SYLVANIA, Ohio — Seventeen-year-old Lydia Ko broke free from a late tie with So Yeon Ryu, hitting a wedge to 4 feet for birdie on the 72nd hole on Sunday to win the Marathon Classic.

She became the youngest player to top $1 million in career earnings on the LPGA Tour.

Ryu had poured in a big-breaking, 25-foot birdie putt on the 17th to pull even.

But then Ko stuck her approach at the par-5 closing hole and calmly rolled in the birdie putt for a 6-under 65 that left her at 15-under 269. It was her second LPGA win as a pro to go with the two Canadian Open titles she grabbed as an amateur.

Ryu pushed a 6-footer at the 18th that would have forced a playoff.
