The Tournament Referee had to intervene to solve an unusual dispute in one of yesterday's boys singles quarter-finals at the House & Stock Self Storage Belfast City ITF junior tournament at Windsor.
The sole Irish survivor, top seed Osgar O'Hoisin, eventually defeated Briton Lucas Percy 6-2 6-3 to book his place in today's semi-final against American Vuk Budic.
But the referee had to step in after the players failed to agree on the score with Percy serving at 2-3 down.
Tournament Referee Ugo Lopez ruled that play should resume with Percy serving at 40-15 although O'Hoisin insisted the score was, in fact, 30-15.
After a delay of some 10 minutes, Percy held his serve to draw level but the drama didn't end there as the Irishman recovered to stage a stirring comeback.
O'Hoisin was 4-3 up and 0-40 down on his opponent's serve but he won the next four points and then served out for the match.
The other semi-final is an all-British affair between Ewan Moore and Luke Hammond.
