After defeating Australia in an exhibition game two days earlier, Team USA blew a 10-point third quarter lead in a 98-94 loss to the Boomers on Saturday at Marvel Stadium in Melbourne.
It was the first loss for the United States in a major international tournament or exhibition since the 2006 FIBA World Championship semifinals against Greece.
“They wanted it more than us tonight. Lesson learned for us,” Walker said after the game.
Team USA will travel to Sydney for an exhibition game against Canada on Monday.
