Claycourt master Rafael Nadal quickly adapted to the new surroundings at Roland Garros with a 6-2 6-1 6-3 demolition of German qualifier Yannick Hanfmann in the first round of the French Open on Monday.
Loud screams of frustration at the start of the second set seemed to have a cathartic effect, with Williams finding her stride soon after.
After dropping the first set, she was in danger of suffering just the second opening round defeat of her Grand Slam tournament career.
Williams said the mid-match outfit change didn't have anything to do with the temperature, though.
At last year's French Open, Williams wasn't only trying to make a fashion statement when she wore the outfit that she called her "Wakanda-inspired catsuit", referring to the fictional nation in the film "Black Panther". But she didn't look up to her best, either, by any means. In what was her first Grand Slam tournament since giving birth to her daughter nine months earlier, they were a precaution after a health scare related to blood clots.
Sure, the bad backhand put her behind only 15-30 at the outset of the second set of her opening match at Roland Garros on Monday.

After committing 14 unforced errors in the first set, Williams had a total of 10 in the second and third sets.

Serena Williams of the USA reacts as she plays against Russia's Vitalia Diatchenko during their women's singles first round match on day two of The Roland Garros 2019 French Open tennis tournament in Paris on May 27, 2019. She had played only nine matches all season, and so her pursuit of a record-tying 24th Grand Slam title - fourth at Roland Garros - is no sure thing. For context, her sea-green catsuit she wore in Melbourne in January for the Australian Open was called "Greatest". Her movement wasn't ideal, and she often reached for shots instead of thumping them.
During an error-filled first set, Williams was constantly shaking her head and yelling at herself.
