In Cincinnati 1983 you have Pat Cash losing to Leach in R64. ATP and ITF both have Cash winning this match and losing in the next round to Curren. https://www.itftennis.com/en/tournament/cincinnati/usa/1983/m-gp-usa-23a-1983/draws-and-results/,

In Geneva in 1983 (1983-322) you have John Brown (ID 109803) losing to Roberto Vizcaino in R16 (and winning R32). ATP has Jimmy Brown (ID 101131). https://www.atptour.com/en/scores/archive/geneva/322/1983/results

You have Velasco-jr (ID 102312) winning R128 at 1982 Roland Garros and losing to Vilas in R64. This can’t be right, because he was 8 yo. Obviously it was Velasco-sr (ID 109771). ATP agrees https://www.atptour.com/en/scores/archive/roland-garros/520/1982/results.

You have Jose Ayala (ID 101832) in the draw of Indianapolis in 1981 (tid 1981-419). This can’t be right, he was just 11 yo. It was another Jose Ayala. I don’t have DOB for him. ITF also think that older Ayala is from Chile (https://www.itftennis.com/en/tournament/uscc-indianapolis/usa/1981/m-gp-usa-22a-1981/draws-and-results/).

In 1982 Stuttgart Outdoor (1982-321) you have Jose Antonio Garcia (ID 102724) losing in R32 to Elter. But he was 6 yo. So another Gracia - Jose Garcia-Requena (ID 110788). See https://www.atptour.com/en/scores/archive/stuttgart/321/1982/results.

In Bristol 1981 (1981-313) you have Phil Dent beating Peter Kronk. While ATP has Paul Kronk (ID 100346) there: https://www.atptour.com/en/scores/archive/bristol/313/1981/results.
The same is for Cairo 1977 (1977-206). https://www.atptour.com/en/scores/archive/cairo/206/1977/results. In fact I’m not sure that Peter Kronk existed at all and not just mistaken spelling of Paul. In all places where I also previously had Peter mentioned, updated draws have Paul. I also had DOB for “Peter” and it was the same as for Paul. So initially I thought that they were twin brothers. But since neither main tour nor challenger circuit have any matches of Peter, I tend to think that this is a duplicate entry.

Conflicting info on players’ in Tokyo Outdoor in 1981. ATP has Takehiko Nishiwaki losing to Bob Weise. While the same draw in ITF version had Tokio Nishiwaki. Also ITF has DOB for him (now only showing an age). So I tend to stick with ITF version.

In the same tournament you have Takanobu Fujii losing in R64 to Dupasquier. This is also how ATP has it. But ITF has Wataru Fujii here. According to ITF Takanobu Fujii was born in 1987 and could not play in 1981.

In the same tournament you have Yasufumi Yamamoto losing to Fibak in R64. This is in disagreement with both ITF AND ATP. They both have Takao Yamamoto. Yasufumi Yamamoto was born in 1971 and being 10 yo could not play in 1981.

You also have Yasufumi Yamamoto in R64 in Tokyo Outdoor in 1979. ATP again has Takao Yamamoto there. https://www.atptour.com/en/scores/archive/tokyo/329/1979/results

In Sofia 1981 you have Bob Blazekovic beating Christophe Bernelle in R32. But ATP has Ismail El Shafei beting Bernelle and Blazekovic beating Stefan Svensson (ID 100803). So you have 1 match in R32 missing. https://www.atptour.com/en/scores/archive/sofia/364/1981/results.

In Auckland in 1979 you have Scott Clark (ID 108214) losing to Dale Collings. But Clark was 2 yo. So ATP fixed that and now have Australian Simon Clarke there. He is also in your players list – ID 202523.

Another case of discrepancy between ITF and ATP. You have LA 1979 draw according to ATP, where Tim Gullikson beat Alejandro Gattiker, while I have the same draw acc. to ITF (https://www.itftennis.com/en/tournament/los-angeles/usa/1979/m-gp-usa-36a-1979/draws-and-results/) where Carlos Gattiker lost to Tim Gullikson.

In Madrid in 1979 you (and ATP) have Pascal Portes beating Francisco Rodriguez from Paraguay (ID 102740). But this can’t be right, that Francisco Rodriguez was 3 yo. Another Francisco Rodriguez – from Spain was there. See ITF - https://www.itftennis.com/en/tournament/madrid/esp/1979/m-gp-esp-01a-1979/draws-and-results/ But he is not in your DB.

