LOS ANGELES (AFP) - South Korean Lee Mi Rim fired seven birdies in a seven-under 65 on Sunday to post a record-equalling triumph in the LPGA Kia Classic in Carlsbad, California.

Her 20-under total of 278 matched the tournament record set by Cristie Kerr in 2015 - when the American powered past Lee for a two-shot victory.

Determined not to be disappointed again, overnight leader Lee opened her round with a birdie and birdied every other hole on the front nine as she pulled away from the field.

She finished six strokes in front of compatriot Ryu So Yeon, who carded a 66, and American Austin Ernst, who posted a 67.
