World No.1 Serena Williams has warned the rest of the women's tennis that there is more to come from her after being named WTA player of the year for the fifth time overall.
According to Sport24, Williams enjoyed one of the greatest seasons in 2013 in WTA history.
She won 78 of 82 matches, the US Open and French Open among 11 titles, and a record 12,385,572 dollars in prize money, the report said.
Since February, she's been the oldest No. 1 in WTA history and is now 32, the report added.
Serena said that she has some areas where she can do a lot better for the next year and look forward to it, adding that overall she remembers the wins, but she also wants to learn from her mistakes and not repeat them.
Williams was also player of the year in 2002, '08, '09 and '12, the report further said.
