Wizards guard Gilbert Arenas is ready to do almost anything to make the U.S. national team, starting with mastering the shorter 3-point shot.

"I've been working out on the international 3, it's like a free throw now," Arenas said Tuesday at an open workout before leaving for next week's training camp.

Arenas and 22 other invitees will train at the camp run by U.S. coach Mike Krzyzewski in Las Vegas from July 19-25. Those who make the final roster will play in this year's world championship in Japan.
