Bex Field, the 22-year-old who plays for the Norfolk indoor club in Norwich, has added another major honour to her growing list of achievements.

At Nottingham on Saturday, she claimed the senior national women's indoor singles title to go with the junior version she lifted last year, and became one of the youngest players ever to win the competition.

Field's success encapsulates the changing face of bowls. This weekend, the combined age of the four semi-finalists in the women's singles was, quite astonishingly, 82, with a trio of 22-year-olds and one remarkable sixteen-year-old – John Rednall's daughter Katherine Rednall, from Ipswich.

Field opened her bid for the title with a 21-9 win over Tamworth's Sharon Barlow, and clinched her place in the semi-finals by beating Wellingborough's Tina Broderick.

In that match, she had to show a great deal of resilience – after trailing for the whole match, she finished strongly with a 1-1-2-1-2 sequence to turn a 14-19 deficit into a 21-19 victory.

When she trailed Rednall in the semi-finals, 4-10, her chance seemed to have gone, but she clawed back into contention, and scored 17 shots to five on her way to a brave 21-15 win.

The final was a close-fought low-scoring affair until the tenth end, when Copeland led 6-5, but once again, Field showed her finishing power, scoring 16 shots to her opponent's three, and winning with a flourish, taking a full house on the 20th end to win, 21-9.

'I can't believe I've won it,' Field said, as she accepted congratulations from her coach and mentor, Di Wilson, who travelled from Boston in Lincolnshire to give her support.

Kent's Perry Martin, who is only 19, created a record when he became the first player to win the men's national junior and senior titles in the same season, when he beat Surrey's Paul Coleman, 21-15, in the final.

Gallow star Mervyn King looked on course to win the men's title – until his bid was derailed by Commonwealth Games bronze medallist Graham Shadwell, 21-15, at the quarter-final stage.
