Mark Selby fought back to win the final two frames and beat Jackson Page 4-3 to book his place in the last 16 of the World Grand Prix in Hong Kong.
World number three Selby had found himself 3-2 down after Welshman Page made a break of 85 to move one away from victory.
After Page missed a long red, Selby, a four-time world champion, made the most of his chance to take the sixth frame 75-37 and then closed out the decider.
"Jackson played well to go 3-2 up and I was just hanging on," Selby said on the World Snooker Tour website.
"He had a good chance to win 4-2, but luckily he let me back into it. I will need to improve in the next round."
Elsewhere in Wednesday's morning session at the Kai Tak Arena in Kowloon, Neil Robertson made breaks of 97 and 67 as he coasted past Yuan Sijun 4-0.
The Australian feels a switch to a titanium ferrule ring on his cue tip has helped reignite his passion for the game.
"As soon as I wake up I am thinking I can't wait to practice, and it's the first time I have felt that in over 20 years," said Robertson, who made the change after the Welsh Open.
"The things I am doing in practice are exciting. I need to experience it more in an area with the different cloth, but once I fully adapt I will be playing some fun snooker."
Xiao Guodong compiled two tons in a 4-3 comeback win over Jak Jones, the Welshman having recovered from 2-0 down with three half-centuries of his own.
