 Maflin won three matches to reach the final round in qualifying for two of the first five ranking events of the 2012/2013 season.These came in the Wuxi Classic where he lost in a deciding frame to Michael Holt, and the International Championship where he lost 2–6 to Mark Davis.He took advantage of the new flatter qualifying system used in the German Masters, whereby he would only need to win two matches to progress to the main stage in Berlin, by beating Joel Walker and Tom Ford, dropping only a single frame in the process.
