Tennis News : British tennis player Johanna Konta retires

Long-time British number one Johanna Konta has announced her retirement from tennis.

The 30-year-old has struggled with a persistent knee problem over the past couple of years and has slipped to 113 in the rankings.

Born in Australia to Hungarian parents, Konta moved to Europe to pursue her tennis career as a teenager, settling with her family in Eastbourne and becoming a British citizen in 2012.

A relatively late developer, Konta's emergence at the top of the game began in 2015, and the following year she reached her first grand slam semi-final at the Australian Open and climbed into the top 10.

Her best season was arguably in 2017, when she became the first British player since Virginia Wade to make the semi-finals at Wimbledon, won the biggest of her four career titles at the Miami Open and peaked at fourth in the rankings.

Konta slipped down the rankings in 2018 but was resurgent the following year, making another grand slam semi-final at the French Open as well as quarter-finals at Wimbledon and the US Open.
