Firing Federer finds his mojo after rain break

Grand Slam king Roger Federer came back with renewed vigor 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 on Sunday.

The 42nd-ranked Granollers surprisingly led the second-seeded Swiss 5-2 when lightning and heavy rain suspended their afternoon match at Arthur Ashe Stadium.

After play resumed a couple of hours later, 17-time Grand Slam winner Federer conceded the first set and trailed 1-0 in the second before taking 18 of the next 20 games to secure victory.
