Plays his first Open since the 2011 Championship at Royal St George's, which he qualified for as the European Amateur Champion.
This time makes it after a spectacular climb up the European Tour rankings from 57th in 2017 to 13th last season.
Twice Danish champion before he turned professional, he also represented his country in the 2008 and 2010 Eisenhower Trophy World Championships, finishing runners-up to France on the second occasion.
Graduated to the Challenge Tour after winning the 2012 Nordic League, then came through the main circuit’s Qualifying School at the third attempt in 2013. His first success was alongside compatriot Thorbjorn Olesen at the inaugural GolfSixes event in 2017 and later the same year he produced a closing 65 to beat Marc Warren by four in the Portugal Masters.
Last season tied for third in the BMW PGA Championship, lost a play-off to Matthew Fitzpatrick at the Omega European Masters (after a last-day 63) and then two tournaments later captured the Alfred Dunhill Links Championship in Scotland by one from Tommy Fleetwood and Tyrrell Hatton.
A month after that he made it into the world’s top 50 for the first time, having been outside the leading 200 entering May 2018.
