The Masters: Neil Robertson eliminates Ronnie O'Sullivan to reach last four

Robertson's top breaks were 119 and 130, and he will now face either Mark Williams or John Higgins in the semi-finals.

Neil Robertson gained revenge by knocking out Ronnie O'Sullivan to reach the semi-finals of the Masters.

The Australian defeated O'Sullivan 6-4 to book his spot in the last four and knock out the seven-time champion.

The pair were playing in a rematch from December's Grand Prix showdown in Coventry where O'Sullivan beat Robertson 10-8 to claim the title.

O'Sullivan mustered just one century in the match but still levelled at four frames apiece, before Robertson pulled away.

Robertson's top breaks were 119 and 130, and he will now face either Mark Williams or John Higgins.

"I know how much a Masters crowd can really carry a player, my Masters debut was against Jimmy White," Robertson told the BBC.

"So it was important I was able to hit back against him. I knew I was going to hit the ball well today.

"You never know what the result's going to be, but I knew I would hit the ball well.

"I pulled off some brilliant pressure shots and gained momentum from that. It's nice that I can still pull out the recoveries when I need them."

O'Sullivan lamented the middling standards of both players, but refused to offer any excuses despite biting the tip off his cue straight after his defeat.

"It wasn't, really, good stuff; I didn't play good, he didn't play good," O'Sullivan told the BBC.

"Both of us were queueing alright. I was just trying to make it as competitive as I could, and trying to give the crowd and give Neil a bit of a game."

Asked about problems with his cue tip, O'Sullivan added: "I never make any excuses, Neil was the better player today.

"Hopefully he goes on and wins it. I like Neil, he's a good man."
