Stephens went 11 months between tournaments because of surgery on her left foot in January, returning to competition at Wimbledon in July.
Her ranking was 934th before she reached consecutive semifinals at hard-court tournaments in Toronto and Cincinnati in August.
Her only previous trip to the final four at a major tournament came at the Australian Open four years ago.

The No. 12 seed leads No. 29 seed Diego Schwartzman of Argentina 6-4, 6-4.
