Cardiff Blues were denied what would have been their second Guinness PRO12 win of the season by a late try as Munster claimed a 28-24 win at Cardiff Arms Park.
Flanker Paddy Butler went over for the score which broke Cardiff hearts in the 78th minute after the home side seemed to have clinched a narrow win with prop Adam Jones putting in a commanding performance including a drop goal attempt.
Munster opened the scoring when they earned a penalty for a ruck offence which was slotted from 35 yards by outside half JJ Hanrahan.
A penalty for full-back Rhys Patchell levelled matters before Hanrahan landed a 45-yard effort to restore the lead for the visitors. The exchange of penalties continued as a couple more ruck offences made it 15-9 to Munster with Hanrahan and Patchell trading kicks.
Just before half-time the Blues finally broke the kicking deadlock as Lucas Amorosino raced to the corner for a try on his debut.
Patchell missed the touchline conversion but Hanrahan maintained his perfect record with a sixth penalty to give Munster an 18-14 lead at the break.
Midway through the second half Vosawai burst off the base of a five yard scrum with the power to scramble over the line for a try converted by Gareth Davies as the Blues took the lead for the first time.
Hanrahan equalised, but with a penalty already awarded, Jones went for an ambitious drop goal which fell just a few feet short. It got the biggest cheer of the night, though Davies did add the three points from the resulting penalty kick.
