Ian Keatley's late drop-goal earned Munster a dramatic 16-15 win over Glasgow Warriors at the Scotstoun Stadium and ensured they held onto their place at the Pro12 summit.
Fly-half Keatley split the posts with four minutes remaining, ensuring his penalty miss in the first half did not prove too costly.
The 29-year-old opened the scoring with a routine three-pointer before converting Andrew Conway's 11th-minute try, but Glasgow, boosted by the return of eight Scotland internationals, fought back and took the lead through scores from Ali Price and Nick Grigg.
It was Keatley who had the final say, though, ensuring Munster were not deposed by Ospreys, who defeated Edinburgh 31-22 in Friday's other fixture to go second.
After falling behind that was a huge effort to get back up & secure the win on the road. #GLAvMUN-- Munster Rugby (@Munsterrugby) December 2, 2016
Keelan Giles touched down his fourth Pro12 try in as many matches in a bonus-point victory, adding to first-half efforts from Dafydd Howell, Nicky Evans and Ma'afu Fia.
Ospreys were unable to add to their tally despite Grant Gilchrist and Allan Dell seeing yellow in the second half, with Bill Mata's try not enough to end Edinburgh's search for a first away win in the competition this season.
Leinster could displace the Welsh province with victory over Newport Gwent Dragons on Saturday, while a bonus point would take them level with Munster at the top.
