Los Angeles ? Se Ri Pak, widening her lead with an eagle on the hole she double bogeyed a day earlier, shot her second consecutive 4-under 68 Saturday to take a three-stroke advantage into the final round of the Office Depot Championship.

Annika Sorenstam, who came from 10 shots back on the last day to win last year, was second at 5-under 139 after a 68.

Laura Diaz, whose victory two weeks ago in Tucson, Ariz., was her first on the tour, was four shots behind Pak after shooting a second-round 69. Michelle Estill, whose lone LPGA win came in her rookie year of 1991, had a 70 that left her five shots behind Pak.

The 24-year-old Pak, the LPGA’s rookie of the year in 1998 and winner of 13 titles including three majors in her brief career, is playing her third event of the year and looking for her first 2002 win.

The first-day leader in the tournament at El Caballero Country Club, Pak seemed to be faltering during the second round when she hit her tee shot into a bunker and bogeyed the 160-yard, par-3 16th.

She quickly regained her composure.

On the 463-yard, par-5 No. 17, where she had hit in the water and three-putted from 11 feet for a 7 the previous day, she hit a good drive, stroked her 9-iron onto the fringe 18 feet from the pin, then rolled in the winding putt for an eagle 3.

Pak finished the round with five birdies after having seven the first day and the lone bogey.

Sorenstam tied Mickey Wright’s 37-year-old LPGA record for overcoming the biggest final-round deficit in a victory when she came from 10 shots back with a 66 last year. Sorenstam overtook struggling leader Pat Hurst, who shot 77, then beat Mi Hyun Kim on the first hole of a playoff.
