Bradley made several key puts on the back nine to lead him and his partner Phil Mickelson to a 4 and 3 win over the European team of Luke Donald and Sergio Garcia.
But it was his enthusiasm and spirit that charged up the overflow galleries at Medinah Country Club as much as his fine play. And the magnitude of the moment was not lost on the young American.
“It was one of the most memorable days of my life", said Bradley
Jason Dufner and Zach Johnson overcame a slow start to give the Americans a second point, winning 3 and 2 over Ryder Cup veteran Lee Westwood and rookie Francesco Molinari.
The Europeans got their first point of the matches from the all-Irish team of Rory McIlroy and Graeme McDowell. The Euros almost blew a three-up lead through 12 holes before winning it 1 up against Americans Jim Furyk and Brandt Snedeker, when Snedeker hit an errant tee shot on the 18th tee.
In the morning's final match, both Tiger Woods and partner Steve Stricker were out of sorts and never looked comfortable in a 2 and 1 loss to Englishmen Justin Rose and Ian Poulter.
In the afternoon four-ball matches it's 2012 major champions Bubba Watson and Webb Simpson against Europe's Peter Hansen and Paul Lawrie; Mickelson and Bradley against McIlroy and McDowell; Dustin Johnson and Matt Kuchar against Justin Rose and Martin Kaymer of Germany; and Woods and Stricker versus Westwood and Belgium's Nicolas Colsaerts.Tags: Golf, Keegan Bradley, Medinah, Ryder Cup, Team Europe, Team USA
