In his second season leading behind the bench, the team were champions of the 2017–18 Euro Hockey Tour, winning both the 2017 Karjala Tournament and 2018 Sweden Hockey Games and placing third at the 2017 Channel One Cup and a respectable second at the 2018 Carlson Hockey Games. At the men's ice hockey tournament of the 2018 Winter Olympics, a loss to Canada in the quarterfinals prevented the Finns from progressing to fourth position or higher, ultimately placing sixth. The 2018 IIHF World Championship was Marjamäki’s last major tournament with the national team. Finland finished at the top of Group B, a group which included perennial heavyweights Canada and the United States, as well as recent silver-medal winners Germany. Despite early success, the Finns were again stymied in the quarterfinals, this time losing to Switzerland.
