Next January, as Williams bids for a third consecutive grand slam triumph, Keys will be hoping to make an impact at just her third major tournament after qualifying for the Australian Open.
The American, now 17, earned a wildcard for 2013's first grand slam by beating compatriot Mallory Burdette in the final of a qualification event in Atlanta, Georgia.
"It'd be great to go to Australia and not get killed in the first round this year," Keys, ranked 137 in the world, told the WTA Tour's official website.
