Rovers came into the match on the back of two defeats, but were a class above Gillingham, who have now lost their first three matches.

Greenacre put Rovers in front midway through the first half when he headed home Chris Shuker's right-wing cross.

Gillingham striker David Graham blazed over the hosts' best chance, before Davies fired the second from 18 yards.
