Miami at Dallas 9:00 pm EDT NBA Finals Heat lead, 3-2

DALLAS (Ticker) -- Three straight home victories have allowed the Miami Heat to evolve into a confident squad closing in on a championship.

Miami can complete its 18th season by capping an extremely rare comeback to win its first NBA title Tuesday when it visits the suddenly-shaken Dallas Mavericks in Game Six.

Looking to join the 1969 Boston Celtics and the 1977 Portland Trail Blazers as the only NBA champions to bounce back from a 2-0 deficit in the Finals, Miami can give coach Pat Riley his fifth crown and first since 1988 with the Los Angeles Lakers.

The Heat were minutes from losing the first three games of the series to the Mavericks, who seemed to be hitting on all cylinders. However, Miami rebounded from a 13-point deficit to win Game Three, limited Dallas to seven fourth-quarter points in Game Four, and pulled out an overtime victory Sunday.

Dwyane Wade again was the hero for the Heat in Game Five, scoring 17 of his 43 points in the fourth quarter - including the final 11 for Miami in regulation - in Sunday's 101-100 win over the Mavericks.

Averaging 34.4 points in the Finals, Wade forced the extra period by hitting a bank shot with 2.8 seconds to go in the fourth quarter. He added the go-ahead foul shot with 1.9 seconds left in overtime, giving him a Finals-record 21 free throws.

"We took care of business at home like we're supposed to do," Wade said. "But you know, we've got to win one on the road to reach our goal. We've got a challenge ahead of us and I'm excited about this team's chances with the challenge."

In order to claim the NBA's biggest prize, Miami must snap a six-game losing streak at Dallas dating to March 2, 2002. The stretch includes a 112-76 defeat February 9, the Heat's worst loss of the year.

Returning home where they are 8-2 in the playoffs, the Mavs welcome back Jerry Stackhouse after he served a one-game suspension Sunday for a flagrant foul on Shaquille O'Neal in Game Four.

Jason Terry scored 35 points and Josh Howard added 25 with 10 rebounds for the Mavericks in Game Five. The duo combined for 27 of the team's second-quarter points en route to a 51-43 halftime edge. However, neither could make a basket in crunch time.

Dallas superstar Dirk Nowitzki has been limited to 37 percent (31-of-83) shooting from the floor and 21.2 points in the series, a decrease of five points from his regular season average.

The Mavericks, who are also fighting for their first championship, have matched their longest losing streak of the season and must win twice to avoid a total collapse of their early series lead.

"I know our fans are going to be really crazy," Dallas coach Avery Johnson said. "We play pretty good basketball at home. We've got homecourt advantage. So we know we have to play well and win Game Six. There's no tomorrow and I like that no-tomorrow feeling for our team."

If necessary, Dallas will host Game Seven on Thursday.
