An attacking batter, Knight gained nation-wide recognition following her exploits in the 2013 Ashes series victory.
She played for Devon as early as 2005, aged 14, and has also featured for both the Diamonds and Rubies in the Super 4s Twenty20 competition.
Knight was the leading run-scorer in the 2009 Women's County Championship and her performances earned her an England academy inclusion and then a call-up to the senior tour of India in place of the injured Sarah Taylor during February 2010.
She made 49 on England debut during a one-day international in Mumbai and that November was given a T20 international bow versus Sri Lanka in Colombo.
During England's tour of Australia in January 2011 she posted 72 at the WACA and on the same trip went on to make her Test debut.
Knight continued to feature for England and struck 55 not out to complete a one-day whitewash of South Africa in Potchefstroom that October.
She continued to be an ODI regular during 2012 and helped England finish third at the 2013 World Cup in India.
Knight was named player of the series in the 2013 Women's Ashes. Her 157 in the Test at Wormsley was vital in an England draw and she went on to score 140 runs in the limited-overs matches. Her performances earned her a nomination for the Sunday Times sportswoman of the year award.
That winter she helped England retain the Ashes Down Under, making fifties in two consecutive ODIs.
In the 2014 summer a hamstring injury prevented her occasional seam bowling so she became an off-spinner with some success for England.
After England failed to regain the Ashes at home in 2015, Knight and the rest of the side would bounce back with 2-1 ODI and Twenty20 series victories over South Africa in early 2016.
Knight produced match-winning innings in the penultimate match in both series, hitting an unbeaten 67 in Johannesburg and a brisk 25 to guide England to victory.
