Courtney Williams took over in the second half, scoring 18 of her game-high 20 points, and the Lynx rallied without injured star Napheesa Collier to beat Las Vegas 76-62 Tuesday night at Target Center.

“She put the team on her back with Phee out,” coach Cheryl Reeve said.

With the win, Minnesota (11-1) will host the Commissioner’s Cup championship game on July 1 against Indiana. The Lynx beat New York in last year’s title game of the WNBA midseason tournament.

But of larger concern for the Lynx could be Collier, who left early in the third quarter with a back injury and did not return. There was no update postgame.

Diamond Miller and Natisha Hiedeman each scored 12 points off the bench, and starting center Alanna Smith finished with 10 points and a season-high 13 rebounds.

For Miller, the performance has been a long time coming.

The No. 2 overall pick in the 2023 draft, she was named to the All-Rookie Team but has battled injuries since. She played in just 21 games last season and has been a single-minutes player much of this season, if she gets in at all.

“I’m just a fighter. I’ve gone through a lot of stuff,” she said while fighting her emotions. “This moment means a lot to me, because it took a lot to get this. I’ve worked really hard, and sometimes things don’t happen as quickly as you want, and God makes you wait.

“It’s really hard to be in my situation where you don’t know what’s going to happen from game to game and still being resilient to be ready for your moment. And today I was.”

Williams couldn’t help but smile talking about her teammate.

“I’ve been telling her since the game was over that I’m so proud of her because we see the work that Diamond has put in. … She was huge. She gave me that boost that I needed.”

Down by 14 in the first half and nine at the break, Miller scored seven points in the third quarter as the Lynx took over, including a step-back 3, and trash-talking Chelsea Gray with a hand gesture after a basket that she’s too small.

She was also solid on defense. “I just love playing basketball no matter what, good days, bad days, being on the court is just something that I live for,” Miller said.

“We needed that extra energy today, and that’s exactly what Diamond brought. Honestly, that’s the reason we won this game,” Hiedeman said.

The Lynx doubled up Las Vegas 46-23 in the second half.

Up 56-52 to begin the fourth quarter, Williams scored 11 of Minnesota’s points in a 14-2 run to put the Lynx up by 16. Her final two buckets came via a floater in the lane and a 3-pointer.

The guard was 1 of 6 from the field and a minus-18 in the first half. She finished 8 of 23 and a plus-4.

“Courtney has a very, very special way about her. She never believes that she’s out of it,” Reeve said.

Losing for the fourth time in five games and again playing without reigning Most Valuable Player A’ja Wilson (concussion protocol), Las Vegas (5-6) turned the ball over 21 times, leading to 27 Lynx points.

The Aces, who led by nine at intermission, missed nine shots and had four turnovers in an 8 minute, 20 second stretch over the third and fourth quarters.
