Serena Williams has left the door open for future tournaments after putting on an emphatic display during her first round singles victory at the US Open.
The 40-year-old announced earlier this month that the US Open would very likely be her last tournament, but she will have at least one more match at Flushing Meadows after casting aside Montenegrin player Danka Kovinic 6-3, 6-3.
For now Williams has everyone guessing if she will retire after the US Open as she potentially hinted otherwise in her post-match press conference. She said: "I've been pretty vague about it, right. I'm going to stay vague because you never know."
