US Open champion Serena Williams will be joined by Maria Sharapova at the 2013 Brisbane International.
Tournament organisers announced Williams and Sharapova have been added to the women's draw for what will be a key warm-up event for the Australian Open.
Williams will arrive in Brisbane for the tournament, which begins on December 30, as the winner of the two most recent majors.
She added the US Open crown on Monday (AEST) to her Wimbledon victory in July.
The 30-year-old, who also won the Olympic singles gold medal in London, contested Brisbane this year where she reached the quarter-finals prior to withdrawing with an ankle injury.
World number two Sharapova has enjoyed success in 2012 as well, having won her maiden French Open in June.Tags: sport, tennis, brisbane-4000 First posted September 13, 2012 13:31:01
