Macdonald's next challenge is the World Championships, which start in Blackpool next Monday.
He said: "I started off playing for a pub team and then Igot selected to play forMerseyside and finished up top of the county rankings three years in a row.
"I wanted to play against better players so Ijoined the IPA Tour whichgoes around the UK. I'm in my third season on the tour and they have a two year ranking system. I'm provisionally ranked 24th in the country and I have enough points to turn pro.
"I was hoping to get in last season, but you need to get into the top 64 on the tour and I was only 67th. I was determined to make it this year and after a good start to the season I'vemanaged to keep it going, so I'll be joining the Pro Tour next January."
