Botic van de Zandschulp has spent the majority of his career playing tennis on the ATP Challenger Tour, which is a level just below the ATP Tour and has rarely cracked the top 100.
He has competed in 39 Challenger events since going pro in 2015, winning one of them in Hamburg in 2019.
Only two ATP Tour appearances in the main draw are being compared to this, both in 2021 at the Great Ocean Road Open in Melbourne and as a wildcard in Rotterdam.
Van de Zandschulp had previously participated in qualification for the Australian Open and Roland Garros in 2020, but has not yet played in a main draw Slam tournament.
The Dutchman, though, has made it into the main draw of every Slam this year after advancing from qualifying each time, including as a lucky loser for Wimbledon.
He has won seven straight matches, including a comeback victory in the first round by two sets to love and a five-set victory over 11th seed Diego Schwartzman, to get to the US Open quarterfinals.
Botic van de Zandschulp is expected to firmly establish himself in the top 100 for the first time in his career as a result of his US Open performance.
Currently, should he pull off a massive upset against world number two Daniil Medvedev, the Dutchman will jump from his current career-high ranking of 117 up to world number 62.
Van de Zandschulp is doing a good job of repping the Netherlands by making it to the final eight in New York.
He is the first Dutchman to advance to a Grand Slam quarterfinal since Sjeng Schalken did so at Wimbledon in 2004, which was more than 15 years ago.
