By Amy TenneryFARMINGDALE, New York (Reuters) -The Americans walked away without the Ryder Cup crown on Sunday but their spine-tingling fightback on the final day at Bethpage Black was plenty to be proud about, said U.S. captain Keegan Bradley. “They were fighting the whole way, even when things were not looking good, and I didn’t expect anything different today,” he said. “Never more proud of anything in my life.”The American side ended the day with 8.5 points in singles, matching the highest total during the era of 12 singles matches. You think about the odds of something like that happening, just on a coin flip would be incredible,” said Bradley. The home crowd came to their aide on the final day, cheering and ruthlessly heckling the visitors in Farmingdale, New York.
