"I just can't believe it, I have just beaten my idol," Harbour said emotionally afterwards in conversation with interviewer Helen Chamberlain. "I've followed Phil for years. I'm so pleased."
Harbour had also beaten Martin Adams earlier in the tournament. In the last four, however, he lost 5-2 to Richie Howson. The latter in turn went down 6-2 to Leonard Gates in the final of the World Seniors Darts Masters.
