24. Yevgeny Kafelnikov- When you look at the former world No. 1's stats, nothing really jumps out at you, but the Russian did a little bit of it all. He was atop the rankings for six weeks, won two majors, knocked out 46 top 10 opponents, won 26 titles, and was victorious in 609 matches.
22. Michael Chang- The former world No. 2 won his only grand slam title when he was only 17. Even though he never won another major, he did collect 34 titles and 51 wins against top 10 opponents.
21. John Newcombe- At 30-years old, the Australian finally reached world No. 1. Newcombe won five majors in the open era and won 31 tournaments.
20. Thomas Muster- If these were clay court rankings, he would be top 10, but he spent six weeks as the top ranked player in the world and won 44 titles.
19. Arthur Ashe- The player whose name is on the center court at the US Open is best known as a humanitarian, but the former world No. 2 won three grand slam titles and 623 matches in his career.
18. Rod Laver- Laver is the one of the greatest tennis players in all of tennis history, but the bulk of his career came before the Open Era, and since computer rankings didn't begin until 1973, he was never ranked higher than three in the world. However, Laver still won five majors and 42 titles in the Open Era, including the last calendar slam in tennis.
17. Jim Courier- The American spent over a year as the best player in the world, winning four grand in three years. Courier is one of the only Americans to have success on both clay and hard courts. Although most fans would rank Courier between 10 to 15, his inability to dominate lower ranked opponents hurt his ability to rack up titles. Courier won only 23 titles and lost 164 matches to players outside the top 10.
16. Ilie Năstase- The Romanian was the first person ever ranked No. 1 according to the computers. The two-time grand slam champion is another player who would have been higher on the list if his whole career was in the Open Era. He still won 750 matches and 56 titles, dominating the ATP World Tour when it first began.
15. Guillermo Vilas- The Argentine was the third winningest player of all time notching an incredible 923 match wins as well as 63 titles, including four grand slams. However, that is where the former world No. 2's list of accomplishments ends. Aside from failing to reach world No. 1, he only had 29 wins over top 10 opponents. Vilas is widely considered the best No. 2 player in tennis history, but failing to reach world No. 1 knocked him several spots down on this list.
14. Andy Murray- The Brit is still moving slowly up this list. He is now a three-time grand slam champion and he ranks ninth in tennis history in wins against top-10 opponents. He is the highest ranked player on this list to never be No. 1. By the time his career is over, he could easily be inside the top 10 of this list, especially if he reaches No. 1 at some point.
13. Lleyton Hewitt- As a young Australian, Hewitt spent 80 weeks as the top-ranked player in the world, but failed to live up to his potential, winning just two majors and 28 total tournaments, while suffering countless injuries. Aside from being the best player in the game for 80 weeks, his top accomplishment was his 65 match wins over top 10 foes. Although Hewitt is still competing, he is far from the player he was just over a decade ago.
12. Mats Wilander- The Swede made his way this high on the list for one reason and one reason only. The guy knew how to win majors. Seven of his 33 titles were at the slams. That is the third best ratio of any player on this list. His win percentage was 7.5% higher in majors. Wilander only spent 20 weeks as the world No. 1 and only won 571 matches. Those numbers are good, but they are way below average for a top 15 player on this list. Wilander consistently rose to the occasion when it mattered most at the majors, winning seven grand slams in the span of seven years.
11. Boris Becker- If 713 wins wasn't enough for the six-time grand slam winner to crack the top 10 on all GOAT lists, then maybe I should remind you that 121 of his wins were against top 10 ranked opponents. That is the third most in tennis history. Becker also won 49 titles and was the world No. 1 for 12 weeks. Becker was a model for consistency, winning at least two tournaments every year for 12 consecutive years. At just 18 years of age in 1986, Becker reached nine tournament finals and won Wimbledon for the second consecutive year. Becker went on to win one more Wimbledon, the US Open, and the Australian Open twice.
10. Stefan Edberg- When it comes to Edberg the numbers speak for themselves. 72 weeks as world No. 1, six grand slam titles, 41 tournaments won, and 801 match wins. However, what may be most impressive was the way he handled the other legends of his era. Edberg totalled 47 combined wins against Becker, Lendl, Chang, and Wilander. Edberg's biggest weakness was his clay court game, but he made up for it with two major titles at each of the non-clay slams.
9. Andre Agassi- The American may not be the statistical leader in any category, but he was one of the most well rounded players to ever play. Agassi dominated on every surface and is one of only two male singles tennis players to achieve the career golden slam. Agassi finished his career with eight grand slam titles and 60 tournaments won over the span of 19 years. The former world No. 1 won 870 matches and spent over 100 weeks atop the rankings.
8. Björn Borg- A lot of fans would put Borg in the top five, but he is getting any bonus points from me for quitting when he was just 25. However, his dominance in just eight years on the world tour is still enough to place eighth on this list. In that short span, he won an incredible 64 tournaments, including 11 majors. Borg also spent 109 weeks as world No. 1 and won over 70% of his matches against top 10 opponents. Even more impressive than that is his 89.8% win rate at the slams. His numbers are astonishing, but we can only wonder how good he could have been if he continued playing for another eight years.
