While Glasgow seem to be able to do nothing else other than win at the minute, it was a different story at the start of the 2011/2012 RaboDirect PRO12 season.
With two losses from their opening two games against Ulster and reigning champions Munster, Warriors were hardly relishing a trip to the RDS - a ground where Leinster had won 28 regular-season games in a row.
Leinster meanwhile had recovered from their opening day 27-3 loss at the Ospreys with a comfortable 31-10 win at home to Newport Gwent Dragons.
And they led 13-10 against the visiting Warriors at half-time, Ian Madigan with the try as well as eight points from the boot of full-back Isa Nacewa.
The Irish side had enjoyed the majority of the possession but could only manage a three-point lead with Nick Campbell touching down and Scott Wight adding a penalty and conversion for Glasgow.

The early action of the second half saw Nacewa and Duncan Weir twice trade penalties, resulting in Leinster holding the 19-16 advantage.
But despite appearing in control, Leinster's clinical touch again let them down, with Warriors pouncing with ruthless effect.
Peter Horne seized on the ball before skating through the home defence on 66 minutes and with Weir adding the extras, the visitors suddenly sensed a famous victory.
Leinster pushed for a late comeback but Glasgow Warriors held on for a win that the Scots will be looking to repeat on May 31 at the same venue for their first ever RaboDirect PRO12 title.
