Kilkenny’s David Morris won his opening match at the UK Championship in York but Ken Doherty is out.

Former world snooker champion Doherty was beaten 6-5 by John Astley, ranked world number 99.

"It's a huge win and the biggest of my career so far," said Astley, from Gateshead. "I was nervous but felt I coped quite well."

Morris progressed to the second round after a 6-4 win over Stoke’s Jamie Cope.

Meanwhile, world number 15 Ali Carter hit out at the new format for the tournament despite a routine first-round win.

Two-time World Championship finalist Carter cruised past Thailand's Ratchayothin Yotharuck 6-1, but was unhappy with the cramped conditions at the Barbican and the prospect of having to come through seven games to win the tournament.

"It's not for me, this flat draw. I don't think the venue can accommodate it," he told BBC Sport.

"It's hard to believe that if you are in the top 16 you would be in favour of this. We all had to come through the old system. We all started off at the bottom and got to the top so I don't see why doesn't everyone else have to do that."

Despite Carter's complaints, though, there were few alarms for the big names in action in Thursday's first two sessions.

Stuart Bingham and Barry Hawkins were 6-0 winners over Ahmed Saif and Alexander Ursenbacher respectively, while Graham Dott dropped only two frames to Fraser Patrick.

Shaun Murphy, champion in 2008, had an even easier day with a walkover after Lee Spick's withdrawal.

Veterans Jimmy White and Nigel Bond joined the qualifiers.
