Lorena Ochoa tees off on the sixth hole during the third round of the LPGA Ginn Tribute. Ochoa fired a 70 on Saturday in Mount Pleasant, S.C.

Mount Pleasant, S.C. ? Leave it to Lorena Ochoa to find the sunny side of a tropical depression.

Ochoa shot a 2-under 70 to maintain her three-shot lead at the Ginn Tribute on Saturday, though three bogeys over the final six holes in drenching rains cost her a much larger advantage heading into the final round.

She finished at 11-under 205, three shots ahead of Nicole Castrale (68). Cristie Kerr (67) and rookie Angela Park (71) were four strokes behind the leader.

How long would it take the world’s No. 1 player to get over her errors? Apparently, not long at all.

“Tomorrow, you know, of course I’m going to be smiling and happy,” Ochoa said. “In a way, I don’t want to be sarcastic, but if you think about it, 2 under for a day like today is a really good round.”

Annika Sorenstam continued her injury comeback with a 2-over 74.

Sorenstam spent nearly two months recovering from a ruptured disk in her back. She hadn’t played a full 18 before this week and since the Kraft Nabisco Championships.

Ochoa was on her way to a great round at the RiverTowne Country Club.

She had shrugged off Park’s fast start of three straight birdies and the increasing rains of tropical depression Barry.

Ochoa holed out from the fairway for an eagle on the par-5 ninth. When she chipped in for birdie on the 12th hole, she was ahead by six.

But golf in the rain eventually took its toll.

After a lengthy delay on the 13th hole to squeegee off the green, Ochoa dropped a shot.

She then made back-to-back bogeys on the 16th and 17th holes, three-putting both greens. Ochoa had been 9 under on the par 5s here when she made bogey on the par-5 16th hole.

Even with the late mistakes, Ochoa remains in position to win her second LPGA Tour event in three weeks and third this season.

Ochoa wanted to focus on the positives of her round. “I feel angry and just a little frustrated playing so good and just finishing with those” bogeys, she said.

“The important thing is that I’m still in the lead, three shots, and I’m in good position for tomorrow,” Ochoa said. “So I’m happy to be there.”

Tournament officials moved up tee times and sent competitors off both the first and 10th holes in an attempt to beat the storm, which weakened to a tropical depression earlier Saturday.
