A Piers Francis penalty gave Edinburgh an early lead and the Scots were only 6-3 behind at the break. But Keatley's right boot pushed Munster out of sight in the Cork rain.

Munster had to endure a difficult first quarter during which BJ Botha was signalled out for not scrummaging straight - referee Ian Davies sin-binned the South African prop in the 13th minute.

Francis, who missed a difficult first penalty, made no mistake with his second attempt as Edinburgh edged ahead on the scoreboard.

Davies' officiating of the scrum continued to dominate proceedings with Munster winning the next two penalties in the set piece, the first allowing Keatley to kick the hosts level.

Botha got the verdict over John Yapp on his return and Keatley converted the second of two quick-fire penalties, punishing Richie Rees for being caught offside.

Greig Tonks, Netani Talei and Ben Atiga tested the Munster defence late on, but Stander and company ensured the first half remained try-less.

Munster opened the second half on the front foot, JJ Hanrahan dinking a clever kick in behind Dougie Fife but the Edinburgh winger beat Johne Murphy to the bobbling ball.

Munster maintained their presence in the visitors' 22 and another Keatley penalty gave them a six-point buffer after Willem Nel infringed in a scrum.

The showery conditions made for a scrappy encounter and each penalty kick was becoming increasingly important.

Munster's stand-in captain James Coughlan was caught by a high tackle from Rees and Keatley slotted the resulting kick from a central position.

The province's direct style forced further mistakes from territory-starved Edinburgh and a fifth successful strike from Keatley had his side 15-3 ahead by the hour mark.

A sixth followed from the out-half before a pinpoint Hanrahan pass sent Ivan Dineen scurrying up the right touchline. He kicked ahead for the supporting Stander who went over unopposed for a 68th minute converted try.

Munster, who did the double on Edinburgh in the Heineken Cup pool stages, crossed again with five minutes remaining - replacement hooker Sherry scrambled past Talei with Stander providing the assist.
