The visitors opened up a 10-point lead in the first seven minutes thanks to a penalty and a try from Cashmore, which he duly converted.

Glasgow prop Kevin Tkachuk responded with a try after the interval and Colin Gregor knocked over a penalty.

But Shaun Connor slotted a neat drop-goal and added a late hat-trick of penalties to seal the victory.

The defeat is a big blow for Glasgow's hopes of claiming a Heineken Cup berth next season as they were never able to recover from a disastrous start.

Cashmore began a personal purple patch by slotting the kick after Fergus Thomson was penalised for smothering the ball.

The full-back then dived over near the left touchline after the visitors switched possession from a scrum on the opposite side, and converted his own try.

Hopes of a Glasgow comeback were dashed by a string of unforced errors and they could have been further behind but for Cashmore missing a straightforward penalty.

Gregor missed two long-distance penalties. His first dipped onto the crossbar while the next had enough distance but drifted wide.

However, the Warriors' luck changed on the restart when good lineout possession set up a ferocious drive towards the line and Tkachuk plunged over for the try - Gregor hit the woodwork for a second time when his conversion rebounded from an upright.

The Ospreys hit back with Connor's drop-goal, Gregor responded with a penalty in front of the posts, but Connor added three more penalties as Glasgow lost their discipline.
