Trio secure Grand Slam of Darts qualification after World Cup of Darts final run
Henderson, together with compatriot Peter Wright, managed to win the World Cup of Darts at the expense of the Austrian duo Suljovic and Rodriguez.
The finalists of all major TV tournaments receive an invitation to participate in the Grand Slam of Darts. Wright, however, had previously qualified by taking the title at the World Matchplay.
For Henderson it will be his first participation in the Grand Slam of Darts since 2010. Then he made his debut. Suljovic previously competed in 2016, 2017 and 2018, while Rodriguez made his appearance in 2014 and 2015.
