Two more semi-final appearances in March 2019, at the Players Championship and the Tour Championship, were followed by the biggest success of Trump's career so far, when he won the 2019 World Championship. He defeated Thepchaiya Un-Nooh 10–9 in the first round, having trailed 3–6 after the first session. In the second round against Ding Junhui, he led 5–1 and trailed 7–9, then won six consecutive frames to clinch a 13–9 victory. A comfortable 13–6 quarter-final win over Stephen Maguire took him to the semi-finals, where he beat Gary Wilson 17–11 to secure his second appearance in a world final.
