MEXICO CITY, Mexico - World number one Lorena Ochoa, who is fresh off capturing her second major title, highlights the 1.3 million dollar LPGA Corona Championship which begins Thursday in her native Mexico.

Ochoa, who won the Kraft Nabisco Championship on Sunday, will be after her 21st career title and her third-straight LPGA Tour victory.

Ochoa has won three of the four LPGA Tour events she has entered this season. She last won three straight events in August.

Ochoa possibly would have one more championship to her credit if not for Silvia Cavalleri's performance here last year.

Italy's Cavalleri entered last year's final round in a three-way tie with Ochoa and Julieta Granada atop the leaderboard, but claimed a two-shot victory with a seven-under-par to get to 20-under. It remains the only championship of Cavalleri's career.

Cavalleri, of Milan, has returned to defend her title, and Carin Koch - the event's inaugural champion in 2005 - is participating as well.

The tournament is being played at the par-72 Tres Marias Residential Golf Club just outside of Mexico City.
