Career
Born in 1968, Gill turned professional in 1991. He first made progress in a ranking event at the 1993 Asian Open, where he beat Craig Harrison, Andy Hicks and Jason Whittaker before losing 4–5 to Ian Graham in the last 96. He also reached the last 128 at the 1993 World Championship, losing 9–10 to Robert Foxall.
The 1993/1994 season brought some success for Gill, with a run to the last 64 at the 1993 United Kingdom Championship.
At the 1994 World Championship, Gill defeated Peter McCullagh 5–1, veteran Ray Edmonds 5–3, Steve Judd 10–6, Jonathan Birch 10–7, Matthew Couch 10–8 and Mark Bennett 10–7 to qualify for the main stages at the Crucible Theatre for the first time. Gill next progressed beyond the last-96 stage of a tournament during the 1995/1996 season, when he reached the last 64 at both the United Kingdom Championship and the World Championship.
Having begun the 1996/1997 season ranked 97th, a career-best, he finished it with a 5–10 defeat to Barry Pinches in qualifying for the 1997 World Championship. Pinches would be eliminated in the last 64 but both he, ranked 83rd, and Gill, the world number 120, lost their places on the professional tour at the season"s conclusion.
That season"s only highlight was a run to the last 96 at the 1999 Thailand Masters, where Pearce beat him 5–2.
After competing as an amateur for two years, Gill reached the final of a United Kingdom Tour event in 2000, losing 4–6 to Adrian Rosa, and entered the professional tier once more for the 2001/2002 season. Finishing the season ranked 116th, he was relegated once more from the tour, aged 34. Attempts to re-qualify the following season proved unsuccessful, although Gill reached the second qualifying round of the 2005 World Championship, where Martin Gould defeated him 5–2.
