A question for Nadal fans. Obviously he's had a great year - his best since 2014, possibly 2013 (if he doesn't win anything else, his year will be similar to 2014, although in more playing time). But one worrying thing is that while he was great on clay, he's only been very good everywhere else. Compare:
CLAY: 24-1 (96%), 4 titles (including 1 Slam and two Masters)
HARD/GRASS: 25-8 (76%), no titles but a Slam final and Masters final
Now of course this is par for the course during his career, but on a cursory scan of his record, the main difference between his best years (2008, 2010, 2013, but really 2008-13), is that he upped his non-clay game to true elite levels, not just "very good."
So my question: Is this at all concerning to you? Is he now a clay specialist? Or do you think he'll be able to up his game and win another non-clay Slam, or at least a Masters or two?
