LOS ANGELES (AFP) — The Oklahoma City Thunder pulled away late to beat the Los Angeles Lakers 125-107 in a National Basketball Association (NBA) playoff thriller on Thursday, taking a commanding 2-0 lead in their best-of-seven Western Conference semifinal series.

Shai Gilgeous-Alexander, the reigning NBA Most Valuable Player and finalist for the award this season, scored 22 points and the Thunder capitalized on 21 Lakers turnovers to hand LeBron James a defeat in his 300th career playoff game.

Eastern Conference top seed Detroit is also up 2-0 after a 107-97 home win over the Cleveland Cavaliers.

In Oklahoma City, Gilgeous-Alexander was again below his best but he was amply supported.

Chet Holmgren scored 22 points and pulled down nine rebounds, Ajay Mitchell added 20 points and Jared McCain delivered 18 points off the bench to help the Thunder withstand a 31-point performance from Austin Reaves.

James, who became the first player to contest 300 post-season games, scored 23 points and handed out six assists, and the Lakers led by five points early in the third quarter.

But with league-leading scorer Luka Doncic still sidelined by injury the Lakers couldn’t hang on, even with Gilgeous-Alexander on the bench for considerable stretches because of foul trouble.

Oklahoma City produced a 22-5 scoring run to seize control and will aim to keep the pressure on when the series shifts to Los Angeles for games three and four on Saturday and Monday.
