Radio Report:
Aussie Katherine Hull (pictured left) - who started the day back down the field in joint 8th place on 2 under - hit an incredible round of 66 (6 under par) to finish the day 8 under par and 4 shots behind runaway leader Yani Tseng at the end of round three.
Taiwanese Tseng saw her overnight lead of 6 whittled down to 2 at one stage but moved back to 4 ahead thanks to an eagle on the 18th hole.
Korea's In-Kyung Kim finished in 3rd place on 6 under par. The weather remained fine for most of the day, allowing the top players to flourish - Christina Kim picked up 2 shots to finish on 4 under, level with 4 other players while Brittany Lincicome picked up one shot to finish up on 5 under par.
When asked about the secret of her good performance today Tseng admitted that she had undertaken some personal coaching during the week and, as a result, resorted to singing a Taiwanese song in her head to help keep relaxed and focus during the game.
Tseng has only dropped one shot in 3 rounds of the Birkdale course in this competition so it is hard to see her being overtaken as things stand - but the weather could still play an important part in tomorrow's exciting climax to the 2010 Ricoh Women's British Open.
