Alfie May scored twice as Rovers’ Development side beat Grimsby Town 3-0 at Cantley Park.
The front-man opened the scoring after a quarter-of-an-hour, as he raced clear and fired beyond Ollie Battersby.
Will Longbottom doubled the lead after half-time with a back-post header, before May added a third just two minutes later to make it back-to-back wins in Central League North.
Rovers return to the Keepmoat Stadium to take on Peterborough United on Saturday February 9. Tickets are available from the Club Doncaster Box Office, on 01302 762576 or at tickets.clubdoncaster.co.uk
