Munster grind out win on way to the summit
Munster celebrated a hard-fought win over Glasgow by replacing the Scots at the top of the RaboDirect Pro12 table.
Duncan Weir's brace of penalties had the Warriors 6-3 ahead at the break.
But Munster back JJ Hanrahan pierced the home defence for the game's only try and his precision with his right boot put the Irishmen in charge.
Weir scored an early penalty to take his Pro12 points tally to 400.
The visitors were awarded a penalty of their own and Hanrahan smacked an almighty kick from the halfway line to level after 20 minutes.
Glasgow enjoyed some free-flowing rugby for a short while, with Byron McGuigan and Sean Lamont making impressive incursions into the Munster half before one of the visiting players used his hand to scoop the ball out of the middle of the scrum. Weir put Glasgow 6-3 ahead with a straightforward penalty.
The complexion of the game changed further when Tyrone Holmes gave away a penalty in front of the posts, far too inviting for Ireland Under-20s star Hanrahan to miss. Welsh referee Ian Davies showed a yellow card to James Cronin for foul play as tempers frayed and Glasgow chose to go with the scrum, which they had edged in the previous 50 minutes, rather than kick for three points from close range.
Josh Strauss had three attempts to cross the line and Swinson one, but the outnumbered Munster side defended manfully. Glasgow attacked but could not penetrate the Munster defence.
