Former world champion Shaun Murphy went out of the Welsh Open after losing a final-frame decider against fellow Englishman Barry Pinches in round one.
Pinches, 53, was a late call-up for the event and needed snookers in the final frame, but he came through 4-3 against the 2020 Welsh Open winner.
The result means Murphy will miss next week's Players Championship in Telford, an event he won last year.
Robert Milkins, who beat Murphy in last year's Welsh final, ousted Jamie Jones.
Welshman Jones made breaks of 72, 136 and 70 to lead 3-2 but Milkins hit back to progress, also by a 4-3 margin.
Three-time world champion Mark Williams secured his place in the second round as the Welsh great posted a 4-2 win over John Astley.
In the evening session current world title holder Luca Brecel of Belgium scored 93 - his top break of the game - as he survived a scare in beating China's 18-year-old Jiang Jun 4-3. Jun made a 101 break to hit back after going two frames down, but it was not enough.
Scotland's John Higgins hit a final-frame break of 118 as he eased passed Egypt's Mohamed Ibrahim 4-0, while Kyren Wilson beat fellow Englishman Ashley Carty 4-3.
In a late night finish England's Mark Selby completed a tense 4-2 win over China's Yuan Sijun to progress.
Earlier China's Ding Junhui, who won this tournament in 2012, beat England's Jenson Kendrick 4-2.
Ding's compatriot Zhang Anda, ranked 13th in the world, saw off American Ahmed Aly Elsayed 4-1, while world number 17 Jack Lisowski beat fellow Englishman Oliver Brown 4-2.
Barry Hawkins compiled a break of 142 - the highest in Llandudno so far - on his way to a 4-0 win over He Guoqiang, while Welshman Alfie Davies beat Scotland's Liam Graham 4-1.
Mark Allen put together a 101 break as he also progressed in a 4-3 win over China's Cao Yupeng.
