Glasgow's points came from tries by Aidan Cross and Duncan Munn with two successful conversions by Matthew Urwin.
Jack Mann started at No.8 and although the scoreline didn't got their way, he says Warriors have positives to take from the contest.
"I think we can be pretty pleased with our effort in general and certainly our attack came together pretty well, especially in that first half," Mann told Scotland Rugby News.
"I think in the second half things didn't quite come together as they had in the first, but defensively we did well to keep us within seven points for quite a while until the last two tries near the end.
"I thought that some of the younger boys in the team and who came off the bench really stood up well and can be pleased with their performances.
"Guys will have learnt a lot from that. Sometimes younger guys don't get enough game time, but with more A games coming up and the Premiership draft they will keep learning through games."
