From the restart Wasps again went at Gloucester, testing their defensive metal. The hosts then countered again from a turnover at the scrum through back row Gareth Jones.
This field position soon lead to Gloucester's second try, when second row Joe Batley, who was outstanding throughout, found space from a quick tap penalty, with Evans once again adding the extras, stretching Gloucester's lead to 14.
The next 15 minutes saw Gloucester's talented back line stretch the Wasps defence, showing good ambition to run from deep, with Lloyd Evans taking firm control of the Cherry and White's attack, using strong runners Robson Skipsey, Harry Priestner and Elliot Creed to gain momentum.
This field position set up a platform for the forwards to drive the Wasps pack over from close range to give Underhill his second score of the afternoon. Again Evans adding the conversion to make it 21-0 to Gloucester at half time.
Gloucester started the second half as they finished the first with Priestner breaking the line and offloading well, only for the move to be stopped a metre short.
Their defence was then tested when 20 minutes of continuous pressure forced Gloucester to defend a series of catch and drives, and a bombardment of their try line with Wasps several times getting over the white wash, but unable to ground the ball. The pressure finally told, and Wasps went over for their opening score of the game.
Gloucester soon regained ascendancy from the restart, holding good field position and putting together a series of well constructed multi phase attacks.
They finally picked their moment, when back row replacement Jordan Hancock made the most of a mismatch in the defensive line, making an outside break to run a try in from the Wasps 22. Lloyd Evans impeccable kicking form continued to restore the home side's lead to 3 clear scores making it 28-7.
There was still time for one more score, and it came when another strong run from Creed produced quick front foot ball for the Gloucester scrum half Farrell Gwillam to find prop Will Goodrick-Clarke who went under the posts for the game's final score.
Evans kept his kicking percentage at 100% to make the final score Gloucester 35, Wasps 7.
Gloucester Academy Coach Simon Lane said:
"The team featured a mixture of U16 and U17 players from our Junior Academy, with a number of players away with U16 international commitments and injury. But it is a promising sign of things to come as we build toward next season's U18 Academies League.
"Pete Buxton and Geraint Davies who coach the age group are really getting the best out of the boys and are both excited about the quality of the group moving forward.
"We have a good pre season in store for these boys and will look to hit the ground running next season."
