The oldest and most prestigious championship in women's golf began the match- play portion of the competition Wednesday with the medalist disposing of Wigger, 3 & 2. Mackenzie took medalist honors after finishing 36 holes of stroke play at 3-under-par 139.
Tiffany Joh and In Kyung Kim, who each finished the stroke play portion two strokes behind Mackenzie, both played only 15 holes Wednesday. Joh defeated Alice Kim, 4 & 3 while Kim dispatched of Theresa Paik, 4 & 3.
The upset of the day came when Lauren Espinosa, a talented 19-year-old who qualified for the United States Women's Open, sneaked past 2004 U.S. Women's Amateur champion Jane Park, 1-up. Park also finished as the runner-up in 2003 and led this year's United States Women's Open held at Newport Country Club in Rhode Island after the first round.
Espinosa never trailed one of the tournament favorites, draining a putt for a birdie at the par-5 fourth to grab an early edge. The match was all square around the turn before the Hickory Creek, Texas native made a birdie at the 194-yard par-3 10th hole, then a par was good enough to increase the advantage at the par-5 11th.
Park evened the match with birdies at the 12th and 14th holes, but Espinosa made her second '2' of the back nine with a birdie at the par-3 15th before her bogey at the next hole again squared the match.
The match came down to the 18th hole, a sweeping dogleg left par-5, with Espinosa making a par to win the hole and pull off the surprise.
Things were much easier for Mackenzie, who struck first blood after Wigger made double bogey at the par-4 sixth hole. A par at the 10th hole built the advantage to 2-up, but Wigger's bogey at the par-4 13th was good enough to draw back within one.
Mackenzie increased the edge again with a birdie at the short par-3 15th and the match ended when Wigger could not convert a par at the par-4 16th hole.
