Fit-again Ali Carter upset four-time world champion John Higgins with a 4-2 victory in the first round of the PTC Grand Finals in Galway.
Carter, who could not take part in last month's Haikou World Open due to complications with his Crohn's disease, sealed a place in the last 16 with the win on Wednesday.
He took advantage of a missed red to make a 79 clearance in the first frame before Higgins made it 1-1 with a run of 111.
Carter then made it 3-1 and 4-2 to progress.
"I've been really struggling with my Crohn's disease and haven't been able to practise much so it's a big win for me," said Carter.
"I just dug in today and it was a good performance. The first frame was massive, it's hard to clear up from 60 behind, especially against John Higgins.
