Although billed as a full international and watched by a crowd of around 40, 000, the match effectively turned into a glorified training session as Brazil substituted their entire starting line-up in thesecond half.
Another Jamie Robinson break just before half-time should have given Czekaj his second try of the night, only for Shane Williams - restored to the Ospreys starting line-up - to prevent his opponent grounding the ball.
Walsh, who was restored to thestarting line-up because of an injury to Willo McDonagh, then grabbed his second to put the Lurgan Blues well in control.
