Some countries only get one Grand Slam champion…
The United States, Australia, and Great Britain have produced at least 100 major titles each.
Adding to that, the likes of Spain, Serbia, and Switzerland all sit on 20+ Grand Slams, largely thanks to the success of Rafael Nadal, Novak Djokovic, and Roger Federer.
Who is the greatest male tennis player of all time?
There are, however, seven countries that have developed just one singles major winner in their history.
Those countries are Canada, Chile, Ecuador, Kazakhstan, Latvia, South Africa, and Mexico.
All seven players left a lasting impact on tennis, but perhaps none more so than Mexican legend, Rafael Osuna.
Rafael Osuna was the only Mexican player to win a Grand Slam
Osuna found success in another sport before switching to tennis, as he competed in the Mexican National Table Tennis Championships before he was 10.
Making the move to tennis, Osuna adjusted quickly and won the Wimbledon doubles title in 1960.
The Mexican continued to enjoy success in doubles, winning the US Open (US National Championships) in 1962 and Wimbledon again in 1963.
His greatest triumph, however, came in the singles, as he arrived in New York as the number-four seed in 1963.
Having lost in the semifinals two years running, Osuna was determined to go one step further in 1963, and he certainly delivered.

- 1963 US Open SF – Rafael Osuna defeated [1] Chuck McKinley, 6-4, 6-4, 10-8
Defeating the number-one seed in the semifinals, Osuna qualified for his maiden Grand Slam singles final.
Standing between Osuna and the US Open title was home favorite Frank Froehling, who had stunned Australian legend Roy Emerson in the fourth round.
Not willing to let the opportunity slip through his fingers, Osuna defeated Froehling in straight sets, 7-5, 6-4, 6-2, to become the first-ever Mexican Grand Slam champion.
He reached two further semifinals, but was unable to add to his Grand Slam tally.

| Grand Slam | 1960 | 1961 | 1962 | 1963 | 1964 | 1965 | 1966 | 1967 |

Osuna only won one Grand Slam, but left his mark in tennis and played a role in helping tennis return to the Olympic schedule.
How Rafael Osuna helped tennis return to the Olympics
After winning the US Open in 1963, Osuna’s popularity skyrocketed in Mexico.
He became so popular that event organisers were reportedly desperate for him to be involved at the 1968 Olympic Games in Mexico City.
Tennis had been absent from the Olympic Games since 1924, but returned in 1968 for a series of exhibition and demonstration events, in a bid to capitalise on Osuna’s success.
There were no medals on offer, but that didn’t bother Osuna, as he won three events in front of his adoring Mexican fans.
- Demonstration event – Men’s doubles
- Exhibition event – Men’s singles
- Exhibition event – Men’s doubles
Just 20 years later, tennis returned to the Olympic calendar as a medal event, with Miloslav Mecir and Steffi Graf winning gold in Seoul, South Korea.
Osuna wasn’t there to witness the event; however, as he tragically passed in an aviation disaster in 1969, aged 30.
He remains the greatest Mexican player to have ever played tennis, but can anyone carry on his legacy and add to the country’s Grand Slam tally?
Who is the best Mexican player on the ATP Tour?
The top-ranked Mexican player on tour is 20-year-old Rodrigo Pacheco Mendez.
Pacheco Mendez is currently ranked 228th in the world, but is heading in the right direction.
Receiving a wild card into the Mexican Open earlier this year, Pacheco Mendez stunned Aleksandar Vukic in the first round, to pick up the biggest win of his career.
He then qualified for his maiden ATP quarterfinal when Norway’s Casper Ruud withdrew from the tournament.
The win catapulted him into the world’s top 250, and he has remained there ever since.
Whether he can make another step forward in 2026 remains to be seen, but it will definitely be worth looking out for.
