Ollie Mehew grabbed a brace either side of a Sam Joel strike on a comfortable afternoon for the Under-18s.
David Lowe's side started the match brightly and took the lead after only 15 minutes.
Good build-up play from Rovers saw Mehew receive the ball in the area and he finished well.
Just past the half hour Rovers' lead was doubled as Joel continued his fine pre-season form by starting and finishing a move to put the visitors firmly in command.
On the stroke of half-time Rovers made it three with a goal on the counter attack. Central defender Matthew Platt sending Mehew clear on goal and he finished well for his second of the match.
The Under-18s never quite hit the same heights in the second half, but they'll have been satisfied with their final friendly match ahead of next weekend's league opener against Manchester City.
"In the first half we played some really good football," said coach David Lowe. "Although our play in the second was a little sloppy as we tired.
"Overall we controlled the game and looked comfortable. We played with a disciplined team shape with good attacking play."
