SACRAMENTO >> One year to the day when Klay Thompson missed all 10 shots in his final game for the Warriors in a play-in loss in Sacramento the former Warriors star found redemption — and kept alive the Dallas Mavericks’ chaotic season for at least one more game.

Thompson fueled a 120-106 win over the Sacramento Kings on Wednesday night with four 3-pointers in Dallas’ 44-point second quarter. That turned the play-in game into a laugher and helped erase the memories of the Spash Brother’s dud in a 118–94 Warroprs loss to the Kings in the same buidling a year ago.

“Human nature, when you end a season on a sour note like that you want to come out and prove people wrong,” said Thompson, who scored 16 of his 23 points in Dallas’ dominant second quarter. “But I thought I did a good job to start the game of trying to dish, rebound, play defense. The shots came to me after that.”

Dallas advanced to play at Memphis tonight for the chance to get into the playoffs as the eighth seed in the West. The winner of that game will open the playoffs on Sunday at top-seeded Oklahoma City.

As for the Kings, soon after the game, the team and general manager Monte McNair agreed to part ways. A person familiar with the decision said the sides mutually agreed on the breakup.

Thompson, 35, was traded to the Dallas Mavericks in a six-team sign and trade last July after spending his first 13 seasons with the Warriors and making up half of the famed Spalsh Brothers tandem with Steph Curry.

It has been a rough season for Thompson and the Mavericks. Thompson played in 72 games (all starts) but his scoring average of 14.0 points per game was his lowest since his rookie season in 2011-12. He shot a career-worst 41.2 percent from the field, and failed to make at least 40 percent of his 3-point attempts for the third time in the past four seasons.

Dallas played in the NBA Finals against the Celtics a year ago, but barely made the play-in round after trading young superstar Luka Doncic to the Los Angeles Lakers in a seismic trade that brought Anthony Davis to Dallas and vitriol from the fan base to the organization.

Star point guard Kyrie Irving went down with a season-ending knee injury shortly after that trade, ending any realistic hopes of another deep playoff run.

“We’ve had a tumultuous season to say the least,” Thompson said. “The injury bug has struck us like I’ve never seen before. But we’re still here playing postseason basketball. We can really give the city of Dallas some hope, especially if we go to Memphis and repeat this type of performance.”

It was a disappointing ending to an underwhelming season for the Kings, who fired coach Mike Brown in December and traded star point guard De’Aaron Fox to San Antonio in February. It all led to Sacramento missing the playoffs for the 18th time in 19 seasons, raising questions about the team’s future.

“This is where I want to be,” interim coach Doug Christie said. “You guys know that. I need to finish what I started.”
