The Welshman is one of the highest-profile names to crash out so far.
Ryan Day exited the English Open on Tuesday after a 4-3 defeat to Lu Ning in the qualifying round at the Metrodome in Barnsley.
The three-time ranking event winner and reigning Shoot Out king won the opening two frames but surrendered the next three to move to within the brink.
Day managed to force a deciding frame, but Ling, a semi-finalist in last year’s UK Championship, compiled a break of 57 in the last to edge through this English Open contest.
Two other encounters required all seven frame before the outcome was determined with Scott Donaldson and Martin O’Donnell both booking their spots at the venue stages courtesy of narrow wins.
Donaldson and O’Donnell each withstood comebacks from 3-1 down to negotiate their respective opponents Ian Burns and Lyu Haotian with 4-3 scorelines.
The other encounters on day five were mostly one-sided affairs with Martin Gould, Tian Pengfei, and Oliver Lines all managing to advance with 4-0 victories.
Joe O’Connor lost just a frame in overcoming Pang Junxu while Hossein Vafaei also secured a 4-1 triumph as he ousted Kurt Maflin.
On Wednesday, the preliminary action for the English Open concludes with the likes of Stephen Hendry, Jimmy White, and Ken Doherty entering the fray.
The top 16 in the world rankings enter this year’s English Open in the same round as everybody else, but their matches have been held over to the Marshall Arena in Milton Keynes.
