Carlos Alcaraz has earned a place in US Open history…

The 18-year-old Spanish player beat 141st-ranked qualifier Peter Gojowczyk of Germany 5-7, 6-1, 5-7, 6-2, 6-0 to reach the final eight at Flushing Meadows.

In the process, Alcaraz has become the youngest man to reach the quarterfinals of the US Open since 1963.

Alcaraz will now face No. 12 seed Felix Auger-Aliassime, a 21-year-old from Canada who reached his second straight major quarterfinal by defeating Frances Tiafoe 4-6, 6-2, 7-6 (6), 6-4 with the help of 24 aces.

“At some point, age is just a number,” Auger-Aliassime when asked about Alcaraz. “He already feels like a player that is established.”

The 55th-ranked Alcaraz got past No. 3 Stefanos Tsitsipas in his previous match and is the youngest player with two five-set Grand Slam wins in a row since Michael Chang was 16 at the 1988 U.S. Open.

Auger-Aliassime had never reached the final eight at any Grand Slam tournament until Wimbledon in July, a month before he turned 21 on August 8. Now the Canadian is the youngest man to reach consecutive major quarterfinals since Juan Martin del Potro made it to three straight in 2008-09.
