2017 UK Championship

Jimmy White defeated Ali Carter in the first round, despite being more than 100 places lower in the rankings.

The first round saw few upsets, with most of the highest ranked players progressing.[9] However, Ding Junhui (second seed) was defeated by world number 130 Leo Fernandez 6–5, despite having led 5–1, and having a chance to win the match in frame 7.[10] Fernandez had only recently returned to the professional circuit after serving a 15-month ban for a corruption charge.[11] Elsewhere, Ali Carter (11th seed) lost 6–2 to Jimmy White (118). Despite Carter having been ahead 2–1, White won the next five frames to progress.[12][13] Another upset saw Lyu Haotian (104) defeat Anthony Hamilton (25) 6–1.[14]

The second round of the tournament was played from 2–3 December and began with defending champion, and world number one Mark Selby losing to Scott Donaldson (64) 3–6.[10] Donaldson had lost all 10 matches of his season prior to the tournament, won six of the last seven frames to win the match, having trailed 0–2.[15][16] The remaining top 16 players progressed through the second round, with the lowest ranked player to proceed being Lyu – ranked 104 – who defeated Peter Ebdon 6–3 to reach the third round.[14]

Lyu Haotian ranked 104 defeated Marco Fu, Anthony Hamilton and Peter Ebdon to reach the fourth round.

Round three was played between the remaining 32 players, from 4–5 December 2017, seeing more top 16 players be defeated. Graeme Dott (30) overcame Judd Trump (3) 6–2, despite trailing 2–0. Dott compiled five 50+ breaks, and won the next six frames.[17] Hoatian who had defeated Hamilton and Ebdon in prior round, defeated Marco Fu (8) 6–4.[14][17] Both Neil Robertson (9) and Mark Williams (16) were also defeated at this stage, 5–6.[17] Robertson was defeated by Mark Joyce (41), and caused him to miss the 2018 Masters, after dropping out of the top 16, thanks to the loss.[17] Sunny Akani (87) whitewashed Barry Hawkins (10) 6–0, with Hawkins commenting after the match that he was "in a state of shock" with the result, commenting on both Akani's performance, and the poor playing conditions.[18] Williams lost to fellow Welshman Ryan Day (17), having been ahead at 4–1.[17]

Round four saw the remaining sixteen players play from 6–7 December 2017. Only four top 16 seeded players reached the last 16 of the tournament – John Higgins (4), Shaun Murphy (5), Mark Allen (6) and Ronnie O'Sullivan (7).[19] This was the fewest top 16 seeds to reach that stage in the tournament's 40-year history.[20] Higgins played Mark King (21), where he was defeated 5–6. King trailed at both 2–4, and 4–5 but won the match despite making a highest break of just 69.[21] Murphy would defeat Ricky Walden 6–1, with Walden only winning frame four.[22] Mark Allen lost to Joe Perry (22) 6–4.[23][24] O'Sullivan played Sunny Akani in this round, winning the match 6–5, despite being 4–5 behind. O'Sullivan commented after the match that he felt as though he had "robbed" Akani of the win, describing him as being unlucky.[22]

The quarter-finals took place on 8 December 2017 on two tables. Shaun Murphy completed a 6–1 victory over Mark King.[25] Post-match, both Murphy and King commented on the audience, with a man being removed for snoring and a woman for talking during the match.[26] Ronnie O'Sullivan defeated Martin Gould 6–3, after leading 5–0.[27]

O'Sullivan won the event, defeating Shaun Murphy in the final 10–5, winning the last five frames in a row.

Stephen Maguire defeated Joe Perry 6–3 to set up a semi-final match with O'Sullivan, in a repeat of the 2007 UK Championship final. After beating Maguire in 2007, O'Sullivan commented that Maguire would "dominate for a decade". Reacting to the match from 10 years prior, Maguire stated that O'Sullivan "talks some bollocks", having not dominated the game since that match.[28][29] Ryan Day also overcame Mark Joyce in a deciding frame 6–5.[30]

The semi-finals were played on 9 December 2017. The first semi-final saw O'Sullivan defeat Maguire 6–4. O'Sullivan took a 4–0 lead at the interval, before Maguire won four of the next five frames, with O'Sullivan winning the match in frame ten.[31] The second semi-final saw Shaun Murphy overcome Ryan Day 6–3. Murphy would take a 5–1 lead, before losing the next two frames, and winning the match in frame nine.[32]

The final was played as best of 19 frames, over two sessions on 10 December 2017. Both O'Sullivan and Murphy had met in the final of the 2017 Champion of Champions the month prior, with Murphy winning 10–8.[32] Murphy and O'Sullivan would share the first session 4–4, despite Murphy being behind at 2–4.[33] In the second session, O'Sullivan put together six 50+ breaks including two centuries to win six of the next seven frames to win the match 10–5, winning five frames in a row.[34][35]

Post match, pundit John Parrott described O'Sullivan as "a genius of a juggernaut", commenting on the impressiveness of the clinical win.[34][36] The win would be O'Sullivan's sixth UK Championship victory equalling that achieved by Steve Davis, and his 18th Triple Crown victory overall,[37] equalling the record set by Stephen Hendry.[38][39]
