Roger Federer appeared to lose focus in his first match back after the birth of his second set of twins, losing to 47th-ranked Jeremy Chardy of France 1-6, 6-3, 7-6 (6) in the second round of the Italian Open on Wednesday.
After cruising through the first set easily, Federer began to commit unforced errors at an alarming rate and Chardy quickly took advantage amid swirling wind at the Foro Italico.
Federer's boys, Leo and Lenny, were born last week, prompting the 17-time Grand Slam champion to withdraw from the Madrid Open. Federer and wife Mirka also have twin girls, Myla Rose and Charlene Riva, who turn 5 in July.
Rome is a key clay-court warmup for the French Open, which starts in 11 days.
