ADDS quotes, details World number one Ko Jin-young pulled away from second-ranked Kim Sei-young with five back-nine birdies Sunday to win the LPGA's season-ending Tour Championship by five strokes. Ko, who was playing just her fourth LPGA event of the pandemic-disrupted season, had only squeezed into the elite field with a tie for second on Monday at the US Women's Open. But the 25-year-old South Korean made the most of her opportunity, firing seven birdies in her six-under par 66 at Tiburon Golf Club in Naples, Florida. She rolled in a final birdie at the 72nd hole for an 18-under total of 270 and a convincing win over Kim and Australian Hannah Green, who shared second on 275.
