Del Potro back with a win

Halep on form for Romania but France draw level in Fed Cup semi

Del Potro has been out of action for around 10-months after undergoing wrist surgery last year. 

He looked fit and sharp in beating 69th-ranked Stakhovsky. He now faces top seed Fabio Fognini in the second round.

The former US Open champion said after the match that he did still feel pain in his wrist, especially on the backhand side, but it did not hamper him on Tuesday.
