American wild card Ryan Sweeting completed his unlikely tournament run by capturing the US Clay Court Championship with a 6-4, 7-6 victory over Japan's Kei Nishikori on Sunday.
Sweeting, who managed to fend off a set point in the second set, became the first player to win the tournament as a wild card entry since fellow American Mardy Fish in 2006.
"I needed a little help to get in. I want to thank (the tournament) for the opportunity, and for giving me the wild card," Sweeting said during a courtside interview after playing in his first ATP final.
"It was a lot of fun. I'm looking forward to coming back and defending the title next year," he added.
Sweeting, who overcame six double faults for the match, did not face a break point in winning the first set but needed to climb out of a 5-4 deficit and a set point to force a tiebreaker in the second set.
The 23-year-old American, born in the Bahamas but a resident of Fort Lauderdale, Florida, will move up to 71st in the world, a career-best ranking.
