As World Champion, Higgins reached the quarter-final stages in only the Welsh and China Open tournaments. He helped to establish, and actively promoted, the World Series of Snooker – a tour intended to bring snooker to new venues outside the traditional United Kingdom and recently developed Far East markets. He won the inaugural event in St. Helier in June 2008, beating Mark Selby 6–3 in the final. Higgins also devised a new players' union with his manager Pat Mooney, called The Snooker Players Association. He won the Grand Prix for the fourth time in 2008, beating Ryan Day 9–7 in the final in Glasgow – his first ranking tournament win on home soil.
