Woollaston's second professional title was Event 3 of the Players Tour Championship in the 2011–12 season. He defeated former World Champion Graeme Dott 4–2 in the final. His performances in the other 11 PTCs, including a quarter-final run in Event 8, saw him claim ninth place in the Order of Merit and therefore qualify for the 2012 Finals. It was the first time he made it to the main stages of a ranking event since 2007. He played Ding Junhui in the opening round and lost 2–4. Woollaston also qualified for the 2012 China Open by winning three qualifying matches, concluding with a 5–4 victory over Ryan Day. He played Ding again in the first round of the event, and looked to be on course for a shock result as he led 4–0 at the interval in the best-of-nine frame match. However, Ding found his form, and won five successive frames to take the match 5–4. His season concluded with a 3–10 loss to Dominic Dale in the final qualifying round for the World Championship and he finished ranked world number 43, meaning he had risen 26 places from the start of the season, the most of anyone on the tour.
