Captain Kathy Rinaldi’s roster released Wednesday also includes Sofia Kenin, Jessica Pegula and Jennifer Brady.

The matches are April 20-21.

The winner will return to the top-tier World Group in 2020 with a chance to win the Fed Cup title. The loser will drop down to World Group II next season.

The U.S. is 8-0 against Switzerland in the Fed Cup, but the nations’ most recent meeting came in 1993.

The No. 8-ranked Stephens was the 2017 U.S. Open champion and No. 14 Keys was the runner-up there. Kenin, Pegula and Brady are all also ranked in the top 80.

Switzerland’s roster has no one ranked higher than No. 81 Viktorija Golubic.
