(My Sportsbook) - Gilbert Arenas and Jason Richardson represented the Golden State Warriors well on All-Star Saturday. Pretty soon, the duo could be starring in the weekend's main event.

Arenas captured MVP honors in the First Act of All-Star Weekend -- the Rookie Challenge. Arenas led the Sophomores to a 132-112 victory by scoring 23 of his 30 points in the second half. Arenas shot 11-of-18 from the field for the game, including 6-of-12 from three-point range.

Richardson, who won last year's MVP honor, poured in a game-high 31 points to tie Kobe Bryant's 1997 Rookie Game record. Richardson also collected six rebounds, five steals and was 13-of-23 from the floor, including 4-of-7 from beyond the arc.

Arenas sank five of his six three-point attempts in the second half to lead a Sophomore comeback. The Rookies led by as many as 15 points early in the second half before the Sophomores used a 28-12 surge to take control of the game. Arenas and Richardson combined to score 42 points in the final 24 minutes.

The Rookies held a 69-57 halftime advantage, but the Sophomores outscored the first-year players 75-43 in the second half.

"We took them light," Richardson said. "They had something to prove. We came out at halftime and we knew we had to play tougher defense."

The only Warrior not to come through in the game was Troy Murphy, who scored only two points and grabbed seven rebounds in 25 minutes for the Sophomores.

There was a bizarre moment for Richardson in the second half, when he pulled a playground move by throwing the ball off the head of Cleveland's Carlos Boozer before draining a three. However, Richardson made up for his goofball antics with a spectacular performance in one of the best dunk contests in recent history.

Richardson captured his second straight crown in the event to become the first player to win back-to-back dunk titles since Michael Jordan (1987, '88).

Richardson's routine was flawless and could have been even more entertaining if the NBA hadn't severely trimmed the event. He capped off the night with his best jam, tossing a lob from the baseline before putting the ball under his legs and slamming left-handed with his back to the basket. The slam earned Richardson a perfect 50, which gave him a 96-93 win over Seattle's Desmond Mason in the finals.

"Yeah, I knew I had it when I threw it," Richardson said. "I knew I could get it. It was a pretty good dunk."
