Roger Federer finished with a flurry of aces and advanced to the fourth round of the Miami Open by beating Filip Krajinovic 7-5, 6-3 Monday.

In the final game, Federer smacked aces on the first three points. An ace on the next point was overturned by a replay review, and instead Krajinovic dumped the last shot into the net.

Federer finished with 14 aces and pulled away after converting only one of his first eight break-point chances.

Seeded fourth, Federer improved to 14-2 this year. He made his Miami debut 20 years ago and won the tournament in 2005, 2006 and 2017, when it was played on Key Biscayne.
