Dwyane Wade tried, playing with a rejuvenated hop in his step. LeBron James tried, filling the box score through three periods. Chris Bosh tried, coming alive with a third-quarter scoring burst.

And, still, the Miami Heat needed more against a Milwaukee Bucks team that decided to this time make it a game.

Enter Chris Andersen and Norris Cole.

Exit the Bucks.

Perhaps never to make it back to South Florida this season.

Sparked by Andersen and Cole at the start of the fourth quarter, the Heat turned a close game into a 2-0 series lead with a 98-86 victory Tuesday night over the Bucks at AmericanAirlines Arena.

The series' next two games are in Milwaukee.

Up by three heading into the fourth quarter, unable to push ahead by more than eight to that stage, the Heat opening the final period with a 12-0 run that began with an Andersen 3-point play and was capped by a Cole 3-pointer, accomplished over a frenetic 2 minutes, 23 seconds.

From the outset, it was clear this would not be a repeat of the Heat's 100-87 Sunday victory in the opener of this best-of-seven first-round NBA playoff series.

In that game, it was all or nothing for the Bucks when it came to guards Brandon Jennings and Monte Ellis, who combined for 48 points.

This time, neither scored a basket in the first half and neither was a factor, Jennings going from 26 points in the opener to eight this time, missing his first seven shots. Ellis, who scored 22 in the series opener, this time closed with seven.

Instead, it was Bucks forward Ersan Ilyasova overcoming his 1-of-7, two-point performance in Game 1 to go for 21 points on 9-of-14 shooting. It was center Larry Sanders overcoming early foul trouble to make his first five shots and close with 14 points on 6-of-7 shooting before sustaining a late injury, a collision that sent Heat forward Shane Battier to the locker room.

James paced the Heat with 19 points, eight rebounds and six assists, after closing two assists of a triple-double in the series opener. Wade added 21 points and Bosh 10.

But what the Heat needed after three sluggish opening periods loaded with turnovers and missed 3-pointers was a power surge.

Enter Andersen and Cole, who raised the volume at the start of the fourth quarter, giving the Heat a lead that history shows may be just about impossible for the Bucks to overcome.

Andersen finished with 10 points and six rebounds, Cole with seven points.
