Trump beats Ronnie

Trump, 22, raced into a 4-0 lead going into the mid-session interval, which included a tremendous 140 break.

The four-time champion came out and rallied, winning two out of three frames and scoring a 141 break, the highest of the tournament so far.

But Trump held his nerve with a 65 break in the eighth frame, and will face Neil Robertson or Mark Williams.

Trump came into the tournament as UK champion, having beaten Mark Allen 10-8 in last month's final.

And the man from Bristol said he felt the result was never in doubt.

"I came into the tournament full of confidence thinking I can win it and all the other players want to beat me," he said.

"I didn't miss many balls [although] I got a little impatient towards the end to try and get over the winning line, but Ronnie had the crowd on his side.

"He has done what few in the game have done and I look up to him."

Three-time world champion O'Sullivan reciprocated the praise, saying of Trump: "Judd scored heavily and played a fantastic match. He put in some good breaks under pressure.

"All you can do is sit there and hope for your chance but it's difficult to stop someone with so much confidence.

"I couldn't give any more out there and he played better on the day."

A nervous opening frame saw both players miss opportunities, with O'Sullivan failing to sink an easy cut on the black off its spot. He was duly punished by his opponent who knocked in a break of 39 to clinch the frame.

O'Sullivan found himself snookered from the break-off in frame two and missed the reds, leaving world number five Judd a free-ball, from which a 66 break gave him the frame.

With play proceeding at a frantic pace and Trump taking every chance that came his way, he was soon 3-0 ahead and the 22-year-old looked a picture of composure as he notched a tournament highest-break 140 in the fourth.

O'Sullivan's 67 in the next got him on the board, and preserved his record of never having been whitewashed at the Masters.

Trump, who also defeated O'Sullivan at the UK Championship last month, emerged victorious from a tactical battle in the sixth frame to lead 5-1 but his opponent was not going down without a fight, and was cheered on by the boisterous London crowd as he stroked in a 141 clearance, snatching the tournament's highest break from Trump by a single point.

But he broke down on 54 in the next frame and Trump held his nerve with a 65 break go through.
