The Ospreys are still winless away from home in this season's Celtic League, with Shane Williams' last-second drop goal attempt agonisingly shaving the left upright and going wide.

Munster's second string survived 10 minutes of injury-time as Paul Warwick's hat-trick of penalty goals set the province up nicely for next weekend's European Cup assault.

A swirling wind proved difficult to judge, particularly for Ospreys fly-half James Hook, who missed three of his four penalty attempts in the opening half.