In Adelaide-2 in 1977 you have Scott Clark (ID 108214) losing to Tim Gullikson. But Clark was just born this year. So ATP fixed that and now has Australian Simon Clarke (ID 202523) there. https://www.atptour.com/en/scores/archive/adelaide/2013/1977/results. In the same tournament you have Phil Dent beating Tim Gullikson in R64. In ATP draw Dent beat Tom Gullikson, while Tim won the whole event.

Barcelona 1977 (tid 1977-425): you have R16 match Kodes-Bertolucci won by Bertolucci.
And then the winner losing to Eddie Dibbs. But both ATP (https://www.atptour.com/en/scores/archive/barcelona/425/1977/results) and ITF (https://www.itftennis.com/en/tournament/barcelona/esp/1977/m-gp-esp-03a-1977/draws-and-results/) have Kodes beating Bertolucci.

Conflicting info between ATP and ITF regarding 1977 November Johannesburg. ITF has, Sherwood Stewart beating local John Muller, while ATP has another Muller – Jorg from Germany. https://www.itftennis.com/en/tournament/south-african-open/rsa/1977/m-gp-rsa-02a-1977/draws-and-results/, https://www.atptour.com/en/scores/archive/johannesburg/426/1977/results. Your version corresponds to ATP.
But the problem with Jorg is that he was 11 yo. Going with ITF on this one.

In North Conway 1976 you have John Marks beating Terry Ryan. But ATP (https://www.atptour.com/en/scores/archive/north-conway/705/1976/results) and ITF (https://www.itftennis.com/en/tournament/north-conway/usa/1976/m-gp-usa-32a-1976/draws-and-results/) both have Anthony Ryan (ID 110139) as losing opponent.

In spring 1976 Madrid tournament (1976-309) there are 5 discrepancies. Both ATP and ITF have these results in agreement and they differ from yours:
Carlos Kirmayr beat John Andrews (ID 100263) rather than Andy Andrews in R32
Ricardo Cano beat Rafael Ruiz (ID 108036) rather than Manuel Ruiz in R64
Denis Naegelen beat John Bartlett (ID 100158) rather than Bill Bartlett in R32
John Lloyd beat Robin Drysdale (ID 100287) rather than Cliff Drysdale in R32

In Santiago 1976 (1976-361) you have Patricio Cornejo beating Hans Kary and then losing in QF to Kirmayr. But both ATP (https://www.atptour.com/en/scores/archive/santiago/361/1976/results) and ITF (https://www.itftennis.com/en/tournament/santiago/chi/1976/m-gp-chi-01a-1976/draws-and-results/) have Cornejo losing to Kary.

In 1976 Johannesburg (tid 1976-426) ITF and ATP agree that Cliff Richey beat John Muller (ID 107391) (https://www.atptour.com/en/players/johnny-muller/m354/overview) .

re: 1976 North Conway -- the only newspaper summary I could find, in the Boston Globe, says that Marks's first round opponent was Patrice Dominguez. The score matches what ATP and ITF have for Marks-Ryan. Hmmm. Dominguez seems unlikely, since he didn't play after getting injured at Roland Garros that year, and there are no other sightings of him in US newspapers in the second half of 1976. But ... what a weird mistake to make, if that's what it was.

Ian Hewitt is showing as having a loss to Manuel Orantes in Hamburg 1972 in SF (but with a different ID: 204615 vs 110091) . According to ATP it was Bob Hewitt (100040) who lost to Orantes. Also 3 wins of Bob in this tournament are wrongly contributed to Ian in TennisAbstract database.

Chris Lewis. Tennis Abstract contributes some matches of New Zealander Lewis (100474) to “British” Lewis (103993), who does not seem to exist, according to ATP/ITF. More precisely there is such player, but he is born in 1982 and couldn’t play in US Open 1984. All these matches (4 losses and 1 win) shall be contributed to New Zealander Lewis.

In Salisbury (1976-355) you have Pancho Gonzales losing to Gene Meyer. ATP has Adolfo Gonzalez there (https://www.atptour.com/en/scores/archive/salisbury/355/1976/results). ITF also does not have Pancho, they have A. Gonzalez, only listing him as American rather than Mexican. https://www.itftennis.com/en/tournament/u-s-national-indoor-champs/usa/1976/m-gp-usa-10a-1976/draws-and-results/

There is a discrepancy in Rome 1976 on who did Sherwood Stewart beat. ATP has Francisco Mastelli (ARG), while ITF has Mastelli, G. (URU). But since TennisArchives also has Francisco, I’ll consider this a prevailing version. Though may go to the list of ambiguous cases.

