SACRAMENTO, Calif. (AP) -- DeMarcus Cousins had 29 points, 10 rebounds, five steals and four blocks, and the Sacramento Kings dealt a blow to the Washington Wizards' playoff hopes with a 120-111 victory on Wednesday night.
The Wizards dropped their second straight and fourth in five games, falling 3 games behind Indiana for the eighth and final playoff berth in the Eastern Conference.
Bradley Beal scored 24 points and Otto Porter had 20 for the Wizards. John Wall contributed 14 points and 13 assists, and Markieff Morris had 13 points.
Rudy Gay and Omri Casspi scored 15 points apiece for the Kings and Rajon Rondo had 15 points and 11 assists before he was ejected after getting a double technical in the closing seconds of the game. Darren Collison had 13 points and Kosta Koufos 12.
The victory was the third straight at home for the Kings and gave them their first 30-win season in eight years.
However, the Kings will miss the playoffs for a 10th straight season.
Cousins got off to a great start in the opening quarter, scoring 11 points in seven minutes. He had been outplayed by Marcin Gortat in a loss earlier this season when the Washington center had a season-high 27 points and 16 rebounds.
Cousins hit consecutive baskets to increase the Sacramento lead to 112-97 with a little over 3 minutes left in the fourth quarter.
He also received his 16th technical of the season in the closing seconds, which will trigger an automatic suspension for Friday's game if it is upheld.
Koufos scored seven straight points early in the fourth quarter. A 3-pointer by Ben McLemore put the Kings ahead 108-95 midway through the fourth.
Wizards: Porter scored 13 points in the third quarter.
