Diego Nicolás Cristin (born 5 April 1981) is a former professional tennis player from Argentina.
A right-handed player, Cristin comes from the Núñez neighbourhood of Buenos Aires.[1]
Cristin was known for his fast serve, once registering 214 km/h while still a teenager, surpassing the fastest serve of any other Argentine player at that time.[1]
In 2003 he had the distinction of being the first player to beat future US Open winner Juan Martín del Potro in a professional match, which he did at a local satellite tournament.[2]
He was unable to break into the ATP Tour, featuring only as high as Challenger level. As a doubles player he made the world's top 200 and won a Challenger tournament in Santiago in 2009, partnering Eduardo Schwank.[3]
