The visitors ltook an earl lead with a penalty goal by Isa Nacewa after only two minutes of play but Glasgow responded with a series of attacks in their opponents’ 22m area that culminated in a penalty by outside half Rory Clegg, playing in his first match since returning to the Scottish side.
The kicking duel continued with a second successive penalty by Clegg, the Glasgow advantage neutralised by a second success for Nacewa to leave them level at the break.
On the turnover, The Warriors’ momentum ended with a penalty award and a third goal for Clegg giving Glasgow a 9-6 advantage.
Glasgow were rewarded with another penalty and again Clegg delivered the points.
Minutes later when Leinster won a penalty they opted to run the ball but Glasgow were given another reprieve when referee George Clancy judged that the visitors had not released after the tackle.
Leinster however were given a further chance from a penalty line-out, but once again the visitors’ attacking efforts were ruined by an untimely turnover.
But when Isaac Bosswas tackled high, Leinster were handed another lifeline with a penalty created line-out only for the visitors to transgress at the breakdown allowing Glasgow to kick long for touch leaving Leinster helplessly watchihg the clock tick down to full time and to defeat.
