Gilbert Jay Arenas Jr. (/əˈriːnəz/; born January 6, 1982) is an American former professional basketball player. Arenas attended Grant High School in the Valley Glen district of Los Angeles, and accepted a scholarship offer to the University of Arizona late in his junior year. He entered the 2001 NBA draft and was selected in the second round (31st pick) by the Golden State Warriors.
Arenas is a three-time NBA All-Star, three-time member of the All-NBA Teams, and was voted the NBA Most Improved Player in the 2002–03 season. Arenas was nicknamed "Agent Zero", due to his former jersey number and his late-game shot-making ability. He also was nicknamed "Hibachi", a nod to the small Japanese barbequing device, which literally translates to "bowl of fire." Both names quickly became fan favorites during his time in the Washington, D.C. area. He has also been nicknamed "Gibby."
Arenas was suspended for most of the 2009–10 season because of handgun violations stemming from an episode on December 24, 2009, and for subsequent actions that appeared to make light of this episode.
