THE COLONY, Texas (AP) — Her nearly two-year run at No. 1 in the women’s world golf ranking over, Jin Young Ko was back on top Thursday in the Volunteers of America Classic. Ko shot an 8-under 63 in hot conditions at Old American to take a one-stroke lead over fellow South Korean major champions and area residents In Gee Chun and Jeongeun Lee6. The 25-year-old Ko lost the No. 1 ranking when Nelly Korda won the KPMG Women’s PGA Championship on Sunday for her second straight victory. “That’s fine,” Ko said about dropping to No. 2. “And I’m still alive. So doesn’t matter really.”
