SCOTLAND's Michaela Tabb will referee this year's World Championship final in Sheffield on May 6 and 7.

The Glaswegian has been a professional snooker referee since 2001 and officiated her first Crucible final in 2009, between John Higgins and Shaun Murphy.

"I was absolutely elated when I found out I was doing it again this year," admitted the 44-year-old. "I loved it when I did the final in 2009. It went really well for me without any mistakes so I just hope it will be the same this time.

"It's such a huge tournament with a lot of history and potentially hundreds of millions of people watching on television. There's no venue like the Crucible in terms of the atmosphere. When it falls silent it is so intense."

Tabb is one of the most successful female officials in sport, and has paved the way for more female snooker referees, including China's Zhu Ying who has established herself on the pro circuit this season. "It's amazing to see the difference between now and when I started, when refereeing was dominated by men," added Tabb.

This year's World Championship starts later this month and will feature 32 of the world's best players battling for prize money of £1.1m.
