Serena Williams withdraws from Rogers Cup

Serena Williams has pulled out of next week's Rogers Cup in Montreal for "personal reasons", tournament organisers have announced.

The Wimbledon runner-up suffered the worst defeat of her professional career in San Jose earlier this week when she won just a single game against Johanna Konta.

"I know I can play a zillion times better, but I have so many things on my mind, I don't have time to be shocked," said Williams after the match.

Rogers Cup tournament director Eugene Lapierre said in a statement: "Of course, we are disappointed that Serena will not be joining us. Fans were very much looking forward to seeing her in action.

"But, beyond the disappointment, the tournament as a whole remains a high-level competition. The entire top 10 is here, along with 22 of the top 25. There are exciting matches in store from the outset."

Williams is replaced in the main draw by Germany's Tatjana Maria, who will take on Alize Cornet of France in round one.
