Anthony Horgan ran in two tries in the space of five minutes to give Munster brief hope of overhauling their fellow Heineken Cup quarter-finalists, but in the end it was the home side who not only hung on but stole a bonus point at the death.
Adrift by 17 points at the interval, many of the home fans in the 6,169 crowd felt the Munstermen were dead and buried, but with scrumhalf Eion Redden at the hub of a major, wind assisted revival after the break the visitors clawed their way back to within seven points fifteen minutes from time.
Munster struggled in the first half when they played into the strong wind. The also struggled to contain the direct running of centre Mathew Watkins.
The Wales international notched the first of the game’s seven tries after half an hour while Munster were reduced to fourteen men with number 8 Stephen Keogh in the sin-bin.
The home side scored 10 points with Keogh off the field and were 20-3 to the good at half-time thanks to a second try from former Wales wing Richard Rees.
But the visitors were a different proposition after the break with the wind at their backs, some more steel up front and scrum half Eion Redden in lively mood.
Redden sparked a major revival with a brilliant chip and chase try six minutes after the break and Henderson’s conversion cut the gap to 10 points.
The Scarlets hit back with a close range try from Gareth Williams before Horgan’s quick fire double act threatened to turn the game on its head as Munster fought back to within seven points.
