Maintaining a 90% winning percentage - the Open Era greats

Thanks - I appreciate this quite a bit. Did you use the ATP site alone, or others - I found myself having to cross-reference between the ATP/ITF and a few other sites for the 70s guys, as record-keeping has never been a strong suit for tennis's governing bodies, sadly.

Thanks again.

Your most welcome - happy to play a small part in adding on tidbits to your exceptional and broad work

I used the ATP site exclusively for this - I agree with you that its impractical to look beyond what they deem 'official' for this exercise

I got the yearly records of players from Wikipedia (which I think uses the ATP site as the source) and along with my prior knowledge of the years and main players (which is sufficient to have a good idea who might have been close to hitting 90% and at what times) identified potential cases that meet the requirements

For example, I knew Wilander had a close to 90% record in 1983 - call it the base year

Then looked to either side of the year in question - and saw if there was a way of finding a 1 year period by slicing off early or late parts from the base year and replacing them with an equal time period from the appropriate adjacent year to take the win rate to 90%

Personally, I have issues with withdrawals... seems unfair to me to withhold status (for winner and loser both) when one guy isn't fit to play... I think it'd be a shame if a guy missed a spot on the list because a guy he was almost sure to beat withdrew

For Nastase though, I'd consider it ok as he withdrew first round of the tournament (Indianapolis 1972) without hitting a ball in the tournament, much less the match

Finally got around to updating this - Roger adds 4 more months to his tally (technically it is still going between Wimbledon 2016 and Miami 2018), bringing his cumulative time above 90 percent to an astounding almost 9 years.

Why did it take you so long?
This is more of a bump than an update.
 
Nice attempt, but suffers from one major problem. It doesn't take into account the level of opposition. You have to find a way to objectively rank the opposition. This is difficult to do, but it is the only way if you wish to provide an accurate picture. Please, don't be disheartened by my comment. It is a great job you have done, but, for conclusions to be drawn, opposition has to be taken into account.

Exactly. As someone mentioned earlier, you stick a journeyman like Ferrer in the mix of 4 top players and numbers skew greatly compared to a time were your top 4 were far and away above everyone else, and your top player still another level from the other three.

There's a great story about when Paul Westerberg of The Replacements finally met Prince when one sidled up to the other at a urinal in some Minneapolis nightclub. "What's up?" said Westerberg. "Life," replied Prince.

Anyway, life.
 
One more update: I took a quick gander at Nadal to double-check, and it turns out he indeed qualifies for another entry. From Monte Carlo 2017 to Barcelona 2018 (which is just slightly greater than 12 calendar months), at 64-7 he stayed above a 90 percent w/p. I have added this entry to the original post - one interesting effect is that he now leapfrogs both Borg and Djokovic in the cumulative rankings for both time and wins.
 
Interesting to note Lendl had 5 calendar years in the 80s with a 90+ winning percentage, yet 'only' won 8 slams in his entire career. That's far less slams than Federer (3 calendar years @90+), Sampras (??), Nadal (1)and Djokovic (2) won. It just shows what a competitive period the 80s was!

I never saw this thread before, so your update resurrected it. VERY interesting stuff...

Sampras' best season winning percentage was 87% in 1994 and his second best was 86% in 1997, his only two seasons above 84%. His last YE #1 season's (1998) win% was 78. He had better win% in 1992 and 1999 :rolleyes:
Fed has four 90+% seasons if you include 2017.

Yes, I only realised after I wrote it. The fact that Federer had a 90+ winning percentage in 2017 at 36 is very impressive to say the least, but I wouldn't rate it on the same level as his 2004-06 years. Besides the fact the field was nothing to rave about in 2017, Fed missed the clay part of it. Had he competed during the clay swing, just like in his younger days, I'm quite certain his % would have dropped to below 90.

That goes without saying. But the field was still pretty good during the AO-IW-Miami swing and Fed still dominated, so he didn't need a weak field entirely.

Yes, he did skip clay, but I would say dominating HC and grass at 35-36 still makes his winning percentage impressive, since it encompasses 2 surfaces.
 
