Played in the 2018 Open at Carnoustie as European Amateur champion, winning a title many thought could go to his twin brother Rasmus, who was higher-placed on the amateur world rankings – 31st to 35th.
Two weeks earlier Rasmus had fired a closing 64 to leave his brother four strokes behind in second place at the Toyota Junior World Cup in Japan, where they were not surprisingly team champions.
The former European boy champions shared victory again later that year at the Eisenhower Trophy World Team Championship in Ireland, pipping by one stroke an American line-up which included current Champion Golfer Collin Morikawa.
That was Denmark’s first triumph in the event and now the brothers share more history as the first to win back-to-back DP World Tour events. Rasmus struck first at the Omega European Masters, then Nicolai lifted the Italian Open in September.
Both have since made it into the world’s top 100, and Nicolai, joint runner-up behind Thomas Pieters at November’s Portugal Masters and then tied fourth behind Morikawa at the DP World Tour Championship two weeks later, registered his second Tour title at January’s Ras Al Khaimah Championship back in the United Arab Emirates.
