*Serena Williams reached her seventh Wimbledon semi-final today by beating China’s Na Li 7-5, 6-3.

The win on Centre Court came shortly after older sister Venus was knocked out earlier by Bulgaria’s Tsvetana Pironkova, spoiling chances of an all-Williams final.

Serena had 11 aces during the match, won 85 percent of her first-serve points and only double faulted once. She has now garnered more than double the amount of aces than any other female in the tournament.

Li, an accomplished player on grass, had 19 unforced errors in comparison to Serena’s six. Li also double faulted five times. Serena broke Li’s serve four times throughout the match.

With Venus and reigning U.S. Open champ Kim Clijsters having been eliminated Tuesday, Serena is the heavy favorite to win Wimbledon. Other than Serena, there are no players left in the Wimbledon field seeded in the top 20.
