World champion Stuart Bingham reached the last 16 of the China Open with a 5-3 win over Ian Burns.
Bingham, who will begin the defence of his Crucible title next month, won the last two frames to see off Burns.
A break of 90 in the final frame got Bingham over the line and set up a meeting with Rod Lawler in the next round.
"Ian's a tough opponent, I had to work really hard," Bingham told worldsnooker.com.
"I had four breaks over 50 so I'm pleased with the way I played.
"There are only a few top-16 players left but that shows how much class there is lower down the rankings."
Stephen Maguire kept alive his chances of an automatic Crucible spot by beating Jack Lisowski 5-2.
The Scot needs to reach the semi-finals to have a chance of being one of the top 16 players in Sheffield.
A break of 101 helped Maguire build a 4-0 lead over Lisowski and he went on to seal victory in frame seven.
"The top-16 situation is at the back of my mind but it doesn't add any extra motivation for me because I try hard in every match anyway," he said.
"I'm just trying to take one match at a time, and if I don't make it it's my own fault."
Maguire will face Dominic Dale in the next round after the Welshman knocked in two centuries as he beat teenager Darryl Hill 5-3.
World number seven Judd Trump continued his Crucible preparations by taking just 72 minutes to see off Jimmy Robertson 5-1.
John Higgins swept past Mark Joyce 5-1 and Graeme Dott sank 15-year-old amateur Yuan Sijun 5-2.
But a third former world champion, Shaun Murphy, lost a 3-2 lead to bow out 5-3 against Mark King.
