Isner cruises and Ferrer safely through

John Isner, a former top American college player, beat this year's top American college player in the first round of the US Open.

The 13th-seeded Isner defeated Marcos Giron 7-6(5) 6-2 7-6(2) on Tuesday. Giron earned his first spot in a Grand Slam tournament when he won the NCAA title for UCLA in May.

The big-serving Isner didn't face a break point. He has shown that a player can compete in college then succeed in the pros after a successful career at Georgia from 2004-07. He's the only American man currently ranked in the top 40 in the world.

Tenth-seeded Kei Nishikori of Japan cruised to a 6-2 6-4 6-2 victory over American Wayne Odesnik, showing no apparent effects from a toe injury that hampered his preparations.

"I'm very happy," Nishikori told ATP.com. "I was playing really well, an almost perfect game. [There are a] couple of things I have to work on still, but I'm happy to win today. It's not easy the first match after injury. I know how important this tournament is, and so hopefully I can go farther this week."

Pablo Andujar got a free pass to the second round after opponent Jack Sock retired hurt. Fabio Fognini eased past Andrey Golubev 6-4 6-4 6-2.
