Munster weather late storm
Reigning champions Munster look well set for the knockout stages after defeating a spirited Aberavon side.
Captain Sean Dougall, part of a superb back-row, was content to have negotiated a potential minefield and preserve their four-point lead at the top of the table.
"It was a dogfight but we dug in and took our chances when it mattered, but we were not ruthless enough," he said.
"Playing in Wales is never easy. We expected a tough crowd and got one."
In the first half, a slick backline move cut open the hosts to allow Ronan O'Mahony to canter over. JJ Hanrahan added the extras and a penalty to send Munster into the break 10-3 up.
Munster started the second half at a frenetic pace. Danny Barnes seared over, and Hanrahan added a penalty.
Aberavon, aided by a dubious CJ Stander yellow card, fought back with a try and two penalties, but Munster weathered a late storm.
