Belgrade, Serbia, August 10.— United States of America will play Croatia in the quarter-finals of the FINA Junior Men’s World Championships at the Sports Centre Milan Gale Muskatirovic here on Friday.

John Hooper claimed four of the goals — three in the final quarter — as USA swept aside Canada 14-4 to earn the encounter with Group B winner Croatia, who had a rest day.

The second team to the quarters was Spain with a tsunami of goals against China, finishing 27-5, all field players scoring for Spain. The best were Alex de la Fuente and centre forward Roger Tahull, who scored the last four goals inside three minutes.

Italy gained the better of Russia 10-7 after winning the second period 3-0 and pulling away in the second half thanks to all-round teamwork and despite a red card against Giacomo Cannella midway through the fourth.

The last quarter-finalist was Montenegro, downing Australia 16-5 with hard-pressing water polo in the early stages to race out to a 4-0 lead and on to victory.

In the round 13-20, Iran collected its first win with a 14-9 margin over South Africa, leading 6-0 at halftime. Jason Evazard top-scored with four goals as South Africa awoke and won the second half 9-8. Netherlands sent off New Zealand 14-4 in a match of red cards and multiple exclusions. Egypt controlled Puerto Rico for a 10-6 win in an engrossing match where the smaller Puerto Ricans defended brilliantly against heavier odds. Japan closed the group with a handsome 23-8 defeat of Argentina, Kiyomu Date netting five from five attempts.

In Friday's classification semifinals for 13-16, Japan will play Egypt and Iran will clash with Netherlands. In the classification 17-20 semifinals, South Africa plays New Zealand and Puerto Rico faces Argentina.
