Masters debutant Yan Bingtao caused a huge upset as he came back from 5-3 down to shock World No 2 Neil Robertson in the first round.
Former world champion Robertson led 3-1 and 5-3, but couldn't close out the match as Bingtao battled back and secured an impressive 6-5 win after over four hours of snooker.
The 20-year-old will next face either Mark Selby or Stephen Maguire, who meet from 7pm on Tuesday evening.
