If Carlos Alcaraz was surprised by the resistance he faced in the first round, he has to be downright shocked now. 

The 2022 U.S. Open champion, considered the world’s next great tennis star and the betting favorite in Flushing, was stunningly ousted Thursday night by unseeded Dutchman Botic van de Zandschulp. 

The third seed was overwhelmed by van de Zandschulp, who entered the match with a 12-18 singles record this year, who had a lifetime 5-13 record against top-10 players, who had advanced past the fourth round of a grand slam just once, when he reached the 2021 US Open quarterfinals.

The last two years, the 28-year-old van de Zandschulp failed to win more than two singles matches at any single grand slam.

Now, he’s into the third round in Queens after the biggest win of his career, and will meet No. 25 Jack Draper of Britain next.
