not sure he's up there with Hewitt yet, but the rest I largely agree with. Let's not forget how good Hewitt was for a minute. Didn't he straight set Sampras at a US Open final? I applaud Sasha, he's taken advantage of a strange year. I'll remind you he's not beaten Sincaraz once this year. Hewitt was going out and rag dolling Sampras, and doing number 1 things for a while. There's no world in which Zverev has reached that type of level yet. Respectfully
I definitely agree that Hewitt had a higher peak. But it depends upon what sort of spans of time to consider, and as with all such conversations, how we choose to balance peak vs career, and also how we weigh "eyeball memory" vs. statistics.
I agree with you that during Hewitt's peak--especially 2001-02--he was a more dominant force on tour. Despite it being a weak period between peak Sampras and the rise of Federer, Hewitt
was the best player on tour for a period of time, which is something that Zverev can never claim. Even if he finishes #1 this year, he is clearly a distant third behind Sincaraz. I think whether or not one is the best player on tour at any point in their career is a significant factor in greatness.
Zverev has a longer and, overall, more robust prime. So far he's won big titles over a span of 10 years (hard to believe), from 2017-26. For Hewitt it was just a measly three years (2001-03).
Anyhow, here are their stats:
ZVEREV:
Slams: 2 Wins, 4/7/6 F-SF-QF
Other titles: 2 Tour Finals, 1 Olympics,
Rankings: Best #2; 6 years in top 5, 9 years in top 10
W%: 71%; best 80% (2021, 2026)
HEWITT:
Slams: 2 Wins, 2/4/7 F-SF-QF
Other Titles: 2 Tour Finals, 2 Masters, 2 500s, 22 250s
Rankings: Best #1 (two YE 1), 4 years in top 5, 5 years in top 10
W%: 70%; best: 82% (2001)