If we had to replace Nadal with Lendl in 1980-92 and Lendl with Nadal in 2005-17, then I’m quite certain their slam tally would be reversed:

Lendl (16) > Nadal (8).

LoL Lendl made so many Slam finals and won just 8. Nadal so much better than Lendl in Slam finals. And he won most of his Slams against Federer and Djokovic.

Nadal >>> Lendl. Twice the number of Slams and more to come. Go cry about it.
 
One more to add - Mats Wilander was 79-8 @ 90.8%, late February 1983 - early March 1984 (first round loss at Brussels)

Per ATP site, starting with Davis Cup rubber on 28 February '83 vs Indonesia (2-0) through to Davis Cup rubber on 20 February '84 vs Ecuador (2-0).... he was 79-8

He fell under 90% mark with a first round loss at Brussels '84 which began 5 March - thus, just edging past the 1 year mark

That one is/was a hard judgment call I made (also Agassi August 1994-1995); I drew the line by tournament rather than by match, and only allowed a player to "bank" time between tournaments if he stayed at or above 90 percent by his last match at the latter tournament. This was done somewhat to address the Borg issue, who theoretically could have banked time between his last tournament before his 1981 sabbatical from ATP events through his first tournament in his 1991 comeback a decade later.

Under that logic, Wilander was just under rather than over 12 months b/w Feb. 1983-84. I'm open to counterarguments though, and appreciate you flagging how good Wilander was in 1983 (I recall there are some folks in the Former Pro forum who think he should share the PoY for 1983 with McEnroe).
 
Personally, I'd include Wilander - but can understand someone not doing so as per the argument above

I'm open to counterarguments though...

Lets have at it, then:cool:

When I hear "Maintaining 90% winning record for a year".... I think of "a year" as a tennis season cycle, more than the fixed number 365 days

Intuitively, I consider every 90% season to fulfill the criteria... but per the reasoning you've used, they aren't necessarily. If the guy loses first match of the next season and goes below 90%... than that wouldn't qualify.

This scenario seems to be missing the broader, real point of the exercise to me

Wilander's run started at Davis Cup first round 1983 and ended after Davis Cup first round 1984.... he completed a tennis cycle (the odd day here or there isn't all that important)

I drew the line by tournament rather than by match,

I like this move of yours.... because Wilander's was Davis Cup at both ends - as opposed to a normal tournament - it gets confounded a bit for his case.

Taking the Davis Cup to be a "tournament", Brussels - where he fell under - is 1 tournament beyond the seasonal cycle


That one is/was a hard judgment call I made (also Agassi August 1994-1995

Agassi is a bit different because he was under 90% going into the 95 US Open (88-10).... so he needed to win that event to take him past 90

Wilander was over 90

the Wilander equivalent for Agassi would have been his winning the 95 US Open to go over 90%, but be short of 365 days... and go under 90 in his next tournament when he's past 365 days. I would include him in that case

The Agassi equivalent for Wilander would have been had he lost a match at Davis Cup 1984, which would keep him below 90.... and of course, he wouldn't qualify

As it happened, my verdict would be Wilander in, Agassi not in

This was done somewhat to address the Borg issue, who theoretically could have banked time between his last tournament before his 1981 sabbatical from ATP events through his first tournament in his 1991 comeback a decade later.

If we were following rules like laws, Borg's 15+ year streak would fall under the heading of frivolous lawsuit:)

A small activity clause or minimum # of matches item can take care of him

Without one or the other, anything is possible.... Sampras would not just join the list, but remain on it for eternity with a 7-0 record

All in all, I think Wilander's run is cleaner than a few recent entries... like Federer's ongoing, missed 6 months through injury and clay-free run or Nadal's
injury 'abetted' streaks where he missed tournaments on surfaces less favourable to him

... appreciate you flagging how good Wilander was in 1983 (I recall there are some folks in the Former Pro forum who think he should share the PoY for 1983 with McEnroe).

