Campbell is most famous for
whitewashing Stephen Hendry 9–0 in the 1998
Liverpool Victoria UK Championship, one of the most surprising results in snooker's history. He followed this win with a 9–6 win over
Quinten Hann in the last 32. He started the 2007/2008 season strongly by reaching the last 16 of the
Grand Prix, coming through the qualifiers and beating players like
Graeme Dott and
Anthony Hamilton before his run ended in a 5–2 defeat to
Joe Swail. He also reached the last 32 of the
Welsh Open where he beat
Lee Spick,
Ricky Walden and
Gerard Greene and gave
Ding Junhui a run for his money before Ding eventually won 5–4. He qualified for the
2008 Bahrain Championship before scoring a 147 in his wildcard match against Ahmed Basheer Al-Khusaibi. He lost to eventual champion
Neil Robertson in the last 32. He then qualified for the 2010 World Championship, where he lost 10–5 to Mark Williams. Campbell won the first professional tournament of his career in Germany when he won Event 3 of the
Euro Players Tour Championship beating
Liang Wenbo 4–0 in the final. This result along with other consistent performances were enough to see him enter the top 32 in the rankings. He also qualified for the world championship for the second successive year, where he played
Shaun Murphy. He subsequently lost 10–1 to Murphy. In the
2011–12 season Campbell qualified for six of the eight ranking events. His best results of the season were last 16 exits at the
Australian Goldfields Open, where he lost 1–5 to
Mark Allen, and at the
World Open, thanks to
Ali Carter withdrawing from the event, before being defeated by
Graeme Dott 3–5. He played former champion
Matthew Stevens in the first round of the
UK Championship, despite the death of a close friend just a few hours before. Stevens won the match 6–2. Campbell played in all 12 of the
PTC events, making two quarter-finals in
Event 1 and
Event 3, to finish 30th in the
Order of Merit, just out of the top 24 who made the
Finals. Campbell played
Liang Wenbo in the final qualifying round for the
World Championship and produced two comebacks in the match having trailed 2–8 and 5–9 to level at 9–9, before the match was delayed to let the evening session's order of play begin. Liang had time to compose himself and won the decider to end Campbell's season, which he finished ranked world number 25. The
2012–13 season began very well for Campbell as he qualified for the
Wuxi Classic, where he reached the first ranking event semi-final of his 21-year professional career. He dispatched
Stephen Lee,
Fergal O'Brien and
Mark Williams to play
Ricky Walden in the semis. He lost the match 1–6 and stated afterwards that he "didn't feel comfortable at all" and put it down to nerves. However, he also felt that winning a ranking tournament was now within his reach. He qualified for four of the next seven ranking events, but lost in the first round on each occasion. Campbell missed opportunities in the first session to finish it 2–7 behind and went on to lose 4–10. Campbell was ranked world number 28 at the end of the season. Campbell lost in the first round to local favourites in the first two ranking events he qualified for in the
2013–14 season. In the
Australian Goldfields Open it was
Neil Robertson who eliminated him 5–1 and at the
Indian Open he lost 4–1 to
Pankaj Advani. At the
UK Championship Campbell saw off
Lü Haotian and
Michael White, but was then beaten 6–2 by
Ronnie O'Sullivan. Campbell could not advance beyond the first round in any of the remaining ranking events and suffered a surprise 10–4 defeat to
Alex Borg in
World Championship qualifying, a player who had until then only won three matches all season. He has not played in an event since. == Performance and rankings timeline ==
