Belinda Bencic advanced to the semifinals in just her second Grand Slam since since returning from maternity leave, upsetting Mirra Andreeva through a pair of tiebreaks Wednesday at Wimbledon.

After major champions Victoria Azarenka and Serena Williams returned to play after giving birth in 2017 and 2018, it seemed to usher in something of a baby boom on the WTA Tour. The WTA even introduced a new maternity leave benefit earlier this year. There were nine mothers in the main draw at Wimbledon this year.

Iga Swiatek has reached the Wimbledon semifinals for the first time with a 6-2, 7-5 victory over 19th-seeded Liudmila Samsonova that went from a stroll to a bit of a struggle in the late stages.
