THE COLONY, Texas — Jin Young Ko closed with seven straight pars for a 2-under 69 and a one-shot victory Sunday in the Volunteers of America Classic, her first start since losing the No. 1 world ranking.

Ko sank her shoulders when she made her par putt from just outside 3 feet on the final hole at Old American Golf Club, holding off Matilda Castren of Finland, who also shot 69.

The South Korean won for the first time this year.
