UPDATE 1-Golf-Dominant Ochoa clinches fourth LPGA title in a row

(Adds quotes, detail)

MIAMI, April 20 (Reuters) - World number one Lorena Ochoa became the first player in seven years to win four successive LPGA titles with a three-shot victory at the Ginn Open in Orlando on Sunday.

Mexican Ochoa, a stroke in front overnight at the Ginn Reunion Resort, signed off with a three-under-par 69 for a 19-under total of 269.

Although feeling fatigued over the closing stretch, she posted her fifth LPGA triumph of the season in just six starts and the 22nd of her remarkable career.

"For sure it was a great day today," the 26-year-old Guadalajara native told reporters. "It was different. It was a tough back nine and yes, I have another big trophy. I don't know. I'm going to ask my mommy where we should put it."

Rookie Yani Tseng of Taiwan closed with a 71 to finish second, five ahead of third-placed Suzann Pettersen of Norway, also after a 71.

Former world number one Annika Sorenstam of Sweden was the most recent player to win four consecutive titles on the LPGA Tour, doing so in 2001.

Only two other players have achieved the feat, Mickey Wright in 1962 and 1963 and fellow American Kathy Whitworth in 1969.
