Biggar scuttles Leinster

Ospreys 25 Leinster 19

There had been little time for Leinster to recuperate after their Heineken Cup quarter-final loss at Toulon, and they came up just short against a home side who knew defeat would have effectively ended their own post-season aspirations.

Leinster remain top of the RaboDirectPro12 table despite defeat, and the bonus-point secured here may yet prove crucial in the battle withUlster and Munster for home semi-final advantage.
