South Korea's Sei Young Kim has beaten Spaniard Carlota Ciganda in a playoff to win the LPGA Classic in Michigan.

Kim birdied the first extra hole to score her fifth career win after she and Ciganda finished the round locked on 17 under.

After bogeying the 18th in regulation to drop into the playoff, the 23-year-old Kim rebounded on the par-4 hole with a birdie.
