Yan Bingtao overcame a slow start to claim a 4-1 win over Xu Si to reach the second round of the Welsh Open.
The Chinese star had not been seen in competitive action since beating John Higgins to win the Masters on January 17.
He looked rusty at the start and Xu struck early to raise the prospect of an upset, but the 21-year-old snuffed out the threat in impressive fashion with a couple of century breaks.

The second frame was similarly scratchy, but a half-century from Yan levelled the contest.
The third frame saw Yan go through the gears, and a break of 127 secured him a cushion in the match.
