ASHEVILLE, NC, USA - Though the result didn't matter in the end in more ways than one, Serena Williams made her official return to competitive tennis in Fed Cup on Sunday.

The former World No.1 partnered sister Venus in doubles for the first time since the Rio Olympics in 2016 to close out the World Group Quarterfinal tie between the United States and the Netherlands at US Cellular Arena.

The 14-time Grand Slam doubles champions were defeated by Demi Schuurs and Lesley Kerkhove, 6-2, 6-3 in a dead doubles rubber. 

Earlier, Venus defeated Richel Hogenkamp, 7-5, 6-1 to give the United States an unassailable 3-0 lead in the tie and send the U.S. into April's semifinals against France. 

Another victory by Venus over Arantxa Rus and a win by CoCo Vandeweghe over Hogenkamp on Saturday helped give the United States a 2-0 lead after the first day of play.

Sunday's match marked Serena's first appearance in Fed Cup play since the World Group Playoffs in 2015, in which she contested three rubbers and the United States was defeated by Italy in Italy, 3-2. 

Sunday's match marked the second time that the 23-time Grand Slam singles champion has taken the court for a tennis match of any kind since the birth of daughter Alexis Olympia Ohanian, Jr. in September, but the first which counts officially on her record.
