The play on main stadium was started with a match between Danielle Collins and Dalma Galfi. The American was supposed to play against Tamara Korpatsch, but the German withdrew on Wednesday's afternoon because of the illness and got replaced by Galfi, who not passed the qualies despite being a top seed there. The Hungarian utilized her lucky-loser chance brilliantly, making a huge upset on Collins who was condifent pre-match favorite. Galfi won 6-4 6-4, utilizing a really bad day in the office for Collins, who was coming back to a good form, achieving the semifinals in last week's WTA 250 ATX Open. "Danimal" was clearly off today, looking like not feeling well on court, making a big amount of unforced errors with unusually low quantity of winners (just 8 to 47 UFEs in whole the match). Galfi was pretty reliable on serve and used the weaknesses of her opponent, taking the initiative in rallies and winning last 4 games of second set. The Hungarian came back from being down 2-4 in second set and managed to achieve a straight set win against the best ranked and recognisable player in her career so far. Caroline Garcia will be the next opponent for the world's number 80.

Sofia Kenin earned her biggest victory since struggling with health issues and coming back to competition on top level, defeating Sloane Stephens 6-4 6-1 in confident style. The Australian Open 2020 champion was a dominant force in one of the most interesting all-American matchups on the main stadium today. Stephens started better with an early break, but Kenin gave her no chances since leveling the score in first set, producing 10 breakpoints and converting 4 of them in general. Kenin will set up the very interesting matchup against Elena Rybakina - another one between the Grand Slam champions.

Emma Raducanu came back to competition despite still dealing with wrist's injury issues. The Brit has performed really well against Danka Kovinic, advancing into 2nd round with a win 6-2 6-3. Raducanu came back from being 0-2 down in both sets and dominated the game in general, scoring the series of 6 games won in a row in first set and 4 in second. Magda Linette is the next stop for Raducanu.

Peyton Stearns lives a big dream two weeks in a row. The NCAA 2022 champion, who earned her first ever WTA level victories in last week's ATX Open, where she achieved QFs as a wild-card receiver, god another WC into the biggest tournament in her life so far. The young American did not waste it, prevailing this year's WTA 250 Auckland runner-up Rebeka Masarova, coming back from being a set down and winning 4-6 6-4 6-4. Stearns will play against Bianca Andreescu in next round.

Thiem was already up 6-4 4-1 with a single break in second set, but the Frenchman came back to match and forced decider.
