Stephen Kenny got exactly what he would have wanted from his 100th game in charge of Dundalk, a victory that maintains the champions' flawless start to the season.
Five games played, five wins recorded, 11 goals scored and none conceded. As far as title defences go, it has been some start. For good measure, the victory means that Kenny's side have now gone 21 league games without defeat at Oriel Park, equalling the club's top-flight record for such a feat.
His side did irreparable damage to their opponents with a powerful first-half display. The opener arrived after 17 minutes, the result of devastating simplicity. Daryl Horgan cut the Sligo back four wide open with a glorious pass and the finish from David McMillan was even better, his side foot finding the top left-hand corner of Ryan Coulter's goal.
The second arrived nine minutes later. Dane Massey's cross was cleared by Stephen Folan but the ball fell to Richie Towell and he fired his 18-yard drive past Coulter.
McMillan was denied a second by two wonderful Coulter saves in quick succession, initially after a quick turn and shot. From the subsequent short corner, the striker's glancing header was somehow clawed away by the goalkeeper.
The Bit O'Red needed a response and Morten Nielsen was denied by former Rovers goalkeeper, Gary Rogers, in the 39th minute before David Cawley's left-footed effort curled just over the top.
The second half saw Dundalk in firm control and Towell grabbed his second in the latter stages, tapping home from Ronan Finn's pass before Rogers made a fine save from Nielsen, securing Dundalk their third 3-0 win in the space of seven days.
