LeBron James quickly spun around Trevor Ariza and took off for what he thought would be an easy scoop layup. Nene met James mid-flight, however, and slapped the shot hard against the backboard, sending the four-time NBA MVP crashing into the basket stanchion and delivering a message to the Miami Heat that the Washington Wizards weren't going to be as hospitable as President Obama was at the White House a day earlier. The Wizards, in fact, were quite rude hosts, with Trevor Booker running over and flattening Dwyane Wade in the second quarter, when Washington built a stunning 34-point lead. With a determined and at times dominant effort, the Wizards finally claimed the home victory they have long sought in 2014, relying on that first-half cushion to pull out a 114-97 win over the two-time defending champions. “They came here, whatever. They went to the White House, whatever. We just came here to play," Nene said after scoring 19 points with a career-high nine assists and three blocked shots. John Wall scored a team-high 25 points and also added nine assists as the Wizards (18-19) snapped a four-game home losing streak. With the Heat making one final run to get within nine with 5 minutes 32 seconds remaining, Bradley Beal made a layup. Then Wall closed the door with two free throws, two pretty passes — he found Martell Webster for an alley-oop lob and then fed Nene for an emphatic dunk over James — and a couple of shots of his own. He hit a pull-up jumper over Heat guard Norris Cole, then buried a fall-away three-pointer to end any suspense. With the first sellout crowd of the season on its feet, Wall lifted his hands and motioned for more noise — and it kept coming. “Last four or five games, we was getting blew out by 20 points, so [there] was no point it getting like that,” Wall said of the enthusiastic crowd after the Wizards improved to 8-9 at home. “When you play teams like that, got star players that are on the other side, they’re very excited. But when it’s a game that we can win, the crowd gets into it. We wanted to give them what they deserve, winning games at home.” Nene missed the first meeting between the teams in early December with a sore right Achilles' tendon but relished his big performance and even bigger dunk on James.
