Luke Molyneux also found the net with a penalty as Rovers shook off the demons of letting a three-goal advantage slip against Wigan at the weekend.

Demetri Mitchell struck the post from 10 yards for Orient after meeting Theo Archibald’s ball across the box but that was as good as it got for the visitors in a first half dominated by the hosts.

It took an excellent reaction save from Killian Cahill to keep out Jay McGrath’s close-range effort before Doncaster took a deserved lead on 34 minutes when captain Bailey swept home Hakeeb Adelakun’s low cross from eight yards.

And the advantage was doubled in first-half stoppage time when Molyneux fired in from the spot after Frankie Okoronkwo was hauled down by Kaelan Casey.

Doncaster were comfortable in the second period, aided by Bailey’s 13th goal of the season on 49 minutes when he pounced on a spill by Cahill to poke home from close range.

And they saw out the game with comfort to make it seven points from the last nine available.
