Argentina 5 - 0 Germany
R4: Juan Monaco (ARG) d Tobias Kamke (GER) 64 76(2)
R5: Carlos Berlocq (ARG) d Christopher Kas (GER) 62 64
少了Del Potro能赢下这第一轮意义不小，队长也表达希望JMDP能参加八强的喊话。
“I hope Del Potro reconsiders his decision, but it going to be up to him.
The team has open doors for him. It would be important for us to increase our
future chances”, said Argentina captain Martin Jaite this weekend.
2010在里昂被法国宰了个0-5，这次在红土主场增加了一点机会。
USA 3 - 2 Brazil
R4: Thomaz Bellucci (BRA) d John Isner (USA) 26 64 67(7) 64 63
R5: Sam Querrey d Thiago Alves (BRA) 46 63 64 76(3)
Bellucci五盘击败Isner，没让美国轻松过关，硬是把战线延长到决胜点，可惜巴西的
第二单打实力仍旧有差距。
“I was fighting every point,” Bellucci said. “I was running every point.
For me is very special to beat him here.”
