Mark Byrne and Olly Lee both scored inside the first 15 minutes as Gillingham booked their place in the FA Cup third round with a 3-0 victory over Doncaster.
Byrne opening the scoring in style after 11 minutes with his first goal of the season, firing past Seny Dieng after controlling the ball brilliantly with his chest.
The Gills’ second was even better as Lee latched on to Tom O’Connor’s lofted pass and lobbed a hapless Dieng from 19 yards.
O’Connor somehow squandered a golden chance to put Steve Evans’ side 3-0 up within 25 minutes when he shot wide from Brandon Hanlan’s clever cutback.
Rovers, who sit two places above the Gills in League One, never looked like matching the feat of reaching the fifth round last season.
Rakish Bingham headed wide with their best chance of the opening half, while James Coppinger shot straight at Gills goalkeeper Jack Bonham eight minutes after half-time.
Hanlan sealed Gillingham’s victory with a brilliant solo effort after 68 minutes.
