Winter 1999-2000:In the first Aberdeen 9-ball league, held at Barracudas, Neil Tocher emerged top of the round robin system to pip George Brandy for the title. Such was the popularity of this new sport, a second league-style event was held in spring 2000 at the same venue, and Boyd Strachan claimed the honours, with youngster David Marcella claiming the runner-up spot. By summer 2000, more and more players were playing 9-ball in Aberdeen, and snooker player Jim O'Hare won 19 of his 20 league matches to win the title from 8-ball pool player John Falconer.

  By now, a seasonal 9-ball championship was the norm, but the growing interest meant a switch to a larger venue; Rileys Chapel Street hosted the Autumn 2000 version, and Willie Guyan held on in a nervy finish to deny O'Hare a second title by the margin of just 1 rack; both players had won 22 of their 25 matches, but Willie got the verdict on rack difference.

  The 5th league championship, again at Rileys, was held in winter 2000-01 in a "champions league" style format. In the final group of 6 players, Graham Reid was favourite after an unbeaten qualifying campaign, plus victories over his first 3 opponents in the final group. However, Jim O'Hare beat both Reid and Brian Rennie to stake a claim, and Reid, needing only a win over Willie Guyan in his final tie, lost 9-7 to hand the title to O'Hare, with Guyan runner-up.

   In spring 2001, Guyan and O'Hare occupied the top 2 spots at the halfway stage of the new "points per event" style league at Rileys; points would be allocated to competitors in each of 10 counting events, with the leader at the 10 week stage declared the winner in the first league held under the ANBA banner; all this time, an Aberdeen snooker legend had been cutting his teeth on the 9-ball tables-Derek Hearns was outside the top 10 at week 5 before finding his feet emphatically-winning the last 5 events to deny Guyan the title.

   Aberdeens top snooker player was by now a top 9-ball player, and hit record setting form in the summer 2001 league. Derek Hearns won 7 consecutive counting events to win a second consecutive title; fellow snooker player Stuart Johnson was runner-up in many of the finals, and in the overall championship.

   It was no surprise when, in autumn 2001, more snooker players converted to 9-ball, and John McCann and Mark Oaten joined the fray. However, Dereks Hearns' experience carried him over the winning line-a run to the semi-finals in week 10 confirmed the title, as McCann finished a creditable second.

   A controversial development came about in winter 2001-02, when the ANBA league, again at Rileys, was split into 3 divisions. The upshot was that Hearns chose not to defend the title, and John McCann romped to victory in the 10-man top flight. Neil Tocher, original ANBA champion, won the first division, and Gary Aitkenhead the second.

   The format stayed for spring 2002 in the final league to be held at Rileys, albeit with just 2 divisions. It was the same result, however as John McCann and Mark Oaten traded wins throughout the season, with the former emerging as the overall victor. Joni Holden won the first division.
