BASEL, Switzerland (Reuters) - Juan Martin del Potro's quest for an unlikely spot in the ATP World Tour Finals gathered pace as he beat Portugal's Joao Sousa in his opening match at the Swiss Indoors on Wednesday.

The Argentine, twice a champion in Basel, maintained the form he showed last week in capturing his first title of the year in Stockholm by overpowering Sousa 6-1 4-6 6-1.
