Glasgow Warriors 12-6 Leinster
Leinster passed up the chance to return to the top of the Guinness Pro12 table, but did manage to close the gap on leaders Connacht with a losing bonus point in their 12-6 defeat to Glasgow Warriors.
The Blues were guilty of errors throughout and displayed effort but little inspiration with the occasional line break coming to nothing.
Glasgow's stand off Rory Clegg, newly returned from a spell in France with Oyonnax, was their hero kicking two penalties in each half. Isa Nacewa kept Leinster in touch with his two first-half penalties.
Glasgow kicked off on an improved Scotstoun surface after the mid-winter postponements, but it was the visitors who took the lead with a penalty in just the third minute from Nacewa.
In the 14th minute a penalty from Glasgow's Clegg, after a Leinster kick out on the full had given them position, brought equality.
Three minutes later Clegg eased Glasgow ahead with his second penalty success.
The half consisted of long periods where each side in turn had prolonged periods of possession with little ground gained.
However a bright kick and take on the left wing by Leinster's Dave Kearney should have brought a try when an overlap was created on the right. However stand-off Cathal Marsh passed behind his troops and into touch.
Leinster soon did equalise with a penalty from Nacewa, but the winger went from hero to zero as he closed the half by missing a straightforward penalty chance, so the teams went in with the score tied at 6-6.
Glasgow restarted with vigour, trapping Leinster in their 22, with Clegg easing them back into the lead with a 50th minute penalty which he extended seven minutes later with his fourth success.
The quality of play then again fell away with neither line under serious pressure as defences ruled.
Then, with five minutes left, a long penalty allowed Leinster to establish themselves in the home 22 and the chance to win the match. But they were repulsed until Peadar Timmins was penalised for side entry.
