Young Munster: Pens: Matthew Costelloe 3
With both sides riding high in AIB League Division 1B, there was little to choose between them in an even enough opening half.
Young Munster's Matthew Costelloe kicked penalty goals after 9, 20 and 28 minutes, but Ballymena bounced back to take a 10-9 half-time lead with Roger McBurney's 23rd-minute try converted by scrum half David O'Hara.
Munsters had the better of things in open play but Mike Prendergast's men could not get past a discipline home defence, and O'Hara completed his 10-point kicking haul with a final penalty, ten minutes from time.
It was an important win for John Andrews' charges, coming off the back of last weekend's league loss to Old Belvedere.
Ballymena will entertain 'Belvo in an AIB Cup quarter-final clash on November 21, while next Saturday will see them return to Division 1B fare with a trip to Munsters' Tom Clifford Park.
