Sophie Gustafson’s stunning collapse, and Karrie Webb’s short playoff miss opened the way for Seon Hwa Lee to come from nine shots back and win the Ginn Tribute on Sunday.

South Korea’s Lee two-putted from about 45 feet for par on the lone playoff hole, the 18th, then watched LPGA Hall of Famer Webb miss a 3-footer that would’ve extended things at RiverTowne Country Club.

Lee shot a 67 for her third LPGA title. She earned $390,000, one of the richest prizes in women’s golf.

It wouldn’t have happened without Gustafson’s improbable fall. Holding a six-shot lead when the day began, Gustafson had five bogeys and two double bogeys in her last 15 holes for a 7-over 79 that left her three shots from the playoff.
