Park and Yoo go off at 7:42 a.m. local time Thursday on the 10th tee.
Park opened with a 2-under-par 70 a year ago, ending the first round tied for sixth. She grabbed control with a one-shot lead over Lizette Salas in the second round and never looked back on her way to a four-shot victory.
With Suzann Pettersen’s withdrawal with back pain this week, Park’s run at No. 1 in the Rolex Women’s World Rankings is assured to extend to 51 consecutive weeks. Rolex No. 3 Stacy Lewis can’t catch Park this week. She can, however, pass Suzann Pettersen and move up to No. 2 in the world with a first- or second-place finish.
In other pairings, Lewis, winner of the 2011 Kraft Nabisco, goes off with Anna Nordqvist, a two-time winner already this year, at 7:58 a.m. local time on the 10th tee.
Karrie Webb, another two-time winner this year who won the 2006 and 2000 Kraft Nabisco, goes off with Salas, who played in the final Sunday pairing with Park a year ago. They go off at 1:22 p.m. on the first tee.
