Munster’s second-half comeback was not enough as provincial rivals Ulster edged them 15-14 to win at Thomond Park for the first time since May 2014.
Dan McFarland’s men did all their scoring in the first half, James Hume tagging a late score onto maul tries from Jordi Murphy and Tom Stewart for a 15-3 lead.
Munster had produced a disjointed performance up to that point, but they absorbed Malakai Fekitoa’s sin-binning and Jack Crowley took his tally to three penalties.
