Corey Flynn went over for Glasgow's first try

Ospreys forged into a 14-0 lead after tries by Keelan Giles and Josh Matavesi, but Corey Flynn got a depleted Glasgow side back in the game before half-time before they took the lead thanks to a Peter Murchie score.

But the hosts responded with scores from Tyler Ardron and Kieron Fonotia to earn the bonus point. The victory sees the Ospreys leapfrog Munster and go second, while Glasgow are 12 points adrift of fourth.

Glasgow head coach Gregor Townsend praised the effort shown from his players and feels there are positives his men can take from the loss.

Gregor told glasgowwarriors.org: "It's frustrating. I thought a huge amount of effort went in, especially in that second half.

"We got ahead through some really good play and lots of effort in carrying the ball. We played most of that second half in their half.

"I think they were only in our half twice and they came away with two scores so it is disappointing for the players who put in that huge effort and presented a lot of pressure.

"There was a number of positive aspects, it is just frustrating when you look back and there are parts of your game that are really good. Our set-piece and our scrum have been really solid during this period.

"Some individuals worked really hard, forcing turnovers, getting on the ball on a number of occasions. I thought Brian Alainu'uese carried the ball really well. The back-line functioned really well for the first time they've played together".

Warriors take on Newport Gwent Dragons next weekend with a win needed to maintain any realistic hope of a play-off spot.

Gregor said: "We've got to make sure that we regroup and we defend better than we did yesterday and that we are clinical in our finishing and that is what Ospreys did.

"If we want a chance a chance to make the play-offs we have to show that we have worked on over the last few weeks, as well as a real determination in front of our home crowd.

"This is our last week of players away and if we can end this series with a win it will give us a boost going into the Connacht game in a few weeks".

Yesterday's match was significant one for Pat McArthur, who picked up his 150th appearance in a Glasgow jersey. Gregor praised his service to the club over the years.

He said: "He has been a great club man. He is a very good player in his own right but behind the scenes he really helps us function well as a team.

"Even before yesterday's game I heard him in the changing room encouraging the players.

"He always puts the team first. 150 caps shows how consistent he has been over the last few years".
