Munster moved to the top of the Magners League table as they scored four tries in a 28-20 win over Cardiff Blues at Musgrave Park on Saturday night.
Niall Ronan scored an early try for Munster but a Richard Mustoe touchdown helped Blues to a 10-7 half-time lead.
Ma'ama Molitika scored another Blues touchdown but Paul O'Connell, Ronan and Justin Melck then scored Munster tries.
Ronan O'Gara converted all four of his side's tries while Ben Blair kicked two penalties and two conversions.
The hosts got off to the perfect start with a try by Ronan inside two minutes, capitalising on Rua Tipoki's clever kick, with O'Gara adding the conversion.
A Blair penalty put the visitors on the scoreboard before a Mustoe try and Blair conversion in the 33rd minute edged Cardiff ahead.
Five minutes after the break Molitika's converted try extended the advantage before O'Connell's touchdown, with an O'Gara conversion, reduced the deficit to 17-14 after 52 minutes.
Ronan then got his second try of the night midway through the second half and when Melck went over three minutes later, O'Gara's kick gave the Irish province an 11-point cushion.
Blair soon kicked his second penalty of the night but there was no way back and his missed effort seconds from the end denied his side a losing bonus point.
Munster secured a bonus point to go top of the table with three wins from three matches while the Blues lie sixth in the standings.
