Tramore were forced to settle for 12th place behind winners Parco di Roma G&CC as snow reduced to the European Men's Club Trophy from 54 to 18 holes.
The 23-team event was ravaged by heavy rain on Thursday and while the opening round was eventually completed on Friday with the Italian club heading Portugal's Vilamoura by virtue of their better discarded score, no play was possible on Saturday due to snowfall at Pravets Golf Club in Bulgaria.
The Parco di Roma team of Enrico Di Nitto (68), Renato Paratore (70) and Michele Cea (72) finished on 138 (-6) alongside Clube de Golfe de Vilamoura's Vitor Lopes (68), Joao Carlota (70) and Nathan Brader (75).
Under the rules, the Italians won by virtue of their better discarded score — Cea's 72 to Brader's 75.
Tramore posted a total of two over 148 with Robin Dawson (tied ninth in the individual after a 72 with Paul Flynn shooting 76 and Christopher Butler 77.
