Early career Craigie qualified for the
2011/2012 Main Tour after winning the 2010 IBSF World Under 21 Championships. He defeated his brother
Stephen 7–6 in the semi-finals before beating
Li Hang 9–8 in the final to secure the title.
2011/2012 season In his
debut season on the snooker tour he was unranked and therefore needed to win four qualifying matches to make the main draws of the ranking events. He won two matches in attempts to reach both the
Australian Goldfields Open and
German Masters respectively and had his best set of results in qualifying for the
China Open, where he beat
Adam Wicheard,
Liu Song and
Gerard Greene, before losing to
Ricky Walden 3–5 in the final round. Craigie played in 11 of the 12 minor-ranking
Players Tour Championship events throughout the season, with his best finish coming in
Event 11 where he was defeated by Walden again, this time in the last 16 by 4 frames to 2.
Following years Craigie played in two events in the
2012/2013 season, but could only pick up one frame. He did not enter an event in the following season, but did play in
2015 Q School, coming closest to rejoining the tour in the first event when he was defeated 4–2 by
Adam Duffy in the last 32.
2016/2017 season In 2016, Craigie received a two-year
tour card for the
2016/2017 and
2017/2018 seasons after successfully qualifying through the EBSA Play-Offs in
Sheffield, beating
Adam Duffy 4–3 in the last round of the event. He qualified for the
World Open with a 5–3 victory over 1997 world champion
Ken Doherty and won his first match in a main draw of a ranking event by beating
Marco Fu 5–3 in the opening round. Craigie was then edged out 5–4 by
Matthew Selt. Craigie made a century and two fifty plus breaks to whitewash
Jamie Jones 4–0 at the
Northern Ireland Open, before
John Higgins made a 147, 137 and 130 in a second round 4–1 defeat. Craigie was 3–1 ahead of
Mark King at the interval of their first round match at the
UK Championship and that quickly became 4–1 when King was docked a frame for forgetting his cue at the resumption of play. Craigie went on to win 6–2, but in the second round lost 6–5 to
Luca Brecel after leading 5–3.
Shaun Murphy knocked Craigie out of the
Shoot-Out and in the second round of the
Gibraltar Open. He dropped off the tour at the end of the 2017/18 season but entered
2018 Q School in an attempt to win back a place. He defeated former crucible semi-finalist
Andy Hicks in round 3 of the first event and beat
Dechawat Poomjaeng in the final round to secure his return to the tour at the first event.
2018/2019 season In April 2019, he reached the quarter final of a ranking event for the first time at the
China Open after beating the likes of
Ryan Day,
Ali Carter and
Liang Wenbo before being whitewashed by
Neil Robertson.
2019/2020 season Craigie's best result for the season was reaching the Last 32 of the
Riga Masters after beating Long Zehuang and
Jamie O'Neil before losing 4–3 to
Matthew Selt.
2020/2021 season Craigie qualified for the
World Snooker Championship for the first time after beating
Ashley Hugill,
Hossein Vafaei, and
Zhao Xintong in the qualifying rounds. He drew
Mark Williams in the first round. ==Personal life==
