Holders United States and dark horses Slovenia eased into the basketball World Cup knockout stages with two games to spare but eastern European giants Lithuania left themselves with work to do after a surprise defeat by Australia on Tuesday. Unfancied Ukraine produced the day's other upset with a 64-58 defeat of Turkey while the Dominican Republic boosted their own hopes after a 74-68 success against Finland. The Americans looked a little fazed as New Zealand's Tall Blacks performed their traditional pre-game haka, but showed no nerves in a one-sided contest as Anthony Davis led the charge with 21 points and nine rebounds in a 98-71 rout.
