(Reuters) - Spain's former world number 1 and Wimbledon and French Open champion Garbine Muguruza announced her retirement at a news conference on Saturday, making the extended break she had announced a year ago a permanent step.

Venezuelan-born Muguruza won the French Open in 2016 and Wimbledon in 2017, and she reached the final of the Australian Open in 2020. Last April she said she would take a break from competition to spend more time with her family.
