Luke Donald's caddie-brother switches to Paul Casey

Christian Donald is at the Chevron World Challenge. His more famous brother, Luke Donald, is not.
Christian Donald, who has been his brother’s caddie for most of the decade, said they decided last month to part ways. Luke Donald has won four times, along with the World Cup with Paul Casey and Tiger Woods’ charity event.
“It’s been eight years,” Christian said. “That was a good run.”
He figured their relationship as brothers took precedence over the strain of working with each other inside the ropes. Christian Donald now caddies for Casey.
Lee Westwood has celebrated his stellar season by signing a new multi-year deal with Ping Golf. The biggest change for Westwood is that the Ping logo will return to the front of his cap.
Vijay Singh started and ended his 2009 season the same way – with knee surgery. The Fijian went winless this year for the first time since 1996.
