Leinster have come out on top in tonight's Pro12 derby against Ulster.

It was a low-scoring affair at the RDS as the away side claimed a losing bonus point in an 8-3 result.

Jonathan Sexton kicked Leinster in front with an early penalty, before Paddy Jackson equalised.

However, Leinster went into the break 8-3 up as Sean Cronin scored the all-important try after a rolling maul.

Ben Te'o almost added another try but knocked on with the line at his mercy.
