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.

Belinda Bencic reached a first Wimbledon semi-final as she beat Mirra Andreeva in straight sets on Centre Court. Seventh seed Andreeva had been the firm favourite, with the 18-year-old up to this point not dropping a set on her impressive run to the quarter-finals.

Belinda Bencic, playing in her first Wimbledon quarterfinal in nine appearances at the All England Club, upset Russian teen sensation Mirra Andreeva 7-6 (3), 7-6 (2) on Wednesday to reach her second Grand Slam semifinal and first in six years.
