“Juan Martín Del Potro trained with Orsanic and Monfils.”

The pair was a successful combination in Cup play in 2016, with Argentina getting its first victory in the team competition. Del Potro has not played in a tournament since then.

He has not had a full-time coach since returning to the tour from wrist surgery in 2016, but worked with Dani Vallverdu at Wimbledon.

The 2009 U.S. Open champion has been practicing in Florida, where he trained with Gael Monfils.
