LOI review:  Shamrock Rovers fell further behind pacesetters Sligo Rovers thanks to a painful derby defeat at the hands of Bohemians at Dalymount Park.

The defending Airtricity League Premier Division champions are now nine points behind Sligo after the 4-0 thumping and a 2-1 win for the leaders at Dundalk.

St Patrick's Athletic remain second, four behind Sligo, after a 1-0 win over Shelbourne at Richmond Park came courtesy of Greg Bolger's ninth minute goal.

Peter McMahon's opener for Bohs in the 11th minute sparked some crowd trouble at Dalymount, but after order was restored the homeside went in at the break with a deserved lead. McMahon then doubled his tally seven minutes after the restart following a mix-up in the Rovers defence.

Stephen O'Donnell then saw red for the visitors when he pulled back Dave Mulcahy in the 66th minute and Bohs took advantage late one with goals from Dinny Corcoran and Karl Moore.

Michael Rafter's header gave Dundalk the lead at Oriel Park after 36 minutes but Sligo drew level through Danny North six minutes later and the striker pounced when Peter Cherri fumbled Joseph Ndo's corner in the 52nd minute.

Derry City and Bray Wanderers both suffered 30 defeats at home.

At the Brandwell, two from Gavin Brennan and a splendid chip from Declan O'Brien ensured Drogheda moved clear of Shamrock Rovers in third, a point behind Pat's.

Tadhg Purcell, Shane Duggan and Vinny Sullivan helped Cork close the gap on fifth-placed Derry with a handsome victory at the Carlisle Grounds.
