Modern men’s professional tennis does not really do small.

The last Grand Slam men’s singles champion who was not at least 183 cm tall was Gaston Gaudio of Argentina, the 2004 French Open champion. During the past decade, as tennis has become ever more physical, just two men under 183 cm have even made a Grand Slam final.

And yet, the most dangerous man in Paris right now besides Rafael Nadal and Novak Djokovic may be a steady baseliner from Argentina named Diego Schwartzman, whose listed height of 170 cm could be one of the more generous measurements in professional sports.
