LOS ANGELES: World No 1 Lydia Ko clinched the second major of her career on Sunday with a dramatic victory at the ANA Inspiration after a late collapse from Thailand’s Ariya Jutanugarn. She held her nerve to conjure up a superb birdie on the 18th hole to complete back-to-back major wins. Ko’s three-under 69 left her at 12 under for the tournament, one clear of England’s Charley Hull and South Korea’s Chun In-Gee.
