Robby Ginepri turned around a miserable season by winning the Indianapolis Championships on Sunday.
The American beat third-seeded compatirot Sam Querrey 6-2 6-4 in the final to complete a memorable week in Indiana.
Ginperi arrived at the tournament with just four wins from 17 matches on the ATP World Tour this season.
However, he won five in a row in Indianapolis to win his first title in four years - his previous one also coming at this tournament in 2005.
"This tournament is very special for me. Having won twice here is an amazing feeling," said the world number 95.
Third seed Querrey struggled to get into the contest and could not hide his disappointment at losing to his American compatriot.
"I didn't have rhythm on serve today, it was not there," he said.
"Still, I knew what to expect from his game. He got better as the week went on."
