Rafa Nadal aims empty boxes with Serve in Practice

It was an intense training session for the visiting Spanish tennis team that turned into fun watching for a few fans gathered at the DLTA complex as Marc Lopez and Rafael Nadal aimed at empty ball boxes with their serves. David Ferrer and Feliciano Lopez were first to hit the courts in the morning session and once they were done with their routine practice -- the groundstrokes, the volleys and the serves -- in came Nadal and began his drill under scorching heat.
