Dave Chisnall hit his second nine-darter on the PDC-circuit this year in the 21st Players Championship of 2017 in Barnsley, after hitting a perfect leg earlier in May.
The St. Helens Ace hit the perfect leg in his match against Ryan Searle. The feat helped him on his way to a 6-4 victory in the first round of the Pro Tour event.
