The 42-year-old Hartwiger, the 2002 winner from Birmingham, Ala., had five birdies and three bogeys. She was penalized a stroke after her ball moved on the 16th green.
I played very steady, said Hartwiger, trying to earn one of the 64 spots in match play. I only had one three-putt. On these greens, that is good.
Virginia Grimes, the 1998 winner from Meridian, Miss., opened with a 71, and Wendi Patterson-Golden of Sarasota, Fla., shot a 72. Two-time defending champion Meghan Bolger of Oakland Park, Fla., had a 75 on the 6,189-yard Donald Ross-designed course.
The tournament is open to amateurs 25 years old or older.
