Career
Born in 1969, Giles turned professional in 1992. At the 1993 World Championship, qualifying for which was held near the start of the season, Giles defeated Tessa Davidson 5–3, Stan Haslam 5–1, Paul Maskell by the same scoreline, Barry Bunn 5–2, Simon Haggerty 5–0, Jamie Woodman 5–2, Andrew Cairns 10–2, Tony Meo 10–9, John Campbell 10–3 and Tony Knowles 10–6 to reach the last 32 stage - the first round at the Crucible Theatre. In the event, Giles could not replicate his stellar form in his match against Steve James.
He held James to 1–3 but came to trail 1–9.
Reaching the Crucible earned Giles £8,000, but his best performance the following season was a run to the last 96 of the 1993 United Kingdom Championship, where he lost 1–5 to a resurgent Alex Higgins. In spite of his poor form, Giles reached his highest ranking, 108th, for the 1994/1995 season.
Giles progressed to the last 96 at two ranking events the following season. At the 1994 United Kingdom Championship, he lost 4–5 to Danny Fowler, and at the 1995 British Open, Steve Newbury defeated him 5–2.
Some success came in 1995/1996.
Giles reached the last 32 at the 1996 Welsh Open, defeating Hugh Abernethy, Joe Jogia, Les Dodd and Martin Clark before being whitewashed 5–0 by Drew Henry. The following season, Giles met Steve Davis in the last 64 at the 1996 Grand Prix, where he lost 2–5. Having lost his professional status at the end of the 1996/1997 season, Giles entered ten qualifying events to regain it for the following season, and was successful.
However, he dropped off the tour once more in 1999, aged 29.
