Kevin Anderson said he hoped he was not judged harshly on his maiden major quarter-final appearance, after being outplayed by Stan Wawrinka at the US Open.
Anderson finally broke into the last eight at a grand slam with a four-set victory over 2012 champion Andy Murray, but he failed to consolidate on it as Wawrinka coasted to a 6-4 6-4 6-0 win on Louis Armstrong Stadium.
Anderson had lost in the fourth round of a major seven times before finally experiencing round-of-16 joy.
On Wednesday, the big-serving South African produced 12 aces, but also nine double faults and only got one sight of a break point as the Swiss handled his less-experienced opponent with consummate ease.
Anderson said he wanted to use the experience to build on his ground-breaking run.
“It’s not that easy to do right now obviously just because of just the way I felt out there. It just really wasn’t my day,” Anderson told a news conference, when asked about taking the positives from the tournament.
“But it’s the thinking that I’ve just got to take those feelings that I have had, the way I have played throughout the last few weeks, especially in my round-of-16 to beat Andy there, and used it as extra motivation to give myself another chance.
“I definitely know I can do better than I did today.”
Anderson said he only felt in the contest for a short period, with Wawrinka wrapping up the rain-delayed match in one hour and 47 minutes.
“I thought conditions were quite quick and quite live, especially compared to my last match out there. One poor serve game in the first set and I wasn’t really making too many inroads on his serve,” Anderson added.
“I thought I sort of got it back a little bit in the start of the second set. Another poor serve game, and then things sort of went downhill a little bit.
“After… changing my clothes and having that bathroom break, I was just trying to compose myself and reset myself. I didn’t feel that out of sorts, but going back, it sort of snowballed a little bit.
“He started free flying, swinging, and I was trying to find my way a little bit. Obviously it was not a good one to be in.”
