Once a trickster, always a trickster...

Serena and Venus Williams go after their sixth Wimbledon title together.

"I feel like I lost it and he won it for sure," says seven-time Wimbledon champion of semifinal loss.

The Swiss maestro took a tumbled during the fifth set of his Wimbledon semifinal and ended up losing a critical break shortly thereafter.

"Pretty much our job is to make the impossible happen every day," says five-time champion.
