Lindley, who had played in 295 LPGA events without a win, shot a 5-under-par 67 and Jang a 68 in the final round, tying at 11-under 277.
"I am thrilled," Lindley said after winning on the first hole of the playoff. "I dreamed about this day for over 13 years. And, gosh, for awhile you kind of wonder if it's ever going to come."
Lindley said her approach shot on the playoff hole "was one of the best shots I hit today."
