The 14-year-old from Portsmouth didn’t drop a frame in the group stages of the southern qualifier at Chandlers Ford Snooker Club.
He overcame Kent-based Brandon Nguyen 2-0, O’Shay Scott, from Eastleigh, 2-0 and Dorset nine-year-old Harry Wyatt 2-0.
And he then beat Riley Ellis, from north Wiltshire, 2-0 in the last-four and lost 2-0 to home club player Oliver Sykes in the final.
It’s the second year running that Laxton has reached the last-16 of a national junior tournament.
Last season he went down 4-1 in the first knockout round of the English Under-14 Championship in Leeds to eventual winner Stanley Moody.
The following day, Laxton made it a double celebration.
A record 21 players signed in for the Monday Junior Snooker League at Waterlooville Sports Bar, where Laxton beat Harry Wilson in the final of the traditional trophy-day handicapped knockout tournament.
Finn Kirby defeated Elodie Hall in the Plate final.
Following the knockout, joint club-owner Steve Wilson presented the trophies and medals for the fifth season.
A new league starts next Monday.
Players from the Portsmouth region who will be aged under-14 at the end of the year are urged to enter the qualifier for the English Under-14 Championship at the club on Sunday, November 17.
Entry via the EPSB website costs just £2.
