In the mixed event featuring the top boys and girls from each country, Schmidt was the only boy to emerge from the two days with a 100 per cent record.
England won the inaugural competition 15.5-8.5 with Schmidt teaming up with Boys’ Amateur champion Conor Gough (Stoke Park) to win both their foursomes (6&5) and fourball (4&2) matches.
Schmidt, who in August became the youngest holder of the Lee Westwood Trophy, added a one-hole singles victory.
His fantastic season has been rewarded with a place in England Golf’s boys’ squad for next year.
His other 2018 successes have included becoming Yorkshire Boys’ champion, England Golf’s Champion of Champions at boys level, and being a member of both Yorkshire senior and boys teams who achieved national success.
