GENOA, Italy — Roger Federer rolled to a 6-3, 6-4, 6-1 win Friday over Simone Bolelli to give Switzerland a 2-0 lead against Italy in the Davis Cup playoffs.

Playing four days after his five-set loss to Juan Martin del Potro in the U.S. Open final, Federer shook off two break points in the opening game and was never in trouble against the 64th-ranked Bolelli.

Federer, who struggled with his serve in the U.S. Open final, had 10 aces to go with 35 winners.

Stanislas Wawrinka defeated Andreas Seppi 6-4, 6-1, 6-2 in the first match on the red clay courts at the Valletta Cambiaso club.

Federer and Wawrinka, the Olympic champions, will face Fabio Fognini and Potito Starace in doubles on Saturday, with reverse singles scheduled for Sunday.

Seppi and Bolelli wore black armbands to mourn six Italian soldiers killed in a bomb blast in Afghanistan on Thursday.

The winner of the best-of-five series will return to the World Group next year.
