Kevin Anderson has admitted that he learned a "tough lesson" in a straight-sets loss to Stanislas Wawrinka in their US Open quarter-final.
Wawrinka kept his campaign alive in New York with a 6-4 6-4 6-0 victory, and despite losing in emphatic fashion in the last-eight clash, Anderson insists that he will take the positives from reaching his first Grand Slam quarter-final.
"It's a very tough lesson for me today and, you know, it's difficult not to think about it, but obviously I have got to take what I can. This week has been a great week for me, the last two weeks. There is a lot of positives," the South African told reporters.
"I always try to look at that to obviously keep motivated and keep improving."