7. John McEnroe- Known more for his tirades than actually playing tennis, McEnroe truly is one of the greatest players in tennis history. The five-time Wimbledon finalist ranks fifth in the Open Era in weeks at No. 1, titles, and wins. In 1984, the American won 13 titles and only lost three matches in the entire year. McEnroe finished his career with 77 titles, which ranks third in the Open Era. Along with seven grand slam titles, he spent 170 weeks as the World No. 1. McEnroe finished his career with 875 match wins. Where McEnroe made his mark in tennis was in Davis Cup ties. McEnroe led the United States to five Davis Cup titles. McEnroe also won eight year-end Championships. Five at the WCT Finals and three at the Masters.
6. Rafael Nadal- Now that Nadal is tied for the second most grand slam titles on the all-time list, the debate for the greatest of all time is usually centered around him and Federer. Nadal also ranks third all-time in wins against top 10 opponents, which is one of the main stats that I look at when creating this list. However, Djokovic has now bumped Nadal out of the top five. While Nadal does have as many grand slam titles as Sampras and more than both Connors. Lendl and Djokovic, almost two-thirds of his major titles have come from the same event. As a result, Nadal has only accumulated 141 weeks as the world No. 1, which is barely half of what Connors and Lendl each have. Nadal is now 29, so he will continue to rack up titles and match wins and could eventually crack the top four, but he isn't there yet.
5. Jimmy Connors- The American is the winningest player of all time with 1243 match wins and 109 titles. When the first set of computer rankings came out, Connors was listed as No. 10 in the world. At 38 years of age in 1989, Connors was still ranked in the top 10 in the world. It wasn't until 1996 that Connors finally left the top 500 for good at the age of 45. However, the Americans only accomplishments weren't just the length of his career. Connors won over 80% of his matches, eight majors, and spent 268 weeks as the No. 1 in the world. Connors dominance is often overlooked, because it was stretched over a span of 20 years, but looking at the whole body of work, Connors is clearly among the four greatest tennis players in the Open Era.
4. Ivan Lendl- In my opinion, the most underrated player of all time, Lendl was the greatest player in the Open Era when he retired in 1994. When you look at the GOAT lists of other tennis fans, some list him as eight or nine or don't include Lendl in the top 10. That is nuts when you see that Lendl is in the top five for the Open Era in major titles, weeks at No. 1, titles, wins, and win percentage. Most fans rank him so low, because he lost 11 grand slam finals. However, I think that reaching 19 grand slam finals is yet another reason to rank him in the top four on GOAT lists. Lendl won eight grand slam titles and was the No. 1 player in the world for an incredible 270 weeks. Lendl also won 94 titles and 1071 matches, while maintaining a .818 win percentage.
3. Novak Djokovic- Djokovic has made incredible strides in the last five years, turning himself from a one-slam wonder to one of the greatest players the game has ever seen. Djokovic compiled the greatest season ever in 2015 and in 2016 he became the first player since Rod Laver to win the Grand Slam. Djokovic is only 29 years old and his prime years could last a little longer. Catching up to Sampras is certainly within reach if he is still the No. 1 player in the world this time next year. Then maybe we can start to talk about Djokovic chasing the greatest player of all time, but that is still a long way away.
2. Pete Sampras- The American is considered in the top 3 on almost every GOAT list in tennis and rightfully so. Sampras absolutely dominated the grand slams from the 1993 Wimbledon to the 2002 US Open winning 14 of the 41 majors, including a stretch of seven Wimbledon titles in eight years. Sampras knew all about playing his best when it mattered most at the slams. Sampras's win percentage in slams was 9.0% higher than in the rest of his matches. Sampras also had a stranglehold on the title of No. 1 player in the world in his career, holding the top ranking for 286 weeks. Sampras ranks second all time in wins over top 10 opponents with 124 and has 64 titles to his name.
1. Roger Federer- This is case closed by now. Federer is the leader in majors won, weeks at No.1, wins against top 10 opponents, and he is still going. Federer's records at the slams shatter those of any other player in the Open Era. Federer has spent 302 weeks as the world No. 1. Federer was the tyrant of the ATP rankings from early 2004 to the summer of 2008. From 2004 to 2006, he lost a total of just 15 matches. Federer has won 17 grand slam titles. The Swiss has reached the final of each grand slam tournament at least five times, and at one point, reached 10 consecutive finals. Some argue that Federer played in a week era from 2004 to 2008, but any era would look weak when one player dominates it so thoroughly. If you look at how Federer performed against the players who were ranked No. 1 in the world before him, you can see that he dominated even against the best opponents. Federer had a .760 win percentage against Agassi, Hewitt, Ferrero, and Roddick combined. Federer dominated the sport more so than any other player and did so for a longer amount of time than any other player. Therefore, he is the GOAT.
