Besides darts, Waddell commentated on numerous other sporting events produced by Sky Sports and/or Matchroom Sport over the years. He regularly commentated on the four annual nine-ball pool events on which the two companies collaborated (World Pool Championship; World Pool Masters; World Pool League; and Mosconi Cup), particularly between the years of 1999–2003. However, as these events began to be hosted further away from the UK, Waddell gradually withdrew from the sport. He is remembered for coining the term "Golden Break", meaning when the 9-ball is pocketed directly from the break, giving the breaking player an immediate win.
