The Ballincarrow brawler defeated African champion Hichem Maouche of Algeria in the quarter-finals of the under-18 tournament in Argentina.
Clancy made a sharp start, taking the first round only for Maouche to come back strong in the second. Needing a big final round, Clancy swept the third to ensure a unanimous decision win and a semi-final berth.
The European Youth and Junior silver medallist, who is still in his first year at Youth level, will now rematch Great Britain’s Hope Price in the semis in a repeat of their European final earlier this year.
Since that win for Price, the English teen has gone on to win World Youth silver – where he lost to American Asa Stevens in the final who had previously defeated Clancy in the same tournament.
This bout is scheduled for tomorrow afternoon.
While he has made it to the Last Four, the Yeats County teen is not guaranteed a medal – but he does have two chances of securing one. Should Clancy win his semi, he will be guaranteed a silver and will box for gold in the final.
If he loses, Clancy will enter into a box-off with the other losing semi finalist for the one bronze medal on offer – with the Youth Olympics being different to all other major international competitions which reward both losing semi-finalists with bronze.
