It's nice to see Kuhn getting some really good results this year, could easily become another ATP-ranked player born in 2000 after Auger 2 weeks ago. He has now some wins over ATP ranked players on juniors level and hopefully he will make his ATP debut later this year.
I wonder how safe it is that he won't switch back to representing Spain at some point, his connections to Spain are quite strong and as a JCF-player he often gets wildcards there. But at the moment he is in the DTB "top talent team" with Zverev, Altmaier and Molleker. Molleker is the other bigger hope for Germany and has won back-to-back Grade 4s.
