ALEXANDER Klintcharov upset number one seed Akira Santillan in the boys semi-final during the Oceania Closed Junior Championship in Lautoka yesterday.
The close affair was decided following a tie breaker in the second set.
Klintcharov of New Zealand who is ranked fifth in the tournament won 6-4, 7-6 with the tie breaker score at seven.
Santillan of Australia went into the tournament with a world junior ranking of 124 compared to Klintcharov on 240.
The other boys all Australian semi-final between Daniel Guccione and Daniel Nolan was decided after a tiring three-set encounter.
Guccione lost the first set 2-6 but fought back to win the next two sets 6-3, 6-4.
Both the girls semi-finals were all Aussie affairs. Zoe Hives beat Kimberley Birrell 6-3, 6-3 while Priscilla Hon defeated Maddison Inglis 6-2, 6-4.
Tournament referee Patrick O'Rourke said the standard of this year's event was very high.
He said the participation of the top junior players from New Zealand and Australia made it very difficult for the Pacific Island players to progress further in the tournament.
"The tournament has been very good so far and it is of very high standard," O'Rourke said.
"In the girls division the eight seeds are ranked in the top 200 in the world. This made it very tough for the Pacific Island players.
"But some of them have had a good go during their matches.
"They have gained experience. The players from Australia and New Zealand have dominated.
"They are all aiming for the world ranking points. The Pacific Islands are starting with the next generation of kids.
"They have some really good ones in the under-12 and U14 age-groups."
The finals will start at 9.30am at the Construction Hire and Equipment Limited regional courts in Nadovu.
