Manager Grant McCann said his team's ruthlessness in front of goal made the difference as Rovers earned the bragging rights over neighbours Scunthorpe United in Sky Bet League One.
Rovers took the lead through a Ben Whiteman effort after six minutes and had doubled their advantage by the 10-minute mark thanks to a calm finish from Herbie Kane. The match was wrapped up in the second half when John Marquis scored his 12th league goal of the season to make the final score 3-0.
