I spent a week in the old pros section and come back here to see "Zed ahead of Fed"?
Did I just pop into an alternate reality?
What I see is a very good young guy who is unusual successful early on because his reasonably dangerous serve is mostly because of his height.
Don't get me wrong - the kid has lots of promise, if he stays healthy, but I'm exactly confident that we are looking at a 19 slam winner...
Just the facts in that thread and Zed is ahead of Fed in his progress with his 2nd tournament win at age 19.
Zed was dead tired today (well maybe not that much), but the stats engine is looking strong. I don't think he's been really playing all that well in most of his matches and had a lot of three setters last week (everything but the final.) Here is the stats engine:
1. Zverev won 39.6% of his return points on hard courts starting with US Open in 2016 with notably strong first return numbers
2. Now in 2017 he's jumped from 63.9% on serve points to 65.3%.
3. Games won percent on serve is even more impressive surging from 81% in 2016 to 86% in 2017
4. Zverev is up 2.0% on points won for the early part of 2017 versus the same period in 2016. 49.7% up to 51.7% now.
Zverev was around over 53% points won last Fall until he slumped a bit; he could easily get back to that kind of performance. I expect that clay and grass will be Zverev's best surfaces, so all told he's on ATG track.
I'm not saying Zverev will end up his career with more slams then Fed, but I expect him to pull ahead of Federer's progress for a 3 year window.
