Cardiff Blues ground out a 10-7 victory over Zebre in a tough Guinness PRO14 encounter.
A converted try from Owen Lane and a penalty from Jarrod Evans saw Cardiff earn a third consecutive victory in the competition.
The points for both sides were all scored before half-time, with Evans’ 39th-minute kick proving decisive.
Cardiff racked up a 37-8 home win over the same opponents in early November but it was a different story in Parma, with points at a premium.
Lane broke the early deadlock with a 27th-minute try, taking on a pass from Rey Lee-Lo and darting through to touch down beneath the posts, allowing Evans a straightforward conversion.
Zebre had failed to take their chances until then but they soon levelled up, shortly after Aled Summerhill had a Cardiff try disallowed for failing to ground the ball to the television match official’s satisfaction.
Giovanbattista Venditti intercepted a Blues pass and charged from his own half to the try line, with Guglielmo Palazzani adding the conversion.
Evans booted what proved to be the match-winning penalty to take Cardiff into the break with a slender lead.
Zebre saw plenty of the ball in the second half, creating openings but failing to find a clinical finish, allowing Cardiff to complete a league double over their hosts.
