Westwood and Donald thrive
Lee Westwood and Luke Donald were all smiles after shooting a better-ball 59 - 13 under par - on the first day of Ryder Cup practice.
It enabled them to hand out what Westwood called "a proper drubbing" to Justin Rose and Ian Poulter in Chicago.
"I said there would be lots of birdies," said Donald, who as a Chicago resident for the past 15 years knows the Medinah course well and on a recent visit saw how little rough there was.
That was American captain Davis Love's idea, but Swede Peter Hanson was another to enjoy himself, grabbing six birdies and an eagle as he and Francesco Molinari beat debutant Nicolas Colsaerts and Martin Kaymer.
Rory McIlroy and Graeme McDowell look even more likely to stay together after beating Paul Lawrie and Sergio Garcia.
With predictions of noisy crowds for the match, Kaymer said: "To be honest, it was still fairly quiet out there today.
"I was expecting a little bit more, a little bit louder, but maybe they were only for the American teams there.
"Last time I played it was loud and a lot going on in Europe, so I didn't know anything different, so that's why I was a little surprised."
