Differences in styles in different parts of the world

        I have always wondered why most south American play with the same styles while most North American have a totally different type of game. As a South American player studying in the US, I realized how different the way of teaching tennis was between both continents. This would explain why there are so many similarities between players of the same continent and so many differences with players from another continent.

John Isner (USA) VS Diego Schwartzman (Argentina)

First of all, a general tendency for North American is the following:

• Short point
• Flat and aggressive balls
• More points finished at the net
• More 'Serve and Volley' Type of game
• Players close to the baseline
• Main surface: Hard Court

And in South America, the trend is:

• Long rallies
• More spin in the ball
• Rarely go at the net
• Players far from the baseline
• Main surface: Clay Court

In Europe, the types of games vary a lot from one country to another. For example, Spain shares a lot of common points with South America, while France is more focused on the "technique" part of the game, and England shares some common points with the US.

Those differences in styles can be explained by the availability of tennis surfaces. For example, if a country has more clay courts than hard courts, the coaches and players will adapt their games, and take example on South America. 

Then, each country has a federation of tennis where most of the coaches are trained. In other words, most of the coaches of one country will learn the same techniques since they share the same federation and will transmit those techniques to their players. Most likely, the players of one country will have the same type of playing because of that. 

It doesn't mean that one country has a better way of coaching than another; it just means that they have different styles. Indeed, the current top #3 is Djokovic, Nadal, and Zverev which are all from different countries and have different types/styles of games. 

In a nutshell, tennis is a sport with a lot of variety, which allows the public to watch very different matches. This variety helps the sport to be entertaining as well.
