 The U.S. men's basketball team enjoyed another successful Olympic tune-up. A big second-half lead was just enough for the U.S. to defeat Australia Monday, 98-92. In their five-game exhibition schedule, the Americans are now 2-0. They were up by 24, saw the lead sliced to four in the final minute, but a couple of three-pointers by Tyrese Halliburton kept the U.S. out of harm's way.
