It was the third time in four games that Bosh has scored more than 20 points.
It was also a season high in points for the Heat.
The Heat (20-6) have won six of their past seven games, including 4-0 on this homestand that concludes Monday against Atlanta.
In its series against the Kings, Miami has won 10 in a row overall and 12 consecutive at home. The Heat have not lost to the Kings since 2008 and have not lost a home game to Sacramento since Nov. 10, 2001.
Meanwhile, the Kings (7-18) are in 14th place out of 15 teams in the Western Conference. They have lost five out of their past six games, including all three in a road trip that ends Saturday in Orlando.
The Kings never threatened the Heat after that.
NOTES: Heat G Ray Allen dunked twice in the first half -- his first two of the season. ... The Kings' hopes for a franchise turnaround are pinned on three young and talented players: C DeMarcus Cousins, 23, SF Rudy Gay, 27, and PG Isaiah Thomas, 24. But the Kings don't have a standout at power forward, rank third from the bottom in the league in points allowed and are still waiting for a shooting guard to emerge -- either rookie Ben McLemore or third-year pro Jimmer Fredette. McLemore, the seventh pick in the draft, starts and averages 8.9 points on 35.5 percent shooting from the field. Fredette, the 10th pick in the 2011 draft, is a reserve averaging 4.7 points and shooting 39.6 percent from the floor. ... The score-tying 3-pointer made by Heat F Chris Bosh with 90 seconds left in Wednesday's win over Indiana broke a streak in which he had missed 15 straight shots from beyond the arc. ... Heat F Michael Beasley (hamstring) has been out since Dec. 5. ... The Kings and Heat have a rematch next Friday in Sacramento.
