MIAMI -- Chris Andersen scored eight points off the Miami bench in the fourth quarter to keep Milwaukee at bay and boost the Heat to a 98-86 victory in Game 2 of the Eastern Conference playoff series on Tuesday night in AmericanAirlines Arena.
The win gave the top-seeded Heat a 2-0 lead over the eighth-seeded Bucks in the best-of-seven series and raised their home record to 39-4 this season.
Leading by a slim 68-65 margin to start the fourth quarter, the Heat opened with 12 straight points that included a three-point play by Anderson and the Miami defense forcing turnovers on consecutive possessions.
LeBron James, who scored 19 points, knocked down a bucket before Norris Cole made two free throws during the sequence. Andersen followed with a layup and Cole hit a shot from behind the arc as the Heat opened an 18-point lead, its largest of the game.
Dwyane Wade led the Heat with 21 points. Five Miami players scored in double figures.
Ersan Ilyasova paced the Bucks with 21 points, with 14 coming in the first half.
In the third quarter, Chris Bosh scored eight points as Miami built up a 68-60 advantage with 2:03 to go before the Bucks closed the quarter with a flurry. Bosh had just two points to that point.
Milwaukee's Larry Sanders, who missed four games with a back injury before scoring six points in Game 1, had eight in the third quarter and teammate Brandon Jennings scored seven, including a fast-break layup, to pull the Bucks to 68-65 at the end of the quarter.
In the first half, Milwaukee's starting backcourt was held to one point -- a Jennings free throw -- and no baskets until Monta Ellis' layup with 8:23 left in the third quarter.
With the score tied at 33 in the second quarter, Miami went on a 14-10 run to end the half despite going more than four minutes without a field goal.
James, Wade and Mario Chalmers combined to go 15 of 19 from the field in the first half and the rest of the team was 3 of 17.
Early in the first quarter, Milwaukee led by as many as five points as the teams combined to turn the ball over nine times. In one sequence, the Heat lost it on three consecutive possessions.
Ilyasova connected on four of his first six shots from the field and had 12 points in the first quarter for the Bucks.
Trailing 18-13, Miami outscored Milwaukee 12-5 in the final 4:15 of the quarter to take a 25-23 lead.
Marquis Daniels scored eight points off the bench for the Bucks in the second quarter after he finished Game 1 with two points.
