MIAMI, Florida (Reuters) - Andy Roddick ground out a 5-7 6-2 6-4 win over qualifier Viktor Troicki of Serbia to reach the third round at the Sony Ericsson Open on Saturday.

The sixth-seeded American struggled to find his form but held on to wrap up the win having broken Troicki's spirit with a fantastic shot to secure the first point of the last game.

With Troicki serving at 5-4 down, Roddick hit a stunning crosscourt forehand winner that landed on the line leaving the American to pump his fist as the crowd rose to cheer.

"I was pretty lucky," Roddick said of the shot. "I didn't even see it when I hit it. I heard people yell and scream afterwards and I figured that was a good thing.

"As far as freak show trick shots go, that's up there. You don't hit shots like that every day," he added.

In the women's draw, world number two Ana Ivanovic breezed past Frenchwoman Emilie Loit 6-1 6-2 in her second round match.

The Serb, who hit 20 winners against six for Loit, served well and never faced a break point in the 45-minute match.
