Juan Martin del Potro is the latest tennis player to confirm his presence at next month’s Estoril Open.

The Argentinian, who is on the way back from injury having risen as high as No5 in the world in 2010, will take on the likes of Robin Soderling, Fernando Verdasco and Milos Raonic.

The Algarve’s Rui Machado, a first round loser in Morocco last week, will also take his place in the main draw alongside Davis Cup team mate Frederico Gil while defending champion Albert Montanes will not play this year.

Tickets are already available via, or by phoning 707 780 000.
