Lines gathered enough wins during the 2013/14 season to keep his place on the main tour, finishing 61st in the world rankings.
He reached the last 16 of the Wuxi Classic, winning three matches before losing to Matthew Stevens, and the same stage of the Shanghai Masters, recording four victories before being knocked out by Xiao Guodong.
Lines had previously stated that his biggest remaining ambition was to play on the main tour at the same time as his son Oliver, and his wish was granted as Lines jnr booked his place on the circuit for 2014/15. They are the first father and son duo on the tour since Geoff and Neal Foulds.
Lines enjoyed a phenomenal run at the 2009 UK Championship, matching the best performance of his career by reaching the quarter-finals.
He had to win three matches just to get to the venue, beating Xiao Guodong, Ian McCulloch and Nigel Bond. Lines then hammered Marco Fu 9-3 in Telford before scoring the best win of his career with a 9-8 victory over twice World Champion Mark Williams.
"I'm delighted, over the moon," said Lines. "I've been playing here like I do in the qualifiers. I was nervous at the start today but once I had a frame on the board I settled down. I've struggled over the years against the lower ranked players, but when you play the top boys you have nothing to lose."
That was the end of his run, however, as he lost 9-5 to Stephen Maguire.
Lines' career was turned around by coach Steve Prest, who rescued him from the secondary circuit and helped him finish second in the 2007/08 Pontin's International Open Series rankings. Sadly, Prest died in 2009.
"It's devastating," said Lines. "We turned pro at the same time and we'd been mates for 23 years. I can't put into words how much of a loss it is. He started coaching me when I was on the PIOS a couple of years ago. I was contemplating giving up snooker but he turned my game around and I got back on to the pro Tour."
Lines reached his first ranking quarter-final at the 1999 China Open in Shanghai. He beat John Higgins 5-1 in the first round proper and Peter Ebdon 5-4 in round two before going out to Brian Morgan.
Lines reached the Crucible stage of the World Championship for the first time in 1998, losing 10-3 to John Parrott in the first round.
