Anton and Paul should really be stepping up to challenger level, under ranked and too good at 25k.
Anton played a challenger a few weeks ago, still just outside the ranking required to guarantee entry. Anton seems to play in 2 week blocks aswell, not sure if that's to balance his studies and other interests. I don't want to say he isn't 100% committed to tennis as he is clearly driven but he has said he has other interests. I think at 20 that's fair enough.
