Serena and Venus Williams will be back on court, separately, to play for a spot in the Wimbledon final.

Serena, a six-time champion at the All England Club, will be first on Centre Court against Elena Vesnina in the semifinals. Following that match, five-time Wimbledon champion Venus will take on Angelique Kerber.

The winners will play in Saturday's final.

But Serena and Venus won't be done after their singles, and neither will Vesnina. The American sisters will play in the doubles tournament on No. 2 Court later Thursday, taking on Vesnina and Ekaterina Makarova in the quarterfinals.
