Federer through after tough workout from `Bozo`
London: Six-times champion Roger Federer was forced to dig deep at Wimbledon again on Wednesday, the Swiss reaching the third round with a hard-fought 6-3, 6-7, 6-4, 7-6 victory over Serbian Ilija Bozoljac.
Federer, who came back from the brink to defeat Colombian Alejandro Falla in his opening match, had an uncomfortable time against the big-serving qualifier.
The number one seed, in unfamiliar territory on Court One, the first time he has been away from Centre Court at the All England Club since 2007, finally prevailed in two hours and 46 minutes.
Federer now takes on either Frenchman Arnaud Clement or Australian Peter Luczak.
