At least she was able to pay back Weinhold.

Moving On

Stollar won her first-round match in Charlottesville against Carol Zhao in straight sets. She stayed at the club through the afternoon, mingling with the other players, most of whom she knew, and worked out again with Rodriguez. The next day was Rodriguez’s birthday, and Stollar, with the help of the hotel’s reception desk, ordered a special gluten-free cake for her coach.

Then she took an Uber car back to her room at the Homewood Suites, where she had a typical night on the road talking to her mother and friends on FaceTime. Rodriguez went out and brought back sushi, Stollar’s favorite, and had it sent to her room.

But the next day, Stollar lost to Claire Liu in straight sets. Her mother, ever intent on her daughter’s progress, watched nervously on a live-stream feed from their home outside Budapest, and then immediately called a travel agent to arrange Stollar’s next flight. Within an hour, Stollar and Rodriguez had received email confirmations from a Hungarian travel agent for their flights back to Boca Raton, Fla., where Stollar was training and staying with Rodriguez’s family.

Their flight left before Rodriguez’s birthday cake was ready.

“It’s too bad,” Stollar said. “But you know, we can’t change all our plans for a cake.”

By then, Wozniak was already on her way back to Montreal. She lost in the first round at Charlottesville — also to Liu — with a half-dozen people watching, including her host, Stephanie Scheel. For Wozniak, staying in the free housing was the only sensible choice.

“She was such a nice guest,” Scheel said. “She even did her own dishes.”
