NEW YORK (AP) - Roger Federer's U.S. Open got off to a late start but a routine one.
The 17-time major champion beat Grega Zemlja in straight sets Tuesday in a first-round match postponed from the night before because of rain. Federer is seeded seventh at Flushing Meadows, his worst since 2002. But he looked like the guy used to being seeded first in the 6-3, 6-2, 7-5 win.
Federer had 12 aces and 35 winners.
The 62nd-ranked Zemlja, from Slovenia, reached the third round at Wimbledon this year. That's one round further than Federer, who was stunned by 116th-ranked Sergiy Stakhovsky in his second match there.
Federer won 20 of 21 points at the net to advance in 93 minutes.
