LeBron James and Chris Bosh each scored 28 points, and the Heat made it 21 straight wins, beating the Bucks 107-94 last night in Milwaukee.
Just three other teams have won 20 in a row in one season, and the Heat now trail just the 1971-72 Los Angeles Lakers (33) and the 2007-08 Houston Rockets (22) after moving ahead of the 1970-71 Bucks.
They withstood an early scare when Dwyane Wade walked to the locker room with a neck strain after crashing to the court. Miami led by as much as 17 in the third quarter, then withstood a push by the Bucks to remain unbeaten since a loss at Indiana on Feb. 1.
Miami next plays tomorrow at Toronto, where the winning streak began on Feb. 3.
Bosh hit from all angles and was 12 of 16 in the game, nailing two 3-pointers. He even converted a four-point play that made it 67-53 about five minutes into the third quarter.
James was his usual dominant self, and Wade finished with 20 points as the Heat avenged a loss at Milwaukee in late December.
Ersan Ilyasova led Milwaukee with 26 points and a season-high 17 rebounds. Brandon Jennings scored 21, but the Bucks shot just over 37 percent.
Lakers 99, Pacers 93
In Indianapolis, Kobe Bryant lasted just one quarter on a severely sprained left ankle, then watched Dwight Howard complete a go-ahead, three-point play with 90 seconds left to help hold off the Pacers.
Bryant started two nights after he was hurt, but was ineffective. He went 0 for 4 in the first quarter, then went to the bench and did not return. He spent the second half holding a black box with wires running down to the injured ankle as he cheered on the Lakers (35-32).
Bryant is known as a remarkably quick healer who hasn’t missed a game since the 2009-10 season.
Howard finished with 20 points and 12 rebounds. Metta World Peace had 19 points.
