2009 Six Nations where he played his 16th and last International match, against
France at the
Stadio Flaminio in
Rome. Marcato went on playing club rugby for Benetton Treviso until 2010, then returned to Petrarca; in early 2011 he was loaned back to Benetton as replacement in Celtic League; at the end of the 2010–11 season he came back to the Italian championship and signed with
Calvisano which had just been promoted to the Eccellenza (the first tier championship).
