Anton Karlsson, who has won a competition on the second European Tour Challenge Challenge, is three strokes after leading Mikael Lindberg in the Katrineholm Open, which is part of the Swedish professional tour.

But it probably won't be for the overall result that Karlsson remembers this competition, but for his unlikely hole in one.

- It's totally sick. Probability is probably non-existent. The funny thing is that I've done HIO twice in three attempts at that particular hole. The last time I did HIO at Katrineholm it was a Challenge Tour competition and then I did it on the last lap. It was exactly the same flag placement then as today, he tells svenskgolf.se.

Karlsson has made a total of four holes in one at the competition and half of them have been at Katrineholm GK's hole 16.
