LAS VEGAS – His tooth hurt, his team went over a month without winning a game and for the first few rounds of Saturday night’s NBA Slam Dunk contest, Michael Jordan just wouldn’t give him a break. But in the end, Boston’s Gerald Green slammed all his problems with a resounding windmill dunk over a table to pull out one of the most lopsided victories in Slam Dunk contest history. Green’s final dunk earned him a perfect 50 from the judges – Kobe Bryant, Dominique Wilkins, Vince Carter, Dr. J and Jordan – and brought the 15,694 fans at the Thomas & Mack Center to their feet. As for the toothache that’s bothered him since Friday. “It’s killing me,” he said. “And we’ve got a West Coast trip next week so I won’t be able to see the dentist until we finish that.” Kapono hits the mark: Jason Kapono’s 3-Point Shooting Contest started a lot like his NBA career: a couple clanking off the rim, one air balland then lights-out. The fourth-year pro put an exclamation point on his breakout year – Kapono leads the NBA in 3-point shooting percentage at 56 percent while averaging 11.1 points for the Miami Heat – by besting Gilbert Arenas and defending champion Dirk Nowitzki in the 3-point shooting contest. “I had an air ball or two. I kind of heard the crowd saying, `What the heck is this guy doing out there?’ ” the former UCLA star joked. “I felt pretty good after the first round.” 160Want local news?Sign up for the Localist and stay informed Something went wrong.

You’re all set! “I’m the undefeated, undisputed champion of the world,” Green screamed after dethroning Knicks’ diminutive guard Nate Robinson in the finals. “I’ve never lost a dunk contest.” The 20-year-old guard led this one from start to finish, earning the highest score in every round of the competition. He started the night with a high-flying two-handed dunk off an alley-oop pass off the side of the backboard from teammate Paul Pierce. His second dunk paid homage to Dee Brown, the only other Celtic to win the dunk competition. Green changed into white Reebok pumps, pulled off his jersey to reveal Brown’s No. 7 jersey and jumped over the 5-foot-9 Robinson and slammed it home with one hand while covering his eyes with the other arm. “I wanted to show the respect and do everything the way he did it,” Green said. “(Brown) went down and pumped his shoes up, and I tried the best to use his dunk in a different kind of way.” His third dunk came off another alley-oop from Pierce, this time from behind the backboard. The fourth dunk – a windmill over the table – was a bit anticlimactic because Robinson missed nine straight times before landing a one-handed spin move off the backboard. Green said he hoped his win in the dunk contest would fire up the Celtics’ faithful, who have stuck with the team through its franchise-record 18-game losing streak, which ended Wednesday with a victory over the Bucks.