In Australian 1976 (1976-580) you have Geoff Brown (ID 109888) losing to Rosewall. But ATP (https://www.atptour.com/en/scores/archive/australian-open/580/1976/results) and ITF (https://www.itftennis.com/en/tournament/australian-open/aus/1976/m-sl-aus-01a-1976/draws-and-results/) have Greg Braun (ID 107132) there.

In Tehran 1976 both ATP (https://www.atptour.com/en/scores/archive/tehran/2011/1976/results) and ITF (https://www.itftennis.com/en/tournament/tehran/iri/1976/m-gp-iri-01a-1976/draws-and-results/) list Guillermo Vilas beating Frew McMillan (ID 100067). You have Kenneth McMillan.

Also U Unknown losing to Fibak is Patricio Rodriguez (CHI) – ID 100032.

In 1976 Barcelona-2 1976 (tid 1976-278) you have Eduardo Mandarino winning against Steven Turner in R64 and then losing to John Andrews. But both ITF (https://www.itftennis.com/en/tournament/barcelona/esp/1976/m-gp-esp-03a-1976/draws-and-results/) and ATP (https://www.atptour.com/en/scores/archive/barcelona/278/1976/results) have Jose Edison Mandarino. Eduardo was only 8 yo

Similarly in Madrid (1976-2015) you have Eduardo Mandarino losing to Taroczy. Should be Jose Edison Mandarino. https://www.atptour.com/en/scores/archive/madrid/2015/1976/results

In Sao Paulo 1976 (1976-240) you have Eduardo Mandarino again. Both ATP (https://www.atptour.com/en/scores/archive/sao-paulo/240/1976/results) and ITF (https://www.itftennis.com/en/tournament/sao-paulo/bra/1976/m-gp-bra-02a-1976/draws-and-results/) have Jose Edison.

The same is in Buenos Aires (1976-303). Losing to Julian Ganzabal is Jose Edison. https://www.atptour.com/en/scores/archive/buenos-aires/303/1976/results, https://www.itftennis.com/en/tournament/buenos-aires/arg/1976/m-gp-arg-01a-1976/draws-and-results/

In Sao Paulo WCT 1974 (1974-237) is the same mistake. Jose Edison won against Tom Leonard and lost to Borg. https://www.atptour.com/en/scores/archive/sao-paulo/237/1974/results.

Check also Kitzbuehel 74 & 73: https://www.atptour.com/en/tournaments/kitzbuhel/319/overview, https://www.atptour.com/en/tournaments/kitzbuhel/319/overview,
Madrid 73 (1973-309) - https://www.atptour.com/en/tournaments/madrid/309/overview
Barcelona WCT 71 (1971-425) - https://www.atptour.com/en/tournaments/barcelona/425/overview
Buenos Aires 68 (1968-303) - https://www.atptour.com/en/tournaments/buenos-aires/303/overview. There is Jose Edison in all those cases. Curiously in BA 68 you have Jose Edison winning R32 & R16 but Eduardo losing in QF. So you shall fix only QF here.

In Madrid 1975 (1975-2026) you (and ATP) have Georges Goven beating Stephen Taylor (IRL). But this Stephen Taylor could not play, because he was born in 1980 (https://www.atptour.com/en/players/stephen-taylor/t354/overview). So I have “Stephen Taylor-sr” there instead. Not in your DB.

“U Unknown” in your draw of Fort Worth WCT in 1975 losing to Stan Smith is Lee Merry (ID 202646). See https://www.atptour.com/en/scores/archive/little-rock/660/1977/results

“U Unknown” in your draw of Valencia n 1975 losing to Eric Deblicker, is Wanaro N'Godrella (ID 100193). Though ATP calls him “Waharo Godrella”, it is not hard to assume with a high probability who that is. See https://www.atptour.com/en/scores/archive/valencia/659/1975/results.

In Istanbul 1975 you (and ATP) have Mustafa Gencsoy losing R32 to Jun Kuki. The problem is that Mustafa was born in 1985 according to ATP themselves. I don’t remember where I imported my Istanbul results, but I have slightly different Mustafa there – Gengsoy. Could be just various spellings of the same name and they are father and son. In any case, the one born in 1985 could not play.

