away in the third quarter to beat the host Los Angeles Lakers 102-90, moving the Grizzlies a game ahead of idle Phoenix in the race for the final Western Conference playoff berth.

DeMar DeRozan scored 30 points and the Toronto Raptors (47-33) tied a franchise record for victories with a 116-107 win over the host Detroit Pistons.

• The Pistons will not renew the contract of Joe Dumars, president of basketball operations, several media outlets reported. Dumars, who has run the organization for 14 seasons, has agreed to remain as an executive adviser.
