Serena and Venus Williams Serena and Venus Williams were each fined $4,000 at Wimbledon for skipping a news conference after their loss in the doubles quarterfinals.

Serena said Thursday she is “shocked to hear” about the penalty, adding she and her sister rarely speak to the media after Grand Slam doubles matches other than finals.

Serena and Venus were the doubles top seeds at Wimbledon. They lost to Russians Vera Zvonareva and Elena Vesnina in three sets Wednesday, 3-6, 6-3, 6-4.

Serena will play Vera in the Wimbledon singles championship on Saturday. That doubles loss will surely be on her mind. Will the revenge factor give Serena extra momentum, or will it be a negative to hinder her game? It will be interesting seeing how the match plays out.
