Serena Williams: Threat to sue Wimbledon was 'heat of the moment'

"What I say on the court, whether it's smashing my rackets, or... it's in the heat of the moment."

Serena Williams promised she would never sue Wimbledon after making a "heat of the moment" threat during a fourth-round win over Svetlana Kuznetsova.

The six-time women's singles champion was unhappy with the suggestion she and her Russian opponent should play on at 5-5 in the first set, after light drizzle fell on Centre Court.
