• Allen wins five frames in a row against Mark Williams

• Zhao Xintong cruises to 6-2 win over Gary Wilson

Mark Allen shrugged off a bout of food poisoning to beat Mark Williams 6-2, winning five successive frames, and book a Masters quarter-final with Judd Trump or Ding Junhui, who play on Wednesday.

Speaking to the BBC, Allen, the 2018 champion, said: “I prepare properly for these events, but I couldn’t prepare for this at all as I’ve been lying in bed all week with food poisoning. I just thought: ‘Go out there and give my best.’ I wouldn’t have had much left if it had got much closer.”
