Team nominations out today: http://www.daviscup.com/en/news/256653.aspx
World Group:
Australia hosting USA
Australia: Nick Kyrgios, Jordan Thompson, Sam Groth, John Peers
USA: Jack Sock, John Isner, Sam Querrey, Steve Johnson
Kyrgios is motivated and playing well recently, both in doubles and singles. Still, big server Isner has a puncher's chance to beat him in singles, and a Sock-Isner or Sock-Johnson team could take the doubles rubber too (likely against Kyrgios-Peers). Sock should win his non-Kyrgios singles match.
Prediction: USA wins nailbiter 3-2
Belgium hosting Italy
Belgium: David Goffin, Steve Darcis, Ruben Bemelmans, Joris De Loore
Italy: Paolo Lorenzi, Fabio Fognini, Andreas Seppi, Simone Bolelli
Belgium is rightly favored to win, as Goffin is the best player there by a decent margin. But he still needs support from the rest of his team to get over the finish line. And the Italian team does play well when wearing the azzurro.
Prediction: Italy pulls off the upset, 3-2 (losing both Goffin singles rubbers)
France hosting GB:
France: Lucas Pouille, Gilles Simon, Nicolas Mahut, Pierre Hugues-Herbert
GB: Dan Evans, Kyle Edmund, Jamie Murray, Dominic Inglot
Should be little doubt about who is playing singles/doubles for each team here. Strength against strength in doubles could go either way, but France's singles performance should get the W for them.
Prediction: France wins 4-1
Serbia hosting Spain
Serbia: Novak Djokovic, Viktor Troicki, Dusan Lajovic, Nenad Zimonjic
Spain: Pablo Carreno Busta, Albert-Ramos-Vinolas, Marcel Granollers, Marc Lopez
This will be more interesting than it looks on paper. Djoko should win both of his singles rubbers easily enough, but he's not the strongest doubles player in the world and a PCB-M Lopez team could get a W there. This tie will likely come down to how Troicki can do against Ramos-Vinolas or Granollers. Almost a coin flip tie, but I like the Spanish team's solidarity.
Prediction: Spain wins 3-2
