Northern Ireland Open: Mark Selby beats Xu Si 4-2 in first round
Mark Selby beat Xu Si of China 4-2 in the first round of the Northern Ireland Open at the Waterfront Hall on Monday.
Selby won the first frame with a break of 78 but his opponent took the next two, before missing a simple black which would have taken him two clear.

As the winner of the English Open, Selby is the only player who can lift a £1m bonus for winning all four tournaments in the Home Nations Series.
The three-time world champion beat David Gilbert 9-1 in the final of the English Open in Crawley last month, with the Scottish Open to come in December and the Welsh Open in February.
