Hopp is on course to only get into the worlds on an invite
From wiki:
The field will consist of 72 players, 16 players into the preliminary round and 56 players straight into the first round. There has been a change to the qualifying criteria from recent editions of the tournament. Previously, the top four non-qualified European players from the Pro Tour Order of Merit would gain places at the championships; now the four places go to invites at the PDC's discretion.
He'll have to cash for over £10k in the the two remaining pro tour events to get in on prize money by my maths. Only £22k cashes so far this year!
