Hopp qualified for the 2013 PDC World Darts Championship by winning the Central European Qualifier in Bielefeld and in doing so became the second-youngest player ever to compete at the championships after Mitchell Clegg. Hopp played Charl Pietersen of South Africa in the preliminary round winning by 4 legs to 1 to set up a first round match against Denis Ovens. Hopp took the first and third sets to lead the match 2–1, but then lost six legs in a row to bow out of the tournament with a 2–3 defeat.
