Inbee Park won the Lorena Ochoa Invitational on Sunday, holding off Carlota Ciganda for her fifth victory of the season and 17th LPGA Tour title.
The second-ranked South Korean star birdied the final two holes for a bogey-free eight-under 64 and a three-stroke victory over Ciganda in cloudy conditions at tree-lined Club de Golf Mexico.
"It was definitely the putter. It was really good this week," Park said. "I made a lot of birdies this week. It was a lot of fun today with Carlota playing so well. ... It was almost a perfect day today. I didn't make any mistakes, so I was able to focus on my game."
Ciganda shot 63. The Spaniard eagled the par-five second hole and had eight birdies and a bogey.
"I did the best I could," Ciganda said. "I putted really well today. I think that was the key. ... Inbee played unbelievable and she has lots of experience. She knows how to win."
