Billy Sharp scored his fourth goal of the season as Doncaster beat Gillingham 1-0 in the battle of the early League Two pacesetters.
The Gills arrived at the Eco-Power Stadium top of the table but were largely second best against their confident hosts.
Jordan Gibson twice went close for Doncaster in the early stages, with Jamie Sterry bravely blocking a fierce Jack Nolan strike in a rare opportunity for Gillingham.
Rovers took the lead after 30 minutes when Sharp hooked in from close range from a Gibson knockdown.
Luke Molyneux sent an attempted lob on to the roof of the net, while Sharp flashed a header narrowly wide as the hosts continued to push before the break.
Gillingham were stronger after half-time, but Doncaster continued to enjoy the better of the attacking.
Molyneux saw a shot deflected just over the bar and struck the woodwork with a searching cross moments later.
The Gills push hard for the equaliser in the later stages but struggled for clear-cut opportunities.
