Bingham shocked in Chengdu
In-form Stuart Bingham headlined the surprise first-round casualties at the International Championships in Chengdu on Tuesday.
After a clinical showing in the Premier League last week, where he won his two games 12-0 on aggregate, Bingham was expected to go deep into the draw, only to have his path blocked by little-known Indian Aditya Mehta.
The 26-year-old, in his first ranking event, was a 6-4 winner, booking a second-round meeting with Judd Trump, who looked in good touch as he beat Fergal O'Brien 6-3, with a 118 the highlight.
Joining Bingham on a flight home was fourth seed Mark Williams, who was impressively beaten by Mark Davis.
The 40-year-old from St Leonards was a 6-4 winner over the two-time world champion, sealing the success in style with a clearing 138.
He went 3-0 ahead against an off-colour Williams, who stayed in things at the interval with a 74.
He should have made it 3-2 having got in with 57, only for Davis to return to the table and scrape a close one, before Williams responded with a clinical 80.
But Davis, who is looking to move into the top 16 this week, edged to 5-2 and, despite Williams fighting to 5-4, he held his nerve to see things out with the highest break of the tournament so far.
"I played really well, although I made a few silly mistakes," the Six-Red World Title winner told worldsnooker.com.
"Mark is a legend of the game but he was not at his best today. It's a long season and you can't play well in every event."
Elsewhere, Stephen Maguire won his all-Scottish clash with Jamie Burnett 6-3.
The China Open runner-up, who will now face the man who beat him in that event, Peter Ebdon, was in fine touch as he racked up scores of 73, 93, 102 and 118.
"I felt a lot of pressure today because I've been here a few days, it's along way from home and you don't want to go out early," said Maguire.
Mark Allen is also through to the next round, top-scoring with 124 as he got past Robert Milkins 6-2.
His next match will be against Cao Yupeng, the player he accused of being dishonest at the World Championships in April. Cao beat John Higgins in the first round.
The morning's other session saw Marco Fu beat Martin Gould by the odd frame in 11, while in the evening, Ding Junhui crushed Zhou Yuelong 6-1 and Ricky Walden got the better of Lu Ning 6-4.
With the first round completed, as well as the Mehta-Trump, Ebdon-Maguire Allen-Cao match-ups, the last 16 will see clashes between Lu Haotian and Dominic Dale, Matthew Stevens and Neil Robertson, Shaun Murphy and Ding and Walden and Mark Selby.
