Miami, FL (SportsNetwork.com) - John Wall and the Washington Wizards added to the Miami Heat's early season misery at home.

Wall had 20 points and 10 assists as the Wizards defeated the Heat 105-103 on Friday night.

Dwyane Wade knocked down a straightaway 3-pointer off an inbounds pass with 16.7 seconds left to claw Miami within 101-100.

Bradley Beal sunk a pair of free throws at the other end and then came up with the game-clinching steal. The Wizards double-teamed Wade right as he crossed the halfcourt line and Beal came up with the swipe before hitting two more free throws to seal the outcome with 3.8 ticks left.

"Just shows our resilience not to quit," said Wall. "In the fourth quarter, we got stops and worked out way back in the game."

The Heat lost their fifth straight at home for the first time since March of 2008 and have dropped eight of their last nine in South Beach overall.

"It's tough to lose," Miami coach Erik Spoelstra said. "It really came down to them making plays."

Nene posted 20 points and six rebounds, while Beal added 16 points and seven boards for the Wizards, who have won six in a row.

Wade finished with 28 points and eight assists for Miami, which fell to 4-9 at home on the year. The Heat had lost just 13 games over the last two years at American Airlines Arena coming into the season.

Miami was without Chris Bosh for a fourth straight game due to a calf injury.

Wall netted half of his point total in the fourth quarter. His up-and-under reverse spun out, but Paul Pierce was there to tip it home and stake the Wizards to a 97-95 advantage with 1:32 to play. Wall then hit a pull-up jumper from the top of the key on Washington's next trip up the floor to put it up four.

Wade got his floater to drop at the other end before Wall split a pair of foul shots to make it 100-97 with 33.8 ticks on the clock. Wade was unable to get his ensuing shot to go, however, and Wall again made 1-of-2 from the stripe to extend the visitors' lead to four.

Earlier, Wall nailed a step-back jumper at the first-quarter buzzer to give Washington a 29-25 lead going into the second.

Mario Chalmers put in the final five points of a 9-2 Heat run during the middle stages of the second, including a triple to cap it and tie the game at 47-47 with 4:53 to go in the period.

Miami, which shot a season-best 64.7 percent (22-of-34) in the first half, took a 55-54 edge into the locker room.

The Heat were up 79-76 after three.
