Martín Miguel Vassallo Argüello is a retired professional male tennis player from Argentina. His career-high ATP singles ranking is World No. 47, achieved in April 2009 shortly after reaching the semifinals of Acapulco.

The 2006 French Open was a tennis tournament that took place on the outdoor clay courts at the Stade Roland Garros in Paris, France from 28 May to 11 June 2006. It was the 110th staging of the French Open, and the second of the four Grand Slam tennis events of 2006. This edition made history as it became the first Grand Slam tournament to start on a Sunday. It was the 2nd time since 1985 that all top 4 seeds reached the semifinals in the men's singles of a Grand Slam tournament. This did not happen again until the same tournament five years later. Both defending champions, Rafael Nadal and Justine Henin-Hardenne, retained their titles.
