A penalty from Tom Jordan was all Glasgow had to show for their efforts until the closing minutes of the second half

Late tries from Oli Kebble and Tom Gordon gave the scoreboad a more respectable look but by that point Glasgow's poor discipline and inaccuracies had helped put Ospreys out of sight.

The opening half was a tight affair with both teams battling for territory. Ospreys thought they had gone ahead through Keelan Giles from a breakout after Glasgow pressure but the score was chalked off due to a knock-on from Rhys Webb.

Giles eventually went over in the corner six minutes later with a fine finish to put the home side ahead.

A fine length of the field try from Sam Johnson was disallowed after Scott Cumming was adjudged to have knocked on when he won the turnover which started the move.

Gareth Anscombe stretched Ospreys' lead with a penalty but Tom Jordan replied with one of his own as Glasgow finally got points on the board just before the break.

In the second period, Ospreys extended their lead with a try from Keelan who won the race for the line after Jordan lost possession and Webb kicked downfield. Jack Walsh, on for Anscombe, converted then added a penalty to put Ospreys 20-3 ahead as the game entered its final quarter.

Glasgow had plenty of possession, kicking to the corner and trying to utilise their rolling maul, but substitute hooker George Turner was denied on three occasions while Ospreys were down 14 men following Dan Lydiate's yellow card.

Glasgow's failure to capitalise was punished when Mike Collins' kick and collect left the vistor's flat-footed. The centre passed to Walsh who looped the ball out to George North to finish. Reuben Morgan Williams, the substitute scrum-half, then secured the bonus-point try, going over from a scrum five.

The Warriors produced a late rally to score two tries from close range through Kebble and Gordon - both converted by Domingo Miotti - but it was all too late.

Glasgow will wait on news of Jack Dempsey who went off with a rib cartilage injury early on.

Franco Smith, Glasgow Head Coach

"We had execution errors where last week we dominated the scoreboard. The fact that in the last three or four minutes we created the same amount of space, the ball was going through the hands, shows there were individual errors which must be fixed."
