Top-ranked American Sofia Kenin loses, then says she'll pass on the Olympics. So which U.S. players are competing?

WATCH: From earlier this month, Coco Gauff speaks about the possibility of qualifying for the U.S. Olympic team.

UPDATE, July 1: The Tokyo Olympics tennis rosters were officially revealed, with the United States being represented by:

• Men's singles: Tommy Paul, Frances Tiafoe, Tennys Sandgren, Marcos Giron
  Women's singles: Jennifer Brady, Cori Gauff, Jessica Pegula, Alison Riske
  Men's doubles: Rajeev Ram/Frances Tiafoe, Austin Krajicek/Tennys Sandgren
  Women's doubles: Cori Gauff/Nicole Melichar, Bethanie Mattek-Sands/Jessica Pegula

The question sounds simple, but it's proven to be a challenge to answer: which Americans will travel to Tokyo to compete in this summer's Olympic Games?

Qualifying for the four available men's and women's spots—based on the respective tour rankings—ended two weeks ago, but the players are still making individual decisions on whether they'll commit to the travel and time required.

But with each passing Wimbledon press conference, we're seemingly getting closer to resolution.

Just before the tournament, we learned that Serena Williams won't be on the team. At the time, that was a personal choice—for reasons she chose to withhold—but given her mid-match retirement on Tuesday, she might not have been healthy enough, anyways.

Her sister, ranked 111th in singles but owning four Olympic gold medals, was not expected to be up for selection. She confirmed as much in this highly entertaining press conference, following her first-round win:

On Wednesday, Venus lost her second-round match (to Ons Jabeur), as did compatriot Sofia Kenin. The highest-ranked U.S. player, period, Kenin was assured a spot on the team if she wanted it.

But after her 6-2, 6-4 loss to fellow American Madison Brengle, Kenin revealed that travel restrictions ultimately led her to pass on the opportunity:

So, who is—potentially—going to the Olympic Games for the USA? Nick Zaccardi, writer for NBC Sports and formerly in the tennis space, gave the most succinct prediction (again, all subject to change):

For the women:

• Jennifer Brady (No. 15)
• Coco Gauff (No. 23)
• Jessica Pegula (No. 26)
• Madison Keys (No. 27)

For the men:

• Tommy Paul (No. 52)
• Frances Tiafoe (No. 57)
• Tennys Sandgren (No. 68)
• Marcos Giron (No. 74)

UPDATE: The above rosters have been confirmed by the Associated Press with the exception of Madison Keys, who will be replaced by Alison Riske (No. 29)
