Old Belvedere 21 Terenure College 15
Tries from winger David Mongan and back rower Steve Rockett helped Old Belvedere chalk up their first win of the Division One campaign.
'Belvo edged this Anglesea Road tie with out-half Andy Dunne in influential form - the Connacht man kicked 11 points, including two crucial second-half penalties.
The hosts led 15-12 at the break with 'Nure mustering tries from winger John Bollard and centre Killian Coleman.
But with try-scoring chances drying up, Dunne's boot saw 'Belvo to their first win in five league games.
