OKLAHOMA CITY — Shai Gilgeous-Alexander delivered 31 points, leading the Oklahoma City Thunder to a 112-105 victory over the Denver Nuggets on Tuesday night, advancing their lead to 3-2 in the Western Conference semifinal series.

Oklahoma City overcame a 44-point, 15-rebound night from Denver’s Nikola Jokić.

The Thunder can clinch the series on Thursday in Denver.

Gilgeous-Alexander made 12 of 23 field goals and bounced back from a slow start to lead six players in double figures.

“What the great players do is they rise in the face of those challenges and adversities,” Thunder coach Mark Daigneault said. “And I just thought he got more and more composed as the game went on. And despite the fact that the pressure was mounting and it got hotter in there, he got cooler and just kind of settled into it, made the right plays, let the game tell him what to do.”

Jokić made 17 of 25 shots.

Denver’s Jamal Murray scored 28 points, but he made just 10 of 27 shots.

No other Denver player scored more than 13 points.

“This is a really disappointing loss,” Denver interim coach David Adelman said. “The guys in there should be disappointed. It’s a heavy loss and we have to bounce back quickly to win Game 6 and give ourselves a chance to come back, have a game like this, but finish it.”

Oklahoma City ran out to a 12-2 lead, and it looked like it might turn out like the Thunder’s blowout victory in Game 2.

Denver made one of its first nine shots, and that was a putback by Jokić.

Denver rallied and led by 11 in the second quarter, but Oklahoma City closed strong and trailed 56-54 at halftime.

Jokić had 19 points and nine rebounds before the break.

Murray scored 13 points in the third quarter and Jokić added 12 to help the Nuggets take an 86-78 lead into the fourth.

Still, there were missed opportunities.

“It felt like every time we had a chance to go back up 12, or get it back at 14, we wouldn’t make the shot and they’d run out and make a basket or score in transition,” Adelman said. “So it compounded itself.”

Oklahoma City’s Lu Dort, who scored three total points in the first three quarters, hit a trio of 3-pointers in a two-minute span to cut Denver’s lead to 92-90 midway through the fourth.

Jokić hit a deep fadeaway 3-pointer to tie the game at 103 before Oklahoma City closed it out.

Jalen Williams’ 3-pointer with 1:18 remaining gave the Thunder a 106-103 lead, and Gilgeous-Alexander’s three with 48 seconds to go pushed Oklahoma City’s lead to six.

“I thought we executed as well as we have in the playoffs down the stretch in a close game,” Daigneault said.
