Dekker made it for the third time in a row to the second round of the World Championship, after winning over Ryan Joyce and losing to Jonny Clayton.

It was his only major in 2020 season and because Dekker was not able to qualify for another World Championship, he dropped out of top 64 of PDC Order of Merit, losing his Tour card after 4 years.

He was automatically qualified for the Final stage, but gaining just two points in the Q-school Order of Merit, he finished 44th in the rankings and did not get a new Tour card.