We had a great thread on that that you might find interesting - https://tt.tennis-warehouse.com/ind...anking-of-mats-wilander-1983-and-1985.587893/


Gist is
Wilander was ranked 4th, behind Mac, Lendl and Connors

Win loss records for the year -

Wilander 82-11 @ 88%
McEnroe 63-11 @ 85%,
Lendl 75-16 @ 82%,
Connors 52-11 @ 83%

Big Tournament titles (Grand Slams and 250,000 or more prize money)

Wilander has 5 - Australian, Stockholm, Monte Carlo, Lisbon and Cincy
Connors has 3 - US, Memphis and Las Vegas
McEnroe 3 - Wimbledon, Philly, Wembley
Lendl 3 - Milan, Canada, Tokyo

Biggish tournament titles (200,000 prize money)

Wilander 2 - Guaraja, Barcelona
Connors 1 - Queens
McEnroe 1 - Sydney
Lendl 1 - San Francisco

@KG1965 worked out the ranking was due to a few Wilander early exits costing him heavily under the average per tournament ranking system used at the time

As for player of the Year, the ITF choice had always gone to the Wimbledon champion since its inception in 1978

The judges were Don Budge, Fred Perry and Lew Hoad

It sounds like their choices had all been unanimous until 1983 - when Hoad voted for Wilander

You know what: I'm sold. I think your core argument - that maintaining the percentage through the same event in back-to-back years qualifies - is a sound one; I'm persuaded entirely that it represents completing a single cycle through the calendar, plus one event. I've added Wilander into the list.

I hate to be repetitive but... untestable claims are not valid. That's like claming that unicorns exist in an alternative universe. The claim "unicorns exist in an alternative unvierse" cannot be refuted, and it doesn't mean that it's true. The same applies to your claim.
 
Post RG update: With Nadal's wins in Rome and Paris, he extends his time above 90 percent in both directions (now pulling in his finalist appearance at Miami 2017).

Jimmy Connors really stands out with the number of matches played in his streak - 640. The second longest streak, Federer's, includes 496 matches. That is a difference of roughly 2 seasons worth of matches by modern standards.

I think Pete and Andre's omission might inadvertently point to the pinnacle of surface specialization in the sport whereby they were both denied the wins necessary (to gain entry in this list) by some stern opposition which today's forum "experts" might call journeymen, mugs, clowns etc.

This thread must have taken a lot of time to compile. Bravo!
Glad someone understands this. Most such experts are engaging in the height of irony in so doing, given their favorite player.
 
Djokovic added another year and a half at the age of 36, from April 2022 until today!

From Belgrade22 until Paris23, 91wins and 10loses, winning rate 90.09%

I believe it would be even more if it were not for the pandemic and discrimination in AU and US

Not yet. He has to win ATP finals without losing 2 matches to maintain the 90%. Let's be modest right now.

Ok this is contiguous then makes sense.
 
So now that we've entered the postseason lull (congrats again to the one and only N. Djokovic), I thought I'd post early results of a little research project I've been working on here and there - I think it's in roughly decent enough shape to include here, and feels timely as the dust settles on where exactly the most recent greats stand relative to early Open Era stars (i.e. Djokovic v. Connors or Lendl; Nadal v. Borg or Sampras).

Here's the story: I wanted to try to measure both consistency and excellence across Open Era generations, so I decided to research the longest chronological stretches where a player who came of age during the Open Era maintained a 90% winning percentage. I used the following guidelines:

1. Sanctioned matches only (just a matter of stats currently being harder to compile for invitationals/challenge matches etc., not to mention issues regarding relative prestige/seriousness of different invitationals/exos etc.)
2. Contested matches only (thus, for instance, wins or losses via a mid-match default or injury retirement are included, while walkovers etc. are not - there must've been at least one ball in play).
3. To qualify for the list, the player must have maintained an overall 90% record for a period longer than 12 months.
4. Results are added by tournament rather than by match (thus, for instance, if a player peeks briefly above 90% for a 12+ month period partway through a tournament but loses later in the event and falls back below the dividing line, no credit is given).
5. Chronological measurements are prioritized when overlapping time periods are in play (i.e., if a player is at or above 90 percent either between, say February 2005 - May 2006 or April 2005 - June 2006, the former time period obtains).

Anyway, here goes - in the spirit of the project, I'm gonna go chronologically through to the present:
