Eunjung Yi (IHN'-juhng E) blew a six-stroke lead then hit a 10-foot birdie putt on the first playoff hole to defeat Morgan Pressel and capture her first LPGA victory Sunday in what might be the final Jamie Farr Owens Corning Classic. The 21-year-old Yi began the day with a four-shot lead. She birded two of the first three holes to go up six shots. Pressel, chasing her third career victory, pulled even by holing a wedge shot for eagle on the par-5 17th hole.
