Derry City 0 Bohemians 3
Bohs stretched their lead at the top of the table to 11 points with a comfortable win at the Brandywell.

Bohs extended their lead a minute before half-time when Bobby Ryan connected with a poor defensive header to beat Alan Gough with a stunning volley.
The game was over as a contest two minutes after the break when Derek Coughlan headed home Mark Rutherford's corner for the third.
