Walden began the season by winning his second ranking event title at the Wuxi Classic. He beat amateur Zhu Yinghui in the first round 5–0 and was leading Joe Perry 4–0 and by 64–0 in the fifth frame, before Perry incredibly went on to level the match.&lt;ref name="2012/13"&gt;&lt;/ref&gt; The deciding frame came down to the final black, with Perry missing and Walden potting it at 1am local time, to reach the quarter-finals. He defeated Robert Milkins 5–3 and comfortably beat Marcus Campbell 6–1 in the semi-finals to play in his second career ranking final, where he faced Stuart Bingham. Walden raced into a 7–1 lead in the first session, despite Bingham's solitary frame being a 147, and would return to close out a 10–4 victory. Following this he lost in the first round of the Australian Goldfields Open 4–5 to Jamie Cope and in the second round of the Shanghai Masters 2–5 to Mark Williams.
