The second set was a bit one-sided though, as the Estonian raced to a 4-0 lead rather quickly. Bencic did well to get one of the breaks back, but it was too little too late.

Kontaveit soon secured another break of serve and then closed out the match without much trouble. She'll go up against Jelena Ostapenko in the semifinals.
