Greebe qualified for the 2008 PDC World Darts Championship, losing in the first round 3-2 in sets to Peter Manley. Afterwards, Greebe began playing for the BDO/WDF again, reaching the quarter finals in the 2008 Isle of Man Open. But in August 2008, he once more played in the PDC Pro Tour, reaching the second round of the PDC German Players Championship, beating Erwin Extercatte before losing to Mark Dudbridge. After the match, Toon famously quoted to the press "I could smell Marks breath from my prep room - I can still smell it today, it was fierce. I believe it gave him the edge today".
