MINNEAPOLIS — Shai Gilgeous-Alexander's goal was to play a better all-around game. He did that and then some.

The Canadian had 20 points, a career-high 20 rebounds and 10 assists in his first triple-double, leading the Oklahoma City Thunder to a 117-104 victory over the Minnesota Timberwolves on Monday night.

“Coach had challenged me before the game to fill up the stat sheet more and do more things,” Gilgeous-Alexander said. “Because he thought, as well as myself thought, that I was more capable of what I was doing.”

The Toronto-born Gilgeous-Alexander came in averaging 23.7 points in his previous 13 games but did much more than score in this one, also matching his career best in assists. He became the youngest player in league history to record at least 20 points, 20 rebounds and 10 assists in a game.

“He's tough. He's very tough,” Minnesota's Andrew Wiggins said. “He's a big guard that can put it on the floor and create for others, and he's a bucket. He can make a bucket when he needs to.”

Gilgeous-Alexander is the fourth second-year player in NBA history to register a 20-20 triple-double. He joins Shaquille O'Neal, Charles Barkley and Oscar Robertson. The only other guard to have a 20-20 triple-double in the last 30 seasons is former Thunder star Russell Westbrook.

That after Gilgeous-Alexander did not record an assist in 35 minutes against the Lakers on Saturday.

“I just felt like we were on our heels a little bit in the previous game against the Lakers," Gilgeous-Alexander said. "That was one of the things that Coach mentioned to us, attacking first. I felt we did that as a group. When you attack as a group, you get more comfortable faster.”

Danilo Gallinari scored 30 points for the Thunder, who have won 12 of their past 15 games and six of seven on the road.

Naz Reid scored 20 off the bench for Minnesota, which was still without Karl-Anthony Towns. Reid has scored in double figures in six of the last eight games. Robert Covington scored 18 points.

The Thunder held a 63-60 lead at halftime. They went on an 11-2 run early in the third quarter and then a 10-3 burst midway through the third to push their lead into double figures. Oklahoma City led by as many as 18.

“I thought the third quarter for us was important,” Thunder coach Billy Donovan said. “We had some action, had some really good ball movement, had some great clips offensively. I thought that was critical.”

Steven Adams had 13 points, 11 rebounds and five assists for the Thunder.

Shabazz Napier scored 16 points for the Timberwolves. Rookie Jarrett Culver scored 14 points.

“We obviously need more from everybody when we have guys that are out who are big parts of this team," Minnesota coach Ryan Saunders said. "I was happy with some of the guys.”
