PESARO, Italy (AP) Argentina picked Juan Martin del Potro to play doubles against Italy in the Davis Cup quarterfinals from Friday.
It will be Del Potro's first tie in four years, and his first Davis Cup doubles.
Wrist surgeries have limited his appearances, but he's finally sustained another comeback which included beating Stan Wawrinka en route to the third round of Wimbledon.
This is his first tie since the 2012 semifinals, and though he has a 12-4 record in the cup, all in singles, he was passed over by Argentina captain Daniel Orsanic, who preferred Federico Delbonis, who will open against Andreas Seppi, and Juan Monaco, playing his first tie in 2 1/2 years, in the singles.
Del Potro was paired on Thursday with Guido Pella, who made his debut in the first-round win over Poland.
Italy has returned to Pesaro's clay, the site of its first-round sweep of Switzerland. It hopes a six-match winning streak on home soil, going back to 2009, will help carry it to only a second semifinal in 18 years.
Fabio Fognini leads the team, and will oppose his old doubles partner Monaco in the second singles.
Against Del Potro and Pella, Italy has teamed Marco Cecchinato and Paolo Lorenzi, who have never played Davis Cup doubles.
The winner meets Britain or Serbia in the semifinals.
