Wilson

During the 2009–10 season, Wilson won the sixth event of the International Open Series having already finished runner-up in the third event, and he finished the season fifth in the rankings. This gave Wilson a place on the World Snooker Tour for the 2010–11 snooker season. In the UK Championship he defeated Paul Davison 9–6 and Ian McCulloch 9–8, before losing 4–9 to Rory McLeod in the third round. He reached the same stage of the World Championship qualifying with defeats of Dermot McGlinchey and Joe Swail, before McLeod once again conquered Wilson this time 10–3 in the third round of qualifying. He finished the year ranked world number 72 and did not retain his place on tour. Wilson entered the 2011 Q School to win back his place on Tour, but was unable to do so.

Having dropped off the Tour, Wilson was considered an amateur player and could not enter qualifying for any of the ranking events. He entered 12 of the Players Tour Championship (PTC) events and finished 72nd on the Order of Merit. He entered the 2012 Q School but only won one match over three events. In the 2012–13 season, Wilson was again confined to entering amateur events and enjoyed a good run in the PTC Event 4 by beating Tom Ford, Jamie Jones and Stephen Maguire, before being whitewashed 4–0 by Ding Junhui in the last 16. He also lost in the last 32 in two European Tour events to be ranked 75th on the PTC Order of Merit. He then turned professional in 2013 for the 2013–14 season.

Wilson enjoyed a successful return to the professional game during the 2013–14 season. He won four matches in Shanghai Masters qualifying, concluding with a 5–3 victory over Marcus Campbell to reach the main stage of a ranking event for the first time. In his first round match against Stuart Bingham, Wilson had a chance to make a 147 but missed the 13th black. Nevertheless, he defeated his much higher ranked opponent 5–1 and continued his run with a 5–3 win over Marco Fu. Wilson's tournament came to an end in the quarter-finals as he lost 1–5 against Michael Holt. He caused another upset in the first round of the International Championship by beating Stephen Maguire 6–3, before losing 1–6 to Graeme Dott in the second round.

His momentum continued into the evening, and he took the last four frames of the match, including three breaks over 50, to win 10–7. In anticipation of playing his first match at the Crucible, Wilson described it as a "dream come true" and said that he would like to draw Ronnie O'Sullivan in the first round. Dott stated that Wilson could "beat anybody" if he played to the same standard again. Wilson played world number 12 Ricky Walden in the first round of the championship, losing 7–10 after a final frame that lasted for over an hour.

After edging Gary Wilson 6–5 in the first round of the UK Championship, Wilson stated that his concentration had been fading in matches this season and would have to raise his game significantly against defending champion Neil Robertson. He did exactly that as he made an 87 break to lead 5–4 and had a chance to win in the next frame courtesy of a fluked red, but lost position on the final brown allowing Robertson to level. In the decider Wilson missed a tough opening red and Robertson responded with a match winning 86.

After losing in the semi-finals of the 2015 Snooker Shoot-Out, Wilson had his best finish of the year in a ranking event as he dropped just one frame in his victories over Alan McManus and Ben Woollaston at the Indian Open.

He was visibly emotional during his semi-final victory and later apologised to McGill for having won the match on a fluke.

He played Ronnie O'Sullivan in the final. The first session was of poor standard, possibly due to both players reeling from narrow victories in their semi-finals, both ending with a deciding frame. Wilson trailed 2–6 after the first session and 2–8 in the second, but found form to reduce his deficit to 7–9.
