Grand slam king Roger Federer has come back with renewed vigour after a weather delay to rout Spaniard Marcel Granollers 4-6 6-1 6-1 6-1 and charge into the fourth round of the US Open.
The 42nd-ranked Granollers surprisingly led the second-seeded Swiss 5-2 on Sunday (NZT Monday) when lightning and heavy rains suspended their afternoon match at Arthur Ashe Stadium.
After play resumed a couple of hours later, 17-times grand slam winner Federer conceded the first set and trailed 1-0 in the second before reeling off nine straight games and a total of 18 of the next 20 to register the one-sided victory.
''I was able to come back and turn it around, because Marcel started really on fire,'' 33-year-old Federer told the crowd.
''I'm happy the break helped me and I came out and played some great tennis.''
Five-times US Open winner Federer would next play either 17th seed Roberto Bautista Agut of Spain or France's Adrian Mannarino.
