London - Venus and Serena Williams have been fined $4 000 each at Wimbledon for skipping a news conference after their loss in the doubles quarter-finals.
Serena Williams said on Thursday she was "shocked to hear" about the penalty, adding she and her sister rarely speak to the media after Grand Slam doubles matches other than finals.
The top-seeded Americans lost to Russians Vera Zvonareva and Elena Vesnina in three sets on Wednesday.
Serena Williams will play Zvonareva in the singles final on Saturday.
