...The tournament will also see Michaela Tabb become the first female referee to take charge at the Masters.

Tabb will add another chapter to her refereeing CV
Tabb, who caused a stir at last year's World Championship, will referee two matches, including the meeting between Steve Davis and Ken Doherty on Tuesday.

"I'm really looking forward to refereeing at the Masters for the first time," said Tabb.

"I know the atmosphere at Wembley is electric and it will be great to experience that."
