Defending champion Selby suffers shock defeat at UK Championship

LONDON, Dec. 2 (Xinhua) -- Defending champion and world No. 1 Mark Selby suffered a second round exit at the UK Championship as he lost 6-3 to fellow Englishman Scott Donaldson.

Donaldson, ranked 66th in the world and the semifinalist of the Welsh Open last season, ended his 10-match losing streak by beating John Astley 6-2 in the first round at the York Barbican and this win over Selby sets up a last 32 clash with China's Li Hang.

Selby looked comfortable in the early stages as he went 2-0 up with a top break of 68, but Donaldson hit back to win three frames in a row with top runs of 88 and 51. World Champion Selby won the sixth for 3-3, but he didn't score a point in the last three frames as Donaldson fired breaks of 90, 77 and 84 to win in style.

Former champion Neil Robertson of Australia made three consecutive centuries for the second match in a row as he beat Ken Doherty 6-2. Australia's Robertson trailed 2-1 but then took five straight frames with high scores of 102, 124, 129.

Robertson is still in 17th place in the race to the Masters because 16th-placed Ryan Day beat Thepchaiya Un-Nooh 6-3 with a top run of 81.

Northern Ireland Open champion Mark Williams extended his winning streak to nine consecutive matches with a 6-2 win over Andrew Higginson.

Mark Allen came from 3-2 down to beat Oliver Lines 6-4 with top breaks of 101 and 127. That ended Lines' hopes of playing his dad Peter in the next round.

Chinese teenager Lyu Haotian made a 106 in a 6-3 win over former world champion Peter Ebdon. Enditem
