Russian Nikolay Davydenko warmed up for the US Open in the best possible manner as he beat Argentine 10th seed Agustin Calleri 6-4, 6-3 to win the New Haven event on Saturday.

The second seed broke once in the first set and twice in the second as he wrapped up victory in one hour, 21 minutes.

The win gave Davydenko his third title of the year, but his first on hard courts.

"It was good to play not so long matches, like one hour something, two sets," Davydenko said.

"Now I am happy. It is my third title already on hard courts - I have not won too many tournaments on hard."

Davydenko has never been beyond the third round at the US Open but said the victory was a big boost to his confidence going into the final Grand Slam tournament of the year.

"For my mind, to win the tournament here, I felt good already from the first round so I hope I play good [at the US Open].

Calleri rued a few missed chances to break in the first set.

"I had three or four break points, but he served very well," Calleri said.

"He didn't give me a chance to break him. He just played very well on the important points.

"Obviously I would have loved to win the tournament. On the other hand, I felt very good here."
