Jenkins, Gimelstob Lead Americans at ATP New Haven

"This is big," said Jenkins, firing 19 aces en route to his first tour win. "I'm excited but I can't be too excited because I have another match to go tomorrow."

Jenkins started nervously but got a foothold in the match after breaking in the second set before overcoming more nerves in the end.

"I feel comfortable because I've been waiting for this," Jenkins said. "I wasn't relaxed in those final games, but I have to get used to this. I have to realize now that I'm on a stage."

Americans on the losing end Monday were Bobby Reynolds, straight-setted by Austria's Stefan Koubek, and Kevin Kim, edged by David Sanguinetti of Italy.

"I haven't won too many matches so far (this year)," said Koubek who was suspended three months for a drug infraction and had a knee injury earlier this year, "but I qualified last week in Cincinnati and now in New Haven. Being in the main draw is great for me."

Other un-seeds into the second round were Romanian Victor Hanescu (d. Horna in three tiebreaks), Russian Igor Andreev (d. Monaco), France's Cyril Saulnier (d. Wawrinka), Czech Tomas Zib (d. Muller in three), Italy's Andrea Seppi (d. Tursunov from a set down), and Spain's Fernando Verdasco (d. Hernych, bagel in the first).
