Munster bludgeoned their way to a fiery 19-12 win over Edinburgh in the Magners League on Friday, helped by a try from Marcus Horan.
Munster's best-laid plans were torn up at when they lost Donnacha Ryan, Paul Warwick and Niall Ronan to injury - all around the quarter-hour mark.
But, despite five missed place-kicks, Warwick's replacement, academy player Scott Deasy, stamped his mark on the game with a decisive 58th-minute try and Edinburgh just could not strike back.
The Scottish side had moved 12-8 clear early in the second half thanks to David Blair's third penalty success, however Munster, fresh from a training camp in Lanzarote, hit back to extend their unbeaten home run to 15 matches.
The 21-year-old Deasy was making only his second league appearance and was introduced just as Edinburgh seized the early initiative, with outside-half Blair sending busy hooker Andrew Kelly through a gap.
Rob Moffat's men looked the more threatening in open play, the injuries and a malfunctioning lineout did little for Munster's confidence and a Blair drop-goal deservedly sent Edinburgh in front.
The hosts responded quickly and Ian Dowling was held up just metres out before fit-again prop Marcus Horan burrowed over from close range, crowning his first provincial start since October with a try.
Deasy pulled his conversion attempt across the posts and Edinburgh, eager for work and protecting the ball well, set up Blair's first successful penalty on 25 minutes.
Deasy crashed a penalty of his own off the post, three minutes later, but he did punish an Edinburgh scrum infringement to move Munster two points clear.
Edinburgh nipped back ahead for half-time though, as a superb line break by Nick De Luca saw them rampage up close to the Munster line, Alan Quinlan was ruled offside and Blair booted his side into a 9-8 lead.
Deasy had the distance but not the accuracy from a long-range penalty just after the break, and an absorbing tie swung back in Edinburgh's favour when flanker Quinlan was sin-binned for a ruck offence and Blair converted the penalty.
Deasy missed an immediate chance to reply but held his nerve to fire over a 57th-minute penalty.
Off the restart, Munster snaffled back possession before Deasy broke the Edinburgh line, dangled a chip kick towards the line and took advantage of a favourable bounce to grab a priceless try.
Deasy failed to convert and Munster had to show some defensive steel to keep Edinburgh at bay in the closing stages.
Mark Robertson was thwarted by Mike Sherry with the line in his sight, Lifeimi Mafi saw yellow for taking out support runner De Luca as the visitors probed out wide once again and there were two vital turnovers close to their line as Tony McGahan's charges defiantly held on.
