The sides were level 14-14 in injury time when the home side were awarded a penalty. Fully expecting Shane Geraghty to kick his points Munster turned their backs but the out-half took a quick tap to catch them napping and earn a seven point cushion.
Geraghty and Ronan O'Gara had each kicked two penalties and both had failed to convert the tries of Chris Ashton and David Wallace. Munster's other points came from a stunning Paul Warwick penalty from 45 metres that opened the scoring for his side in the 16th minute.
