In the second all-Guinness PRO14 encounter of the day, Munster were in formidable form as they matched Leinster by also claimed a bonus-point victory in their Champions Cup opener.

Jeremy Loughman’s try and two Tyler Bleyendaal penalties put the visitors ahead going into the break before Keith Earls and Andrew Conway added to Munster’s total after the restart.

Following two first-half penalties from the boot of Luke Price, Aled Davies crossed for Ospreys in the 79th minute for a consolation effort – converted by Price again to close the gap.

But Johann van Graan’s men were not done yet and with the clock in the red, James Cronin went over for Munster’s fourth try and the bonus-point to cap off a perfect evening.

Challenge Cup relief for Blues and Dragons

Cardiff Blues put their indifferent Guinness PRO14 form behind them as they began their latest assault on Europe with a comfortable 38-16 bonus-point triumph at Calvisano.

Matthew Morgan and Seb Davies both crossed in the first half for the two-time Challenge Cup winners to put them 17-10 ahead, with Simone Balocchi responding for the hosts.

A pair of Paolo Pescetto penalties edged Calvisano to within a point but further Blues tries from James Botham and Rey Lee-Lo put the game to bed before Harri Millard added a fifth.

In Wales, Dragons were inspired by a Taine Basham hat-trick as they secured their bonus-point before half-time against Castres before eventually prevailing 31-17.
