The former Greystones fly-half kicked three penalties, a conversion and a drop goal as Ray Ward's men were rewarded with their first win of the season.

Two penalties from Murphy, who kicked six penalties and a drop in Carlow's last minute 23-21 loss to Buccaneers last week, and Russell Armstrong's converted try saw the midlanders to a 13-3 half-time lead.

Andy Tallon had notched Lansdowne's sole score, and the Dubliners were to offer little in the second half bar Fiachra Baynes' 20-metre sprint over try.

Loosehead prop Padraig Brennan muscled over for their second try to confirm Carlow's first AIL success since the middle of March.
