Casey out of US Open
Paul Casey has been forced to withdraw from the US Open through injury and will be replaced by 14-year-old Andy Zhang.
The former world number three has struggled all season after missing the first three months of the campaign with a dislocated shoulder sustained while snowboarding on Christmas Eve.
He returned to play in the WGC-Cadillac Championship and managed to finish in a share of 51st place.
But, he has either missed the cut or withdrawn in all but one of his subsequent seven events and will have it all to do to make the European Ryder Cup team for the renewal with the USA later this year.
The Englishman admitted his frustration at not being able to participate at San Francisco's Olympic Club and believes he has paid the price for returning to the sport when not fully fit.
"You're always disappointed to miss time due to injury, but it's especially true when you have to withdraw from the US Open," he told reporters.
"I've been trying to play my way back and I feel like I probably came back too soon originally."
Zhang will become the youngest player to play at the US Open since World War II after the China-born, Florida-based 14-year-old just missed out on qualifying for the major in a play-off.
