his best snooker to reach the final of the Masters by defeating Ali Carter 6–1 in the quarter-finals and Ronnie O'Sullivan 6–1 in the semis. The latter victory marked the first time O'Sullivan had been eliminated at that stage of the event after 10 previous wins, and also ended a run of 15 consecutive wins in all competitions. However, in the final Robertson suffered the heaviest defeat in the Masters since 1988, as Shaun Murphy thrashed him 10–2. Next month, Robertson did not lose a frame in reaching the quarter-finals of the German Masters, but when he accidentally potted the black in the deciding frame, Stephen Maguire got the two snookers he required and went on to clear the table to win 5–4. At the Welsh Open, in his fourth round match against Gary Wilson, Robertson was forced to concede the fifth frame when he failed to hit a red three times in a row, then lost the next frame to exit the tournament.

Despite this, Robertson, who had won four ranking titles since his world title in 2010, stated that he believed he had underachieved in his career. 2015–16 season Robertson exited in round one of the first two ranking events in the 2015–16 season, and lost 6–4 to Mark Selby in the quarter-finals of the International Championship. He then claimed his first major title in over 12 months by beating Mark Allen 10–5 in the final of the Champion of Champions. At the UK Championship, in their third round match, Thepchaiya Un-Nooh missed the final black for a 147, before Robertson made a 145 break in the next frame and went on to win 6–2.
