Judd Trump took a potshot at Mark King after an agonising final frame defeat to the Londoner at the Maplin UK Championship yesterday.

The Keynsham potter was upset with his opponent's constant swearing during the match, an offence which usually results in a warning from the referee and even the deduction of a frame.

In extreme circumstances a player can even lose the match if he has been warned for swearing on more than one occasion.

But match official Leo Scullion refused to discipline King who, despite his bad behaviour, clinched a dramatic 9-8 victory.

"He was getting frustrated and swearing during the match," said Trump. "He shouldn't be doing that.

"He kept swearing every time he played a bad shot, every time someone said 'come on Judd'.

"It was silly of him. It didn't really put me off, but it just made me want to beat him.

"He didn't get warned once, he should have lost the match really. He swore at least 10 times."

Trump pocketed breaks of 87, 44, 40, 52 and 48 to force the decider having trailed 6-3.

But despite his best efforts the 19-year-old, a semi-finalist at this season's Royal London Watches Grand Prix, lost out on the final pink ball in the final frame.

"I played all right when I was coming back, I didn't feel any pressure until I was coming back," he added.

"I had a chance in the last frame to win it, but I missed the final pink and rattled it over the pocket.

"I should have won really, he got really lucky in the last frame. I had him at 8-7, he was missing a few, so it's just frustrating.

"I played terrible both days, but I still should have beaten him 9-8.

"I wouldn't say he was the better player, he had more chances and more luck."

Meanwhile, five-time champion Stephen Hendry also made a first-round exit as Stephen Lee claimed his scalp.

Hendry, ranked sixth in the world, won his first UK title in 1989, and successfully defended it the following year before reeling off three in a row from 1994 to 1996.

The Scot has been a UK finalist three times since being crowned champion for a fifth time, but Lee made sure he would embark on a run to the final in 2008 with a 9-7 victory.

He went 8-7 up with a century break and confidently sealed victory in the next as Hendry failed to force a decider.

Lee, who has suffered a dip in form and results over recent seasons, said: "I'm hitting the ball really well and it's just nice to be part of it.

"I'm feeling quite good under pressure and it's just a matter of enjoying it again."

Lee pondered quitting snooker after his first-round exit from the World Championship in April, but the 34-year-old from Trowbridge is relishing his future in the sport again.

"I've started to enjoy it again," he said. "To beat Stephen, I'm over the moon.

"Enjoyment is what it's all about. I wouldn't do it if I didn't like it. I would have probably found something else to do with myself."
