Leyton Orient assistant manager Kevin Nugent admitted the 4-1 scoreline was not a fair reflection of what was a tricky game for his side.
Harry Kane came off the bench to score twice and seal victory for the Os after Jimmy Smith`s header and an Andrew Whing screamer had put them in control. Rovers had pulled one back through Ben Chorley`s own goal.
Nugent said: "This was a fantastic result for us in what was a really, really, tough game.
"We gave the ball away a little bit too easily at times and it was only in the latter part that we put the game to bed. But overall, it was a good display and a good victory. You look at the result and it looks a straightforward win but there's no such thing as an easy game in this league and it was a real scrap.
"I think we made the substitutes at the right time and Harry Kane came on and scored a couple of goals. He took his chances well and linked up well and he's a real talent who is still learning the game.
"He was possibly going to start the match but we always speak about the strength of the whole squad and the lads that came on proved it."
