Ronnie O'Sullivan then competed in the International Championship, cited as the biggest event in Asia, in Chengdu after beating James Cahill to qualify. Having battled to beat Ben Woollaston 6–4, in his opening match of the tournament, Ronnie sailed past his next two opponents, McGill and Li Hang, 6–1. This set up a meeting with Mark Williams, a man who had not beat O'Sullivan for 12 years, in the quarters; however, after falling 3–0 behind, Williams won the next 5 frames and eventually the match, 6–5. O'Sullivan next competed in the Champion of Champions where he was defending champion. O'Sullivan begun his defence with a 4–2 defeat of Stuart Bingham. He then went on to whitewash Marco Fu 6–0 to reach the semi-final. In the semi-final, O'Sullivan defeated Ding Junhui 6–4 and then went on to defeat Judd Trump in a high-scoring final, 10–7, making four century breaks and eleven breaks over fifty during the match. On 4 December 2014, O'Sullivan completed his 13th career maximum break in the fourth round of the UK Championship, against Matthew Selt. Three days later he won his fifth UK Championship, coming through 10–9 against Judd Trump in the final. After trailing 1–5 and 4–9, Trump won five frames in succession, before O'Sullivan prevailed in the deciding frame despite playing with a broken ankle, having broken it the previous week whilst running.
