I honestly see no reason why Vinciguerra isn't being chosen by Sweden to represent Davis Cup. He is a former world number 33 and in my eyes a top 50 - 75 player without question. He has only played 8 tournaments in the last 12 months, but he did qualify this week for Zagreb ATP and is a handy clay court player.
Yeah I don't understand it either. I thought they would be selecting guys like Vinci and Pim Pim for the second position and by the time they are done Daniel Berta will be coming through. Maybe they dont want to run the risk of injury. Other than that I'm not sure.
