Sebastian Korda is taking plenty of positives away from the Australian Open, despite retiring hurt in his quarter-final against Karen Khachanov.

The American sustained an issue to his right wrist early in the second set, before calling an end to proceedings in the third when trailing 7-6 (7-5) 6-3 3-0.

Speaking at a press conference after his elimination, Korda said it was an issue he originally felt at the Adelaide International 1, where he was beaten by Novak Djokovic in the final.

"I had it a little bit in Adelaide a couple of weeks ago, but then it went away," he said. "During the matches, it was completely fine. Then just one kind of mishit return and it started to bother me a lot of after that.

"I knew what it was right away, right when I hit the return. I kind of felt that spot that I was feeling before. Some forehands I couldn't even hold the racquet. Volleying was almost impossible for me. So it was a little tough."

The number 29 seed was pleased with his work in Melbourne though, adding: "Obviously a lot of positives [to take]. Still a great tournament. My first quarter-final in a grand slam. I'm going to go forward with my head high and keep working."

Khachanov is through to his second-consecutive grand slam semi-final, having also made the final four at last year's US Open.

The Russian – who will face either Stefanos Tsitsipas or Jiri Lehecka next – sympathised with Korda but said he was just focused on getting the job done.

"It's part of the sport," Khachanov said. "It was a tough competitive battle until a certain moment, but at the end of the day you don't know how serious he's injured, right?

"I think the end of the second set, you know, when I pushed through and then took it with 2-0 lead by sets, it's extra pressure to the guy, if especially he has some issues physically.

"I think also the beginning of the third, you know, when you take this [3-0] lead, so from the opponent, the attitude change, it's way tougher to come back, so I think all those things together. I was quite focused and I knew what I had to do, how I had to push. I did it really well."
