Anderson beat Querrey 7-6, 6-7, 6-3, 7-6 to become the first South African since Wayne Ferreira to advance to the last four.

Anderson says he is going to enjoy reaching his first Grand Slam semi-final, before focusing on his next match.

“I’ve put in a lot of work, so it feels good reaching a milestone that I haven’t before.

“At the same time I feel like I came into this taking it each match at a time.

“I think I’ll let myself enjoy this for the next day or so, take a couple of days off now and I’ll definitely refocus for my next match.”

Before Anderson’s quarter-final, the bookies tipped him as the overwhelming underdog, however, their tune has changed somewhat.

Anderson is now installed as the favourite to beat Pablo Carreno Busta, with odds of 1/3 while the 12th seeded Spaniard is the underdog at 41/20.

Carreno Busta in his turn beat Argentina's Diego Schwartzman in straight sets with a 6-4, 6-4, 6-2 win.
