Qualified off the world rankings for his Open debut in 2019 and called his week at Royal Portrush the most fun he has ever had at a golf tournament, even though he missed the halfway cut.
Dahmen guaranteed himself an instant return by finishing joint fifth in the 2020 Arnold Palmer Invitational. Three Open Qualifying Series spots were up for grabs, but the top four of Tyrrell Hatton, Marc Leishman, Sungjae Im and Bryson DeChambeau were already exempt.
He just missed out on the 2018 championship when he was joint runner-up in the PGA Tour’s John Deere Classic, which annually offers the final exemption, and in 2019 he was solo second behind Max Homa in the Wells Fargo Championship.
Dahmen, who has suffered testicular cancer, turned professional in 2010 and was a member of the PGA Tour Canada until 2014 when he won twice and topped the Order of Merit to graduate to the Web.com circuit.
That led to further promotion to the PGA Tour by less than $1,000 when he finished 25th on their money list and he went on to make his first two major appearances in the 2019 PGA Championship and U.S. Open. In March he claimed his maiden PGA Tour title, winning the Corales Puntacana Resort & Club Championship.
