Cape Town - Kevin Anderson was overwhelmed after reaching the semi-finals of the US Open on Wednesday.
The South African No 1 beat America's Sam Querrey 7-6 (7/5), 6-7 (9/11), 6-3, 7-6 (9/7) in their quarter-final clash to reach the last four of a Grand Slam for the first time.
“This is incredible,” Anderson said after his win.
“At this stage and playing on one of the most famous courts in the world... getting through, it feels absolutely fantastic.”
Anderson is also the first South African to make the semi-finals of the US Open in the Open era of tennis, which started in 1968.
Before that, Cliff Drysdale from South Africa had made the final of the 1965 US National Championships, as the US Open was then called.
The last South African to reach the semi-finals of a Grand Slam was Wayne Ferreira at the 2003 Australian Open.
In Friday's semi-finals, Anderson will take on 12th-seeded Pablo Carreno Busta of Spain. The winner of that match will reach his first Grand Slam final.
Carreno Busta advanced with a 6-4, 6-4, 6-2 victory over 29th seed Diego Schwartzman of Argentina.
