Instead, the 102-year-old Chico woman became the oldest golfer ever to make a hole-in-one on a regulation course.
Because of the slope of the green, McLean and her partners couldn't see where her ball landed after she teed off.
'Where's my ball?' McLean asked.
Her friends, Elizabeth Rake and Kathy Crowder, found it in the cup.
'I said, 'Oh, my Lord. It can't be true. It can't be true.' I was so excited. And the girls were absolutely overcome,' McLean said.
It was McLean's first ace.
'Well everybody wants a hole-in-one, and I said, 'Why can't I have a hole-in-one?' I came within inches once,' McLean told television station KNVN.
McLean, who used a driver, broke the age record of 101 set by Harold Stilson in 2001 at Deerfield Country Club in Florida.
McLean, who has been featured in golf magazines before, will appear on 'The Tonight Show with Jay Leno' on April 24 to celebrate her accomplishment.
'For an old lady,' she said, 'I still hit the ball pretty good.'
