“Mark Allen reached the semi-finals of the Riyadh Season World Masters after a dramatic victory over Mark Selby. The match went down to the final black, when the Northern Irishman showed his nerve to double into the middle pocket and claim a 4-3 victory. He had earlier looked set to make a swift exit from the tournament, after the Jester eased into a 3-1 lead, only to blow several victory chances.”
