Unusual, ATP – Halle> And the ball became invisible …

Sebastian Korda was opposed to Kei Nishikori in the round of 16 of the tournament in Halle. He ended up winning in three sets (2–6, 6–3, 7–5). In the first set, the young American complained about not seeing the ball. In view of the images, difficult to prove him wrong. Already on grass, the color contrast between the ball and the grass is very slight, in Halle, the mixture of shade and sun makes visibility even more complicated.
