Hugo Dellien Brings Tour-Level Experience
Hugo Dellien gives Porto its biggest name. The Bolivian has spent significant time on the ATP Tour and reached a career-high ranking of No. 64, while also winning 16 Challenger titles.
While much of his success has come on clay, Dellien’s presence gives this Challenger 75 field an established veteran to watch on the Portuguese hard courts.
NextGen Talent Gets a Challenger Opportunity
Porto also offers an opportunity for some of the tour’s younger players. Niels McDonald, currently No. 10 in the NextGen race, joins the field along with Mika Petković, while Gilles Arnaud Bailly and Max Hans Rehberg add more young talent to the draw.
