MORELIA, Mexico: World No 1 and defending champion Lorena Ochoa seeks her third title in four years at this week's $1.3 million LPGA Corona Championship.

Ochoa seeks her second title of the season after a triumph at Thailand to open her 2009 campaign. She shared 12th earlier this month at the year's first women's golf major, the LPGA Kraft Nabisco.

"I'm very happy," Ochoa said. "It's always very nice to play in front of my crowd and my country. It's a lot of motivation. Playing here is always very special. My dream is to win the tournament, so I am going to try really hard."
