SACRAMENTO, Calif. — For one day at least, the off-court acrimony over a decision not to build a new arena was put aside by Sacramento Kings fans.

Despite anger over Friday’s announcement by Kings ownership that the arena plans were shelved, a near-sellout crowd showed up at aging Power Balance Pavilion on Sunday and was sent home happy by Marcus Thornton.

Thornton scored 20 points and made the winning jumper with 3.4 seconds left, lifting the struggling Kings to a 104-103 victory over the Portland Trail Blazers.

The Kings rallied from a 10-point deficit in the fourth quarter to snap a seven-game skid with only their third win in 15 games.

It was the first home game in Sacramento since the Maloof family announced at the NBA owners meetings that they were backing out of a proposed downtown arena plan in Sacramento.

Since announcing their decision, the Maloofs have been under sharp criticism from Sacramento Mayor Kevin Johnson, local business leaders and angered fans, who still showed up for the mid-afternoon game. Attendance was 16,012.

“We had a few (fans) that may have voiced their opinion, but once the game started going and became an excitable game, I think they fell back to the side,” Kings coach Keith Smart said. “People get upset, but they are die-hard Kings fans. They like Kings basketball, it’s just that they are a little heart-broken, like everyone is right now.”

A reliable clutch shooter this season, Thornton said he was Smart’s choice to take the winning shot. Following a timeout, Thornton came off a pick from DeMarcus Cousins and was surprisingly wide open. He swished a 17-footer off an inbound pass. Portland’s Raymond Felton raced up court and missed a desperation shot from halfcourt at the buzzer.

“I was stunned how open I was,” said Thornton, who went four of five from the floor in the fourth quarter for eight points. “I got to my spot, got the space I needed, and shot it. Thank God it went in.”

Cousins scored 19 of his 23 points in the second half and also had seven rebounds. The second-year center had been in a recent scoring funk the past six games after going for a career-high 41 points in an April 3 loss to Phoenix.

“It took a while, but it feels good to get a win,” Cousins said. “Even with all the drama going on, our fans came out and supported us, stayed engaged in the game and showed their loyalty toward us. So we’re thankful to have them and we love them for it.”

Tyreke Evans also had 20 points for the Kings, and Isaiah Thomas had 18 points and eight assists.

Wes Matthews made a career-high eight three-pointers and scored 31 points for the Trail Blazers, who made 16 of their 32 three-point attempts. His biggest shot appeared to have given the Blazers the victory.

After a steal by Terrence Williams gave the Kings the ball, Cousins drove the baseline on Joel Przybilla and made a difficult left-handed shot from close range. However, Matthews quickly answered, getting free of Francisco Garcia for a corner three-pointer, giving the Blazers a 103-102 lead with 5.8 seconds left.

“I wasn’t going to pass it out, I had to take that shot,” said Matthews, who made seven second-half three-pointers, a Sacramento arena record for a half by an opposing player. “I didn’t really want to take a shot as early as I did, but Garcia jumped on my right hand. My favorite shot is a step-back so he gave it to me.”

Felton scored 19 points, Nicolas Batum had 14, and JJ Hickson added 10 points and 13 rebounds for Portland.
