Brazil and Argentina kept alive their dreams of rekindling past glories after winning in contrasting fashion to reach the basketball World Cup last 16 with a match to spare on Wednesday. Australia and Lithuania also booked their knockout-stage berths on a frantic penultimate day of the preliminary group stage, with holders United States and hosts Spain enjoying comfortable wins after sealing their passage earlier. Winners in 1959 and 1963, Brazil stayed on course for a first podium finish since 1978 with a rollercoaster 81-73 win over Serbia, having trailed in the second half after squandering a 16-point halftime lead. Argentina, the 2002 tournament runners-up and the 2004 Olympic champions, romped to an 81-46 mauling of surprise package Senegal on the back of 22 points and 14 rebounds from Indiana Pacers forward Luis Scola.
