Munster recovered a 21-8 first half deficit to edge out battling Borders in Friday's Celtic League encounter at Musgrave Park.
Munster (8) 29
Tries: Henderson, Horgan 2, Blaney
Cons: Holland 3
Borders (21) 21
Tries: MacLeod, Kane 2
Cons: Morton 3
Two second half tries from left-wing Anthony Horgan proved crucial for Alan Gaffney's side.
Borders, second from bottom in the table, ran in three first half tries including two touchdowns from openside flanker Daniel Kane.
But Munster, despite being minus eight regulars, fought back after half-time.
A third-minute kick from scrum-half Eoin Reddan saw Borders concede an early
penalty for full-back Jeremy Staunton from 45 metres.
Staunton met opposite number Scott Paterson in a try-saving tackle 10 minutes
later, before Shannon hooker James Blaney touched down by the right touchline.
A lapse in the home side's concentration saw Kane lurch over for his first score six minutes later with centre Gareth Morton converting.
Morton then added the extras again to second row Scott MacLeod's effort following a timely offload
by fly-half Tanner Vili.
Rob Henderson scored a late Munster try
A shock win looked on the cards when Kane got in under the Munster posts in
the 32nd minute, Morton hitting his third success for the 13-point lead.
But Munster clicked into gear in the second half, the addition of backs Mike
Mullins and Dominic Crotty seeing them attack Borders at will.
Horgan ran effortlessly under the posts 10 minutes after the break - with Holland converting - and he then slashed open the Borders rearguard on the hour
mark to score a great individual try.
Holland's conversion gave Alan Gaffney's men their one-point lead with 18
Munster survived a late scare when Vili's attempted drop goal was charged down by Holland.
And Munster centre Rob Henderson crossed in the seventh minute of stoppage for a converted try and an unlikely bonus-point win.
