The middle-order batsman and off-spin bowler made her debut against South Africa in the summer of 2003 and was voted NatWest Player of the Match in the first ODI, taking 3-21.
Consistently strong performances with bat and ball helped seal back-to-back series victories against South Africa and she has developed into a useful all-rounder for England.
Rosalie has a BA (Hons) Degree in Linguistics from Sussex University, plays for Sussex CCC and attends Sussex CCC cricket academy. She also works as a junior cricket coach and for the marketing and media department at the Hove ground.
She was selected in the 15-strong squad for the Women's World Cup in South Africa in 2005 and took 3-29 in the first one-day match against the hosts in preparation for the start of the tournament.
She picked up impressive bowling figures of 2-14 during England's second match of the championship - a 214-run victory over Sri Lanka - but was unable to prevent England from being knocked out at the semi-final stage by favourites Australia.
She made one appearance during the NatWest Women's Series against Australia in the summer of 2005 and played in the first npower Test at Hove, where she took two wickets, during the Ashes series which England won 1-0.
She was selected for the winter tour to Sri Lanka and India, with Clare Connor absent due to injury, and enjoyed a more regular place in the side.
She seized the opportunity with both hands, taking eight wickets in two ODIs against Sri Lanka as England won the series 2-0.
She claimed her best figures for England when she took 6-24 in a warm-up match against India A and took three more wickets in the drawn Test against India in Delhi, but could not prevent a 4-1 defeat in the ODI series.
She did not play international cricket for a year, but was recalled to the squad for the 2008 tour of Australia and New Zealand in 2008 as England aim to retain the Ashes.
