Del Potro poised for comeback at Delray Beach Open

Cape Town - Juan Martin del Potro has been named as the top seed at the Delray Beach Open as he prepares to make his long-awaited return from injury.

The former US Open winner was forced to call a premature end to his 2018 season after fracturing his right kneecap at the Shanghai Masters in early October.

After initially pencilling in the Australian Open as his comeback tournament, he withdrew on the eve of the opening Grand Slam of the year.

However, he has been confirmed as a wildcard entry for this week's Delray Beach Open in Florida.

The Argentine will be the top seed and he will take on Yoshihito Nishioka of Japan in his first-round encounter.

Americans John Isner, Frances Tiafoe and Steve Johnson are also in the draw along with Australian Nick Kyrgios and Ivo Karlovic of Croatia.
