Tearful Juan Martin del Potro loses comeback at Argentina Open
Juan Martin del Potro made a losing return to tennis after a two-and-a-half-year injury absence on Tuesday, beaten in straight sets by compatriot Federico Delbonis in the Argentina Open. In what was expected to be one of Del Potro's final appearances before retiring, the 33-year-old former US Open champion was overcome with emotion towards the end of Delbonis's 6-1, 6-3 victory in 1hr 23min. The former world number three wiped away tears as he prepared to serve what would turn out to be the final game of the match.
