Cork City produced a super defensive display to secure a hard fought win at Derry City.
For Peter Hutton he will feel for the second match in a row his side did more than enough to get at least a share of the spoils. But it was John O'Flynn's first half goal was enough to separate the sides.
Cork got off to the perfect start as they took the lead on 13 minutes when Josh O'Shea's left wing cross found an unmarked John O'Flynn, who fired high into the net. Derry had numerous chances to equalise but Cork held firm to keep up the pressure on leaders Dundalk.
Eamon Zayed came back to haunt former side Bray as John Coleman claimed his first away win as Sligo manager. In only his second game for the Bit O'Red after his loan move from Shamrock Rovers, the Libyan international broke the deadlock in the 47th minute at the Carlisle Grounds.
Adam Mitchell could not cut out Evan McMillan's header, with Zayed getting in behind to angle in a 15-yard half volley. Struggling Bray side should have levelled ten minutes later. David Cassidy lobbed the advancing Gray Rogers but the ball dropped agonisingly wide.
