Patty Mills hit a 3-pointer as time expired, giving Australia an 87-84 win over Argentina in a pre-Olympics exhibition on Saturday night. Mills inbounded the ball with 2.5 seconds left to Jock Lansdale, who handed it back to Mills for the winning shot at the buzzer — capping a comeback that was needed after the Australians wasted a 10-point lead midway through the final quarter. Mills had 17 points for Australia, which got 16 from Joe Ingles, 15 from Matisse Thybulle and 14 from Aron Baynes.
