South Korea's Inbee Park has won the first women's golf major of the year by four strokes after shooting a final round three under par 69 at the Mission Hills course in California.
It's Parks' second major title, having won the 2008 US Open.
New Zealand's Lydia Ko enjoyed her best round of the tournament on the final day, also scoring a three under par round to finish as the leading amateur and in a seven-way tie for 25th overall.
