Perry's good play continued into 2014 as he advanced to the quarter-finals of the German Masters with the loss of just three frames, but he then lost 2–5 to Ding Junhui. He secured a very impressive 5–1 win over Selby in the quarter-finals of the Welsh Open, stating that his new found casual approach to the game was a key reason to his successful season. However, it was Ding who once again halted his run in a ranking event as he beat Perry 6–4. A sixth quarter-final appearance of the season came at the PTC Finals, but he lost 2–4 to Judd Trump. He fought back from 3–6 down after the opening session of his first round match with Jamie Burnett at the World Championship to win 10–7 and set up a second round clash with reigning champion Ronnie O'Sullivan. Perry started the better of the two as he established a 5–3 lead after the opening session and maintained his two-frame advantage after the second, although he missed a chance in the final frame to be 10–6 ahead. He went on to lead 11–9, before O'Sullivan leveled the match and then made back-to-back century breaks to win 13–11, with Perry remarking afterwards that he had been "blown away by a genius" in the last few frames.
