London Irish are showing no signs of slowing down as they managed to preserve their unbeaten Southern Conference record in this year’s Premiership Rugby Under-18 Academy Competition with a 38-10 victory at Bristol Rugby.
Will Attfield crossed for a try-double while Jack Cooke, Rory Brand, Harry Butler and Tom Parton joined him on the Exiles scoresheet.
It handed Irish their fourth bonus-point victory in five games, and means they will be competing for the trophy outright on Finals Day later this year.
Second-place Wasps were handed a setback by Harlequins, who managed to shut them out in a gritty 15-0 win.
James Gulliver went over off the back of a driving maul in the only score of the first half before Harlequins cranked through the gears. A Max Coyle try, along with five points from the boot of Marcus Smith sealed a Harlequins victory for the second time in the competition this year.
Wasps' loss was Saracens' gain, as they moved to within three points of second following a 20-13 triumph over Exeter Chiefs.
Ben Earl, Will Kaye and Tom Ffitch – who also booted a penalty and conversion – were the Saracens' try-scorers, while Sam Daly's effort and Harvey Skinner's eight points did not prove enough for Exeter.
In the Northern Conference, an impressive Worcester Warriors soared to their fourth victory from six games after putting Newcastle Falcons to the sword 26-0.
Both sides found the going tough in the first half, though Blake Edwards' converted try nosed Worcester in front. Alex Hearle got the second but it took two efforts in the last five minutes – from Tom Dodd and Jack Helme – to grab the bonus-point win and boost Worcester's chances of reaching Finals Day.
Levi Davis notched a try-double in the only other Northern Conference fixture over the weekend, as Leicester Tigers secured a 28-12 win at Yorkshire Carnegie.
Toby Hutchinson and Sam Grahamslaw also crossed for Tigers, who need a final win over Newcastle Falcons next weekend to secure their own place at Finals Day.
