Ko, 17, prepares for retirement

MELBOURNE--Only 17, top-ranked Lydia Ko says she’s planning to retire from golf by the time she’s 30, and become a psychologist. Ko makes her second start at No. 1 in the Women’s Australian Open at Royal Melbourne along with Karrie Webb and Australia’s Su Oh, an 18-year-old who won the Australian Ladies Masters last week in her second start as a professional. The South Korean-born Ko says she will soon start an on-line psychology degree to prepare for life after golf.
