NEW YORK (AP) Roger Federer tied Andre Agassi for the second-most Grand Slam wins in the Open era by defeating Colombia's Santiago Giraldo 6-4, 6-3, 6-2 Monday in the first round of the U.S. Open.

The third-seeded Federer, a 16-time major champion, now has 224 Grand Slam wins, nine behind Jimmy Connors.

Federer showed a few signs of rust, losing his serve three times, but this one was never in doubt. He improved to 12-0 in first-round matches at Flushing Meadows and 57-6 overall.

Federer, who turned 30 on Aug. 8, is trying to win at least one major tournament for the ninth straight year and become the first 30-something man to win a Grand Slam title since Agassi won the 2003 Australian Open.
