It means that with only two weekends to go there are only two points splitting the top three teams – with the Scarlets and Celtic Cup winners Ulster on course for a potential title shoot-out on the last weekend.
While Ulster picked up an away win at the Borders on Friday night, they failed to earn a bonus point. That gave the Scarlets the chance to return to the top of the table, but they had to work very hard to overcome a thoroughly committed Glasgow side.
The Scottish team headed to Wrexham knowing they needed something out of the game to give themselves a chance of the Borders to the second Heineken Cup spo for the Scots. In the end, they picked up two tries in each half to gain in invaluable bonus point.
Wales scrum half Dwayne Peel ran in two crucial second half scores to earn the man of the match accolade. Pack members Chris Wyatt and David Hodges got the other tries.
Stephen Jones weighed in with 13-points while Gareth Bowen completed the scoring with a penalty after replacing the Wales fly-half.