Wimbledon 75. You have Raul Ramirez beating Shozo Shiraishi , while all 3 sources (https://www.atptour.com/en/scores/archive/wimbledon/540/1975/results), (https://en.wikipedia.org/wiki/1975_Wimbledon_Championships_%E2%80%93_Men%27s_singles), (https://www.itftennis.com/en/tournament/wimbledon/gbr/1975/m-sl-gbr-01a-1975/draws-and-results/) have Nicola Spear (ID 100083) as a losing opponent.

In Bournemouth 1975 you have semifinal between Parun and Proisy reversed.

Brisbane 1972 (1972-326) It can't be Peter Carter losing to Dick Crealy, because he was 9 yo. ATP has David Carter (https://www.atptour.com/en/scores/archive/brisbane/9341/1972/results)

1972 US Open.
You have Mark Cox beating Jiri Granat,
Patricio Cornejo beating Donald Dell
Eugene Scott beating Robert Kreiss,

while both ATP (https://www.atptour.com/en/scores/archive/us-open/560/1972/results) and ITF (https://www.itftennis.com/en/tournament/us-open/usa/1972/m-sl-usa-01a-1972/draws-and-results/) have:
Mark Cox beating Mike Estep
Patricio Cornejo beating Dick Dell
Eugene Scott beating Mike Kreiss,
Also, this tournament is rare in a sense that it had R256 round as a part of main draw. There are 20 matches that you don't have included. ITF version has them.

In Hilversum 72 (tid 1972-317) Jan Hajek is an obvious typo (he was born in 1983), shall be Jan Hajer. Also ATP (https://www.atptour.com/en/scores/archive/hilversum/317/1972/results) has much more complete draw. They have 58 matches vs 39 in your database.

In Cincinnati 72 (1972-422) you have Jeff Simpson beating Jimmy Brown, while both ATP and ITF have William Brown. Jimmy was 7 yo.

In Boston 72 (1972-417) you have Unknown in R16 losing to Okker and another Unknown beating Ray Ruffels in R32, which creates impression that it could be the same Unknown. But looking at available sources: ATP (https://www.atptour.com/en/scores/archive/boston/417/1972/results) and TennisArchives (https://www.tennisarchives.com/edition/?v=19880) we can see that in R16 Okker beat Bob Carmichael, while you have Okker- Carmichael in R32. Before that Carmichael beat Ruffels in R32 and in R32 Okker beat Bob Maud.

In Wimbledon 72 you have John McDonald beating Jaime Pinto-Bravo and then losing in R64 to Tanner. But both ATP (https://www.atptour.com/en/scores/archive/wimbledon/540/1972/results) and ITF (https://www.itftennis.com/en/tournament/wimbledon/gbr/1972/m-sl-gbr-01a-1972/draws-and-results/) have Allan McDonald rather than John.

Omaha 72 (1972-2036). You have Gimeno passing Jimmy Brown, and the score says "DEF". ITF has only a final here. ATP (https://www.atptour.com/en/scores/archive/omaha/2036/1972/results) has William Brown as a losing opponent by walkover.

This concludes 1972

There is a bit of mix-up with Bohrnstedts in Merion 1970 (1970-2030). ATP (https://www.atptour.com/en/scores/archive/haverford/2030/1970/results) has Dick Crealy beating Dick R Bohrnstedt. So does ITF (https://www.itftennis.com/en/tournament/merion/usa/1970/m-gp-usa-14a-1970/draws-and-results/). But your draw as well as mine have Dave Bohrnstedt here as a losing opponent.
ATP has Sandy Mayer beating Ron Bohrnstedt, while ITF " Dick Bohrnstedt " again, which can't be right. TennisArchives version is the same as ATP.

In Hamburg 70 (1970-414) U Unknown, who beat Byron Bertram and lost to Pilic, is Adolf Kreinberg (id 112974). See https://www.atptour.com/en/scores/archive/hamburg/414/1970/results

J Bryant (RSA) vs John Bryant (USA). I’m not suggesting that those are the same player. But in 1970 edition of Nottingham you have J Bryant losing to Jaime Pinto Bravo, while I have John Bryant here. This tournament is in ATP archive only through QF and ITF does not have it. I took the data from TennisArchives (https://www.tennisarchives.com/edition/?v=17376) . What was your source of data for this tournament? If ATP then it looks odd that they removed earlier rounds.

