Neil Robertson delivered a remarkable fightback against Mark Williams to secure his place in the final of the Masters. The 39-year-old Robertson trailed 3-1 and then 5-3 before taking the best-of-11 encounter at Alexandra Palace to a finale with a brilliant break of 119 in the 10th frame. The Australian then required two snookers in a nail-biting decider, the second of which he duly received when Williams, who was 29 clear with 27 remaining, hit the green as he tried to swerve for the yellow. The final frame turned into a fascinating tactical battle with, at one point, the black and the final red together on the edge of a corner pocket, with both players trying not to knock the black in. The Welshman, 46, who was aiming to reach the final 19 years after he lifted his second Masters crown, showed he can still compete at the highest level. But Robertson, who has won the Masters title only once – beating Shaun Murphy a decade ago – held his nerve to cross the finish line and claim a 6-5 victory. Fighting back tears, the world No 4, who will face either Judd Trump or Barry Hawkins in Sunday’s showpiece final, said: “Never give up, never ever give up. It doesn’t matter how it looks. “To have a match that finishes like that, you will probably never see that ever again in the sport. It was absolutely incredible and it is going to take some hours for that to sink in. It has to be one of the best comebacks of my career. “The tension was so high and I played a really good snooker on the yellow. The green was one of the best pressure balls I have ever knocked in in my career. And I managed to hold myself together at the end.” He added: “I almost feel as if I have got nothing to lose because I was out of the tournament, so it might make me a bit of dangerous man tomorrow.”
