season came in Warsaw at the PTC Event 6, where he beat Ricky Walden 4–1 in the final. This success was quickly followed up by another PTC title in Event 8 where he won by a 4–1 scoreline again, this time against Judd Trump. Victory ensured that Robertson maintained his record of never having lost in a ranking event final. He would later finish third in the Order of Merit and therefore qualify for the 2012 PTC Finals. His fine form continued into the UK Championship in York, where he beat Tom Ford, Graeme Dott and Ding Junhui en route to his first semi-final in the event.
