Robertson won the 2012 Masters by defeating Shaun Murphy 10–6 in the final. He beat Mark Allen and Mark Williams in the opening two rounds, before facing Judd Trump in the semi-finals for the second successive major tournament. He exacted revenge for his defeat in York a month earlier by winning 6–3 and said after the match that he had been spurred on by fans cheering when Trump fluked shots. Such was Robertson's feeling that he lacked support from the local crowd, he offered to buy a pint of beer for anyone attending his matches in an Australian hat or shirt, but only one person heeded this call in his semi-final match against Mark Williams. In his first Masters final he opened up a 5–3 lead over Murphy in the first session and, although he lost the first frame upon the resumption of play, won four frames in a row to stand on the edge of the title. Despite a brief fightback from the Englishman, Robertson secured the frame he needed with a break of 70 to become the fourth man from outside the United Kingdom to win the event.
