A notable upset has already occurred at the 2012 Wimbledon tournament, which opened with first round competition Monday. Russian Elena Vesnina dispatched notable American Venus Williams in straight sets, 6-1, 6-3. The loss marks another early elimination for Williams, who was knocked out of the 2012 French Open in the second round.

Vesnina closed out the match with an ace, which exemplified how dominant she was in the match. Williams has struggled to move through singles tournaments as of late, consistently dealing with injuries that caused her to pull out of several tournaments in 2011.

On the men's side of the tournament, No. 1 seeded Novak Djokovic cruised through his opening round match against Juan Carlos Ferrero, 6-3, 6-3, 6-1. Djokovic is looking to rebound from his loss in the finals of the 2012 French Open to Rafael Nadal.
