128036 Rafaelnadal           Discovered 2003 May 28 at the Observatorio Astronomico de Mallorca.
Mallorca-born Rafael Nadal (b. 1986) was introduced at a very young age to tennis by his parents, and he played his first championship tournament in Baleares at age 8. He turned professional in 2001 and won his first men's Association of Tennis Professionals match. In 2006 he became player No. 2 in the ATP world ranking.
