Thomas Sharp’s eight-match unbeaten run since making his competitive debut in the Waterlooville Sports Bar Junior League is over.
The Portsmouth 12-year-old finally lost to Callum White – the Cuestars South of England Under-21 Bronze Tour championship play-off winner.
Sharp did have the consolation of recording his highest break of 15 against Antony Terroni.
Harry Wilson inflicted a rare defeat on champion-elect Samuel Laxton and the 11-year-old went on to win the top group.
Laxton leads Dean Russell by 22 points with six weeks left.
World Snooker coach Tim Dunkley runs sessions for under-19s from 4.30pm to 6.30pm every Wednesday.
The league runs throughout the summer as usual.
A second junior league will be launched at the same time on Mondays from September.
