Oundle have won through to the quarter-finals of the NatWest Schools Under 18 Cup.
They became the first team to qualify for the last eight after a 52-12 win over King’s, Worcester.
Coached by former England international John Olver, the Northamptonshire school must now wait for the quarter-final draw after playing their seventh round match a week earlier than the scheduled date.
Oundle, skippered by Francis Cundell and with a dominant pack powered by identical twins Ben and Tom Curry, were 32-0 up at the break.
Tries came from Ben Curry, Oscar Marshall, Freddie Johnsrud, Angus Wight and Toby Warner (2).
The rest of the points came from the accurate goal-kicking of Angus Mcrae.
Coach Olver said: “It was an outstanding Oundle performance considering we have had no match practice since early December, although with King’s being in the same boat it was an even playing field.
“Some of our offloading was absolutely superb.
“Hopefully with a bit of luck we can get a home draw.
“It’s been a great season. We have won 12 out 15 and are unbeaten since half-term. If we have seasons like that every year I will be a happy man!”
Former champions Whitgift are among the teams attempting to follow Oundle into the last eight.
The draw for the quarter-final will be made live on EnglandRugby.com today (January 29) at 12.15pm.
The quarter-finals are scheduled to be played on February 11.
