Zhang to warm-up with Watson
The 14-year-old set to become the youngest player in US Open history this week hopes to practise with Masters champion Bubba Watson on Tuesday.
Beijing-born Andy Zhang, now based in Florida, was informed late on Monday that Paul Casey's withdrawal with a shoulder injury had opened up a place for him.
"Bubba is the Masters champ - I can't think of anyone better to play with," said Zhang, a year younger than Tadd Fujikawa was when he competed in 2006.
Zhang has lived in the States since he was 10, having taken up golf at six.
His mother is with him in San Francisco, but his father returned to China at the weekend thinking his son would probably remain a reserve for the second major of the season.
He was fifth on the original list, but moved up when three were called in after the publication of the world's top 60 on Monday - only Branden Grace and Spencer Levin earned exempt spots that way - and then became first alternate when Brandt Snedeker pulled out with a rib problem.
According to United States Golf Association records the youngest competitor prior to Fujikawa was Tyrell Garth, a month short of his 16th birthday when he played in 1941.
Zhang is not the youngest player in major history, however. He will be 14 years and six months on Thursday, while Young Tom Morris first played in the Open Championship at 14 years and four months in 1865.
Zhang did indeed get his game with Watson, while Tiger Woods practised with Casey Martin, the 40-year-old who qualified for the event 14 years after making history at Olympic as the first player ever to use a golf cart in a major.
Now a coach at the University of Oregon, Martin suffers from a birth defect in his right leg known as Klippel Trenaunay Weber Syndrome and he successfully sued the PGA Tour in 2001 for the right to use a cart during competition.
He finished 23rd in 1998 only a stroke behind Woods.
