At Wimbledon Saturday, Serena Williams won 19 of her first 20 service points, and hit 20 aces in her straight-sets win over Dominika Cibulka, 6-0, 7-5. The 20 aces is a tie for her own personal best, which also happens to be the highest number on record there by a woman. "Serving that well feels awesome," Williams said. "I serve well at Wimbledon for some unknown reason. I want to keep doing it. I wish I could serve like this every tournament." Later, Spanish favorite Rafael Nadal beat Germany’s Philipp Petzschner in five sets.
