Brazil's other women's team of Agatha and Barbara - the defending world champions - will play Russian Federation.
But the tweet directed at Walsh Jennings, a 38-year-old with three Olympic gold medals and three young children, highlights more than just annoyingly routine commentary about female athletes' apparel. In the end, it was a Brazilian beach party, and the US queens of midnight Rio volleyball saw their quest for gold end.
Plus there was this gem, in which Walsh Jennings went under the net to make the play.
Ross said the surprise appearance defines what she loves about the Olympics - that all members of Team USA support each other.
It was the third time in four Olympic matches that Walsh Jennings and Ross were slotted for the midnight match the better to showcase them on American television.
In the men's bracket, Brazil's Alison and Bruno Schmidt will look to win gold when they take on Italy's Paolo Nicolai and Daniele Lupo Thursday night. We have Agatha and Barbara in two days and we are so excited. On the beach, Walsh Jennings and Ross will face Brazil's pair of Agatha Bednarczuk and Barbara Seixas De Freitas in the semifinals.
The match started out strongly for the Americans, who capitalized on several unforced errors to jump to an early lead.
Walsh Jennings had never lost an Olympic beach volleyball match before tonight. Heidrich and Zumkehr were able to get back within a point, but were unable to get back in it completely.
But the other Brazilian team needed three sets and 70 minutes - the longest of the Olympics so far - to get past Switzerland in the afternoon. "They deserved to win, but we gave them a really, really hard win".
Following Monday's win, Walsh Jennings was asked whether she is thinking about winning gold. "I don't want anyone to not play because they don't want to wear the uniform".
Just when we thought her story was ending, she keeps adding new chapters.
