While the match was no classic, those fans who had taken a break after the conclusion of the Dominic Thiem-Novak Djokovic men's semi-final which had caused the women's final to run more than an hour late, missed some of the more thoughtful tennis played on the Roland Garros clay this past fortnight.
Amanda Anisimova, a 17-year-old rising tennis star, has just shot to fame after defeating Simona Halep, who is now ranked as the number three player (formerly number one) easily in just two sets, which lasted a little over an hour at the French Open.
Barty led 5-0 in the first set and lost it, while a similar fate befell Anisimova in the second despite the American establishing a 3-0 lead.
Barty broke Vondrousova on all three of her service games in the first set and twice more in the second, smacking 27 winners past the Czech teenager.
"Pretty tough to come to terms with", Barty said of her first-set collapse.
"I surprised myself, maybe, how deep I got in this tournament and how well I actually was able to play throughout", Federer said.
"At the end of the day, I did make it to the semifinals for the first time".
Barty came through a weird three-set semi-final against American 17-year-old Amanda Anisimova, who put out defending champion Simona Halep in the last-eight. I'm a tennis player through and through.
Her giant-killing ways saw the American breeze into the semis without losing a set.

Louis Federal Reserve President James Bullard said in a speech that a rate cut may be needed "soon". Ultimately, a risk premium may increase the real cost of borrowing for all USA based investments.
However, in a ideal capsule of the unpredictable semi-final, played out in front of a half-full Court Suzanne Lenglen, Barty claimed the next six games to level the tie.
Cash regularly often watches Barty's matches with the Queenslander's coach Craig Tyzzer, admitting he's an unabashed fan of the Australian magician. My job is to come here and entertain people, and I feel I did that.
Now she has gone a step further by becoming the first Australian since Margaret Court in 1973 to win a Roland Garros singles title.
"She didn't let me play my game", Vondrousova said.
Barty began as well as possible, racing to a 5-0 lead within 12 minutes by winning 17 of the first 18 points.
Born to Russian parents who emigrated to the United States in 1998, Anisimova started to play tennis when she was just three.
The Czech teenager is now the number 38 in the world but she's sure to climb the rankings, regardless of whether she triumphs on Saturday.
Moments later, with Anisimova serving at 15-40, Barty held two sets points.
The world number 51 rattled off five consecutive games to draw level and another sloppy forehand from Barty gave Anisimova the chance to serve for the set.
"Hopefully we can continue to create those opportunities and let kids know that this is an option for a career and they can enjoy it".
