Davín won his first ATP-tour match at 15 years, 1 month against Hans Gildemeister in Buenos Aires. He holds the Open Era record for being the youngest player to win a tour level main draw match. Davín won three singles tournaments on the ATP Tour, and reached a career-high singles ranking of World No. 30 in October 1990.
He coached fellow countryman Juan Martín del Potro until July 2015, and was the captain of the Argentine Davis Cup team. Under Davín's tutelage, Del Potro won the 2009 US Open, defeating Rafael Nadal in the semi-finals and Roger Federer in the final en route to the championship. Davín also coached Gastón Gaudio when he won the 2004 French Open and Grigor Dimitrov from 2015 to 2016.
Davín had an excellent junior career, reaching the US Open Boys' Singles final and winning the French Open Boys' Doubles (both in 1986).
Turning professional in 1987, Davín's best slam performance was reaching the quarterfinals of the 1991 French Open, where he defeated experienced clay-courter Martín Jaite as well as Christian Bergström, Marián Vajda and Arnaud Boetsch en route before losing to Michael Stich.
