South Korean Grace Park, whose six career LPGA titles included a major win at the 2004 Kraft Nabisco Championship, said she was retiring Friday after her second round of the LPGA Championship. Park, 33, has struggled with back, hip and neck injuries. She underwent two operations and missed nearly three years on the LPGA Tour as a result. “I'm ready for a new phase in my life,” Park said. “It's my own fault for not taking care of my body.” Park, who has won more than $5 million in her career, captured her last title at the 2004 Nine Bridges Classic.