From the same Nottingham tournament: you have J Jetson, losing to Ross Case in R32. In my source it was “Johan Jepson”. Given that my source has a full name rather than initial, I’m inclined to believe it more…

Also TA have Ross Case beating "L. Park" in R64, while you have Larry Parker (which looks more legit).

In Wimbledon 70 (1970-06-22) you have Nikki Spear beating Mohammad Hosein Akbari. Both ATP (https://www.atptour.com/en/scores/archive/wimbledon/540/1970/results) and ITF (https://www.itftennis.com/en/tournament/wimbledon/gbr/1970/m-sl-gbr-01a-1970/draws-and-results/) have another Akbari - Taghi.

There is a duplicate, I already mentioned - Norm/Norman Schellenger (ID 100716/ 202982). I was positive that this was a duplicate, because DOB was different exactly by one year 1961-01-12 vs 1962-01-12. But in my database I also have Norman D. Schellenger born in 1931 (probably the father). Younger Schellenger could not play in Charlotte 1970, since he was 8/9 yo. Therefore it has to be the father. ATP has only the name w/o DOB.

In Monte Carlo 70 (1970-410):

Buenos Aires 69 results (tid 1969-303) are much more complete on ATP site - https://www.atptour.com/en/scores/archive/buenos-aires/303/1969/results
Also in R32 Franulovic beat Jorge Kon rather than Alejandro Kon, who is born in 1986.
Although ATP has Fillol beating "Jorge Martinez" in R32, while ITF have this draw only through QF. TennisArchives (https://www.tennisarchives.com/edition/?v=7648) have Fillol beating Juan Carlos Martinez in R32. Also ATP and TA have Milan Holecek beating Carlos Ayala rather than Luis. And Julian Ganzabal beating William Alvarez rather than Lito.

In Cincinnati 1969 (tid 1969-422) U Unknown, who beat Michael Sprenglemeyer and lost to Charlie Pasarell in R64 is Juan Arredondo (id 117307). https://www.atptour.com/en/players/terry-bennett/b177/overview.
Another Unknown, who lost to Gorman in R128, is Carlos Medranos (id 204632). In TA draw he is spelled as Carlos Medrano. ATP draw also shows that Bob Carmichael beat the same Carlos Medranos, which can't be right.

In Washington 69 (1969-418) You (and ATP) have Luis Alberto Ayala beating Donald Dell in R64. Then ATP, being consistent have Luis Alberto Ayala losing to Koch in R32. You, on the other hand have Luis Ayala in R32. Probably R64 was imported from the other source than the rest of the draw. The problem with Luis Alberto is that he was 10 yo. Correct player is Luis Ayala (DOB 1932-09-18).

In Roland Garros 69 you have Vladimir Zednik beating Anton Ivanov (UZB). Not only the country of Uzbekistan did not exist yet, but also Anton was born in 1970.

In Auckland 69 (1969-301) you have Ray Moore beating Dan Cassidy. ATP (https://www.atptour.com/en/players/dan-cassidy/ch99/player-activity?year=all) does as well at the first glance. But looking at the results and the link - it is not the same Dan Cassidy that played since 1984 and later (that one has DOB in 1961). - https://www.atptour.com/en/players/dan-cassidy/c022/overview
The player that has id 100740 in your database can't be this guy. Actually TA (https://www.tennisarchives.com/player/?pl=18703) has the right guy - only he is Don Cassidy.

Also you have Loyo-Mayo beating Jeff Robbins, while both sources have Frank Robbins (id 100212)

In the Dublin 68 draw Louis Pretorius is obviously a mistake, taken from ATP draw. He was born in 1993. Correct player is Quentin Pretorius (id 202898), see https://www.tennisarchives.com/edition/?v=3831

In Roland Garros 68 you have Tom Christensen passing by Bungert by w/o and losing in R64 to Terry Ryan, while both ATP (https://www.atptour.com/en/scores/archive/roland-garros/520/1968/results) and ITF (https://www.itftennis.com/en/tournament/french-open/fra/1968/m-sl-fra-01a-1968/draws-and-results/) have local player Yves Christiaen instead.

U Unknown, who lost to Cliff Richey in R16, is Rafael Osuna
