Somdev Devvarman had a bit of history added to his name as the Indian tennis player won the longest final on the ATP Challenger Tour to claim his fifth career title in Winnetka, United States.

Seventh seed Indian overcame stiff resistance from American Daniel Nguyen before prevailing 7-5 4-6 7-6(5) in the rain-hit final that lasted three hours and 31 minutes, turning out to be the longest summit clash in the ATP Challenger Tour history.

The match had been moved indoors at 3-3 in the deciding set after rain halted play for the fifth time. "The funny thing is, they all kept happening on my serve," Somdev said, referring to the rain delays.

"Even with those match points I thought I did well. He came up with some great shots and to be honest I'm just happy that I fought so hard. It wasn't the best tennis today, but I'm happy I fought and got through that one," he said.

Since winning Delhi Open in February, Somdev has played 13 tournaments and struggled go beyond many qualifiers or second rounds in main draws.
